技术领域Technical Field
本发明涉及通信领域，具体而言，涉及一种信息同步方法及系统、存储介质、电子装置。The present invention relates to the field of communications, and in particular to an information synchronization method and system, a storage medium, and an electronic device.
背景技术Background technique
在智慧家庭中，智能家电设备通过WIFI接入到家庭网络中，通常是通过配网操作将家庭内路由器的SSID(Service set Identifier，服务集标识，简称SSID)名称和密码发送给智能家电设备。当用户更换路由器SSID名称或者更换路由器的密码时，就需要重新对每一台智能家电设备重新进行配网操作，这将是一个费时费力的工作，特别是家庭内的智能家电设备比较多时。In a smart home, smart home appliances are connected to the home network through WIFI. Usually, the SSID (Service Set Identifier) name and password of the home router are sent to the smart home appliances through network configuration. When the user changes the SSID name of the router or changes the password of the router, it is necessary to re-configure the network for each smart home appliance, which will be a time-consuming and laborious task, especially when there are many smart home appliances in the home.
相关技术中，提供了一种基于路由器的WIFI信息自同步方案：主要步骤是当路由器的SSID名称或者密码发生变化，路由器和设备之间建立同步机制，使设备无需重新配网就可以自动从路由器获得新的WIFI信息，但是由于上述同步机制中路由器的参与是不可或缺的，不同厂家之间的路由器根设备不能很好的兼容，因此，难以实现互联互通。In the related art, a router-based WIFI information self-synchronization solution is provided: the main step is to establish a synchronization mechanism between the router and the device when the SSID name or password of the router changes, so that the device can automatically obtain new WIFI information from the router without re-configuring the network. However, since the participation of the router in the above synchronization mechanism is indispensable, the router root devices of different manufacturers are not well compatible, and therefore, it is difficult to achieve interoperability.
针对相关技术中，WIFI信息的同步依赖于路由器，无法实现设备之间的WIFI信息自同步等问题，尚未提出有效的技术方案。In view of the problems in the related art that the synchronization of WIFI information depends on the router and the self-synchronization of WIFI information between devices cannot be achieved, no effective technical solution has been proposed.

Therefore, the problem that the synchronization of WIFI information in the prior art depends on the router and the self-synchronization of WIFI information between devices cannot be realized, and it is ensured that the device changes the synchronization of the connection information through other connected devices after the connection information corresponding to the router is changed, thereby improving the flexibility of the device in the router connection and verifying the legitimacy of the unconnected device.
需要说明的是，上述握手帧是一种用于携带数据指示信息的数据帧，可以根据实际情况携带不同的数据信息。It should be noted that the above-mentioned handshake frame is a data frame used to carry data indication information, and can carry different data information according to actual conditions.
上述步骤S206的实现方式有多种，在一个可选实施例中，可以通过以下方案实现：确定第一握手帧携带的认证信息，其中，所述认证信息中包括：标识当前握手帧唯一性的第一随机数值、已连网设备对应的网络标识；在所述认证信息中的所述已连网设备对应的网络标识与所述未连网设备中存储的网络标识一致的情况下，根据预设网络密钥结合所述第一随机数值确定用于加密待同步的连接信息的第一密钥，其中，所述连接信息包括以下至少之一：路由器服务集标识的信息，路由器密码的信息；将所述认证信息和所述第一密钥进行数据打包，并添加消息的完整性校验标识以及第二随机数值，以确定向所述已连网设备发送包含预设网络密钥的第二握手帧。There are multiple ways to implement the above-mentioned step S206. In an optional embodiment, it can be implemented through the following scheme: determine the authentication information carried by the first handshake frame, wherein the authentication information includes: a first random value identifying the uniqueness of the current handshake frame, and a network identifier corresponding to the connected device; when the network identifier corresponding to the connected device in the authentication information is consistent with the network identifier stored in the non-connected device, determine the first key for encrypting the connection information to be synchronized according to the preset network key combined with the first random value, wherein the connection information includes at least one of the following: information on the router service set identifier, information on the router password; package the authentication information and the first key, and add a message integrity check identifier and a second random value to determine that a second handshake frame containing a preset network key is sent to the connected device.
也就是说，当未连接设备搜索到已连接设备后，已连接设备会在校验通过后，向未连接设备发送携带认证信息的用于指示后续连接认证同步的第一握手帧，进而通过第一握手帧对未连接设备的信道轮询操作进行停止，并固定信道，已确定后续的交互信道，进一步的，未连接设备基于接收到的第一握手帧，根据自身对应的预设网络密钥，以及确定出的用于指示待发送第二握手帧唯一性的第二随机数值，并增加用于验证数据包的发送者(即未连接设备)的消息的完整性校验标识，进而确定出用于握手交互的第二握手帧。That is to say, when an unconnected device searches for a connected device, the connected device will, after verification, send a first handshake frame carrying authentication information to the unconnected device to indicate subsequent connection authentication synchronization, and then stop the channel polling operation of the unconnected device through the first handshake frame, and fix the channel to determine the subsequent interaction channel. Furthermore, the unconnected device, based on the received first handshake frame, according to its own corresponding preset network key, and the second random value determined to indicate the uniqueness of the second handshake frame to be sent, adds a message integrity check identifier for verifying the sender of the data packet (i.e., the unconnected device), and then determines the second handshake frame used for handshake interaction.
在一个示例性实施例中，确定第一握手帧携带的认证信息之后，所述方法还包括：在所述认证信息中还包括有用于指示当前所述第一握手帧对应交互流程次数的序列号的情况下，确定已接收的多个第一握手帧对应的多个目标序列号与所述序列号是否存在匹配；在所述多个目标序列号与所述序列号不存在匹配的情况下，确定当前所述第一握手帧不为重复的第一握手帧；在所述多个目标序列号与所述序列号存在匹配的情况下，确定当前所述第一握手帧为重复的第一握手帧，所述第一握手帧对应的握手流程结束。In an exemplary embodiment, after determining the authentication information carried by the first handshake frame, the method also includes: when the authentication information also includes a sequence number indicating the number of interaction processes corresponding to the current first handshake frame, determining whether multiple target sequence numbers corresponding to multiple received first handshake frames match the sequence number; when there is no match between the multiple target sequence numbers and the sequence number, determining that the current first handshake frame is not a repeated first handshake frame; when there is a match between the multiple target sequence numbers and the sequence number, determining that the current first handshake frame is a repeated first handshake frame, and the handshake process corresponding to the first handshake frame ends.
简而言之，未连网设备与已连网设备的进行交互中的第一握手帧通过序列号进行本次交互流程的标识，当序列号相同证明对应的交互流程被重复执行，不相同则证明当前第一握手帧对应的交互流程未出现重复交互过程。In short, the first handshake frame in the interaction between an unconnected device and a connected device uses a serial number to identify the interaction process. If the serial numbers are the same, it proves that the corresponding interaction process is repeated. If they are different, it proves that there is no repeated interaction process in the interaction process corresponding to the current first handshake frame.
可选地，在目标区域存在已连网设备的情况下，向所述目标区域广播包含未连网设备中存储的网络标识的数据信息之后，所述方法还包括：确定未连网设备待轮询的信道列表，其中，所述信道列表用于指示所述未连网设备通信的信道以及所述信道的数量；根据所述信道列表确定向所述目标区域进行广播的时间周期；在所述时间周期内获取到信道验证成功的指示信息的情况下，停止向所述目标区域进行广播，其中，所述信道验证成功用于指示信道接收到已联网设备发送的交互信息，所述交互信息包括第一握手帧。Optionally, when there are connected devices in the target area, after broadcasting data information containing network identifiers stored in non-connected devices to the target area, the method further includes: determining a channel list to be polled by non-connected devices, wherein the channel list is used to indicate the channels for communication of the non-connected devices and the number of channels; determining a time period for broadcasting to the target area based on the channel list; and stopping broadcasting to the target area when indication information of successful channel verification is obtained within the time period, wherein the successful channel verification is used to indicate that the channel has received interactive information sent by connected devices, and the interactive information includes a first handshake frame.
例如，目标对象更改了SSID名称或者密码后，信道可能与原来的不同，并且由于路由器以及家电设备通常使用2.4G频段进行无线交互，因此未连网设备需要在13个信道上进行轮询，以发现已入网设备。初始从信道1开始，后续从轮询停止的下一个信道开始。每个信道上停留3秒钟，发送5帧，间隔512毫秒。当未连接设备第一次收到校验通过的握手帧，停止信道轮询，固定在握手step1帧中携带的信道，并对信道中传输过来的数据进行解析，进而确定出握手帧对应的内容。For example, after the target object changes the SSID name or password, the channel may be different from the original one, and because routers and home appliances usually use the 2.4G frequency band for wireless interaction, unconnected devices need to poll on 13 channels to discover connected devices. Initially start from channel 1, and then start from the next channel where polling stops. Stay on each channel for 3 seconds, send 5 frames, and the interval is 512 milliseconds. When the unconnected device receives the handshake frame that passes the verification for the first time, it stops channel polling, fixes the channel carried in the handshake step1 frame, and parses the data transmitted in the channel to determine the content corresponding to the handshake frame.
在一个示例性实施例中，在目标区域存在已连网设备的情况下，向所述目标区域广播包含未连网设备中存储的网络标识的数据信息之前，所述方法还包括：确定预设的过滤名单，其中，所述过滤名单用于指示已连网设备当前使用的连接信息无法被同步使用；在存在于所述过滤名单的已入网设备发送所述第一握手帧的情况下，禁止执行生成第二握手帧的操作。In an exemplary embodiment, when there are networked devices in the target area, before broadcasting data information containing network identifiers stored in non-networked devices to the target area, the method also includes: determining a preset filter list, wherein the filter list is used to indicate that connection information currently used by networked devices cannot be used synchronously; and prohibiting the operation of generating a second handshake frame when a networked device present in the filter list sends the first handshake frame.
例如，如果已入网设备在过滤名单，则忽略该已入网设备。与所有已入网设备的通信均失败后继续信道轮询。对于多个已入网设备，可以根据收到握手帧的先后顺序进行选择，并且已加入过滤名单的已入网设备的连接信息将无法同步到未连接设备上，在接收到已加入过滤名单的已入网设备发送的用于交互的第一握手帧之后，禁止未连接设备在验证成功的情况下生成对应的第二握手帧，并结束未连接设备与已加入过滤名单的已入网设备的交互流程。For example, if a connected device is in the filter list, the connected device is ignored. After all communications with all connected devices fail, channel polling continues. For multiple connected devices, selection can be made based on the order in which the handshake frames are received, and the connection information of the connected devices that have been added to the filter list will not be synchronized to the unconnected devices. After receiving the first handshake frame for interaction sent by the connected device that has been added to the filter list, the unconnected device is prohibited from generating the corresponding second handshake frame if the verification is successful, and the interaction process between the unconnected device and the connected device that has been added to the filter list is terminated.
在一个示例性实施例中，接收所述已连网设备根据所述数据信息反馈的用于单播交互的第一握手帧之后，所述方法还包括：在所述已连网设备存在多个且每一个所述已连网设备都反馈第一握手帧的情况下，根据每一个所述已连网设备反馈第一握手帧的时间点确定时序列表；根据所述时序列表的先后顺序进行所述第一握手帧是否符合预设条件的选择验证。In an exemplary embodiment, after receiving the first handshake frame for unicast interaction fed back by the connected device based on the data information, the method further includes: when there are multiple connected devices and each of the connected devices feeds back the first handshake frame, determining a timing sequence list based on the time point at which each of the connected devices feeds back the first handshake frame; and performing selection verification on whether the first handshake frame meets preset conditions based on the sequence of the timing sequence list.
例如，未连网设备可能会收到多个已入网设备的第一握手帧。根据系统资源的情况，可以维护一到多个已入网设备的通信，但与每个已入网设备通信最多尝试3次，因此，需要根据第一握手帧对应的反馈时间点，确定选择认证的次序。For example, a non-networked device may receive the first handshake frames of multiple networked devices. Depending on the system resources, communication with one or more networked devices can be maintained, but communication with each networked device can be attempted at most three times. Therefore, the order of selecting authentication needs to be determined based on the feedback time point corresponding to the first handshake frame.
在本实施例中提供了另一种信息同步方法，图3是根据本发明实施例的信息同步方法的流程图(二)，该流程包括如下步骤：In this embodiment, another information synchronization method is provided. FIG. 3 is a flow chart (II) of the information synchronization method according to an embodiment of the present invention. The flow chart includes the following steps:
步骤S302，获取未连网设备发送的包含未连网设备中存储的网络标识的数据信息，其中，所述未连网设备用于指示目标对象更换连接信息后中断连网的设备；Step S302, obtaining data information sent by a non-networked device and including a network identifier stored in the non-networked device, wherein the non-networked device is used to indicate a device that is disconnected from the network after the target object changes its connection information;
步骤S304，在确定所述数据信息中包含的未连网设备中存储的网络标识与自身网络标识相同的情况下，向所述未连网设备发送用于单播交互的第一握手帧；Step S304: When it is determined that the network identifier stored in the non-networked device contained in the data information is the same as its own network identifier, a first handshake frame for unicast interaction is sent to the non-networked device;
步骤S306，接收所述未连网设备在确定所述第一握手帧符合预设条件之后发送的用于指示同步的第二握手帧；Step S306, receiving a second handshake frame for indicating synchronization, which is sent by the non-networked device after determining that the first handshake frame meets a preset condition;
步骤S308，根据所述第二握手帧对当前连接信息进行加密，以得到用于同步的目标连接信息。Step S308: encrypt the current connection information according to the second handshake frame to obtain target connection information for synchronization.
通过上述步骤，获取未连网设备发送的包含未连网设备中存储的网络标识的数据信息，其中，未连网设备用于指示目标对象更换连接信息后中断连网的设备；在确定数据信息中包含的未连网设备中存储的网络标识与自身网络标识相同的情况下，向未连网设备发送用于单播交互的第一握手帧；接收未连网设备在确定第一握手帧符合预设条件之后发送的用于指示同步的第二握手帧；根据第二握手帧对当前连接信息进行加密，以得到用于同步的目标连接信息，也就是说，通过已连网设备与未连网设备之间的握手帧交互，进行更换连接信息的自主同步，继而实现设备之间的连接信息的同步交互，因此，可以解决现有技术中WIFI信息的同步依赖于路由器，无法实现设备之间的WIFI信息自同步，确保了设备在路由器对应的连接信息变更后通过其他已连接设备的进行更换连接信息的同步，提升了设备在路由器连接的灵活性，并验证了未连接设备的合法性。Through the above steps, the data information sent by the unconnected device and containing the network identifier stored in the unconnected device is obtained, wherein the unconnected device is used to indicate the device that is disconnected from the network after the target object changes the connection information; when it is determined that the network identifier stored in the unconnected device contained in the data information is the same as its own network identifier, a first handshake frame for unicast interaction is sent to the unconnected device; a second handshake frame for indicating synchronization sent by the unconnected device after determining that the first handshake frame meets the preset conditions is received; the current connection information is encrypted according to the second handshake frame to obtain the target connection information for synchronization, that is, through the handshake frame interaction between the connected device and the unconnected device, the autonomous synchronization of the connection information is changed, and then the synchronous interaction of the connection information between the devices is realized. Therefore, the problem that the synchronization of WIFI information in the prior art depends on the router and the self-synchronization of WIFI information between devices cannot be realized, and it is ensured that the device changes the connection information through other connected devices after the connection information corresponding to the router is changed. The flexibility of the device in the router connection is improved, and the legitimacy of the unconnected device is verified.
在一个示例性实施例中，在确定所述数据信息中包含的未连网设备中存储的网络标识与自身网络标识相同的情况下，向所述未连网设备发送用于单播交互的第一握手帧，包括：在所述未连网设备中存储的网络标识与自身网络标识相同的情况下，确定所述未连网设备存在与目标区域，且所述未连网设备被允许执行单播交互；根据所述单播交互对应的预设条件确定待携带的认证信息，以确定对应的第一握手帧，其中，所述认证信息中包括：标识当前握手帧唯一性的第一随机数值、已连网设备与路由器连接的工作信道、已连网设备对应的网络标识、当前所述第一握手帧对应交互流程次数的序列号。In an exemplary embodiment, when it is determined that the network identifier stored in the unconnected device contained in the data information is the same as its own network identifier, a first handshake frame for unicast interaction is sent to the unconnected device, including: when the network identifier stored in the unconnected device is the same as its own network identifier, determining that the unconnected device exists in the target area and that the unconnected device is allowed to perform unicast interaction; determining the authentication information to be carried according to the preset conditions corresponding to the unicast interaction to determine the corresponding first handshake frame, wherein the authentication information includes: a first random value identifying the uniqueness of the current handshake frame, the working channel connecting the connected device to the router, the network identifier corresponding to the connected device, and the serial number of the number of interaction processes corresponding to the current first handshake frame.
为了更好的理解上述信息同步方法的过程，以下结合两个可选实施例对上述信息同步方法流程进行说明。In order to better understand the process of the above information synchronization method, the above information synchronization method process is described below in combination with two optional embodiments.
本发明可选实施例中，主要提供了一种WIFI信息自同步的方法，当用户更换路由器SSID名称或者更换路由器的密码时，只需要重新对一台智能家电设备进行配网操作，其他智能家电设备通过智能家电设备间的同步机制可以进行WIFI信息自同步。In an optional embodiment of the present invention, a method for self-synchronization of WIFI information is mainly provided. When a user changes the SSID name of a router or changes the password of a router, it is only necessary to re-configure the network for one smart home appliance. Other smart home appliances can self-synchronize WIFI information through the synchronization mechanism between smart home appliances.
为了更好的理解本发明实施例以及可选实施例的技术方案，以下对本发明实施例以及可选实施例中可能出现的名词术语进行说明，但不用于限定以下场景的应用。In order to better understand the technical solutions of the embodiments and optional embodiments of the present invention, the terms and concepts that may appear in the embodiments and optional embodiments of the present invention are explained below, but are not used to limit the application of the following scenarios.
已连网设备：用户更换路由器SSID名称或者更换路由器的密码后，重新连入家庭网络的智能家电设备。重新连网的方式包括但不限于设备配网、本发明可选实施例描述的方式等。Connected devices: smart home appliances that are reconnected to the home network after the user changes the router SSID name or the router password. The reconnection method includes but is not limited to device network configuration and the method described in the optional embodiment of the present invention.
未连网设备：用户更换路由器SSID名称或者更换路由器的密码后，原来可以接入家庭网络，现在不能正常连网的智能家电设备。Devices not connected to the network: After the user changes the router SSID name or the router password, the smart home appliances that were previously able to access the home network but now cannot connect to the network normally.
网络地址Network ID：家庭网络的标识。通常在设备配网绑定阶段设置到设备中，同一个家庭网络，Network ID相同。Network ID: The ID of the home network. Usually it is set in the device during the device configuration and binding phase. For the same home network, the Network ID is the same.
网络密钥Network Key：在一个家庭网络内，经过用户配网绑定的智能家电设备可以共享一个Network Key。Network Key: In a home network, smart home appliances that have been bound by user configuration can share a Network Key.
作为一种可选的实施方式，已连网设备与未连网设备的进行多次握手确定，继而实现WIFI信息自同步，如图4所示为本发明可选实施例的信息同步方法的交互示意图，包含以下步骤：As an optional implementation, the connected device and the unconnected device perform multiple handshakes to determine, and then implement WIFI information self-synchronization. FIG4 is an interactive schematic diagram of an information synchronization method of an optional embodiment of the present invention, which includes the following steps:
步骤1、搜索已连网设备帧。Step 1: Search for the connected device frame.
发送：未连网设备发送，广播形式。Send: sent by a device not connected to the Internet, in broadcast form.
内容：Network ID。Content: Network ID.
接收：已连网设备接收，如果Network ID与自身的相同，则发送握手step1帧(数据帧)。Receiving: The connected device receives. If the Network ID is the same as its own, it sends the handshake step 1 frame (data frame).
步骤2：握手step1帧；Step 2: handshake step1 frame;
发送：已连网设备，单播形式，直接发送未连网设备。Send: Connected devices, unicast mode, directly send to unconnected devices.
内容：Network ID、一个递增的序列号，每个握手step1帧均不同、一个随机数Nonce-A，每个握手step1帧均不同、工作信道，与路由器连接的工作信道。Contents: Network ID, an increasing sequence number, which is different for each handshake step1 frame, a random number Nonce-A, which is different for each handshake step1 frame, and the working channel connected to the router.
接收：未连网设备接收，如果Network ID与自身的相同，则发送握手step2帧。Receiving: The unconnected device receives. If the Network ID is the same as its own, it sends the handshake step 2 frame.
步骤3：3)握手step2帧；Step 3: 3) handshake step2 frame;
发送：未连网设备，单播形式，直接发送已连网设备。Send: For devices not connected to the network, use unicast mode to send directly to devices connected to the network.
内容：Network ID、序列号，握手step1帧中的序列号、一个随机数Nonce-B，每个握手step2帧均不同、MIC，SHA256(Network Key网络密钥,Nonce-A)；Contents: Network ID, sequence number, the sequence number in the handshake step 1 frame, a random number Nonce-B, which is different for each handshake step 2 frame, MIC, SHA256 (Network Key, Nonce-A);
也就是说，未连接设备在向已连接设备发送握手step2帧时，为了保证消息的完整性通过接收的握手step1帧中的随机数A和自身存储的网络密钥通过预设的散列算法进行运算确定出对应的MIC对应的哈希值，进而已连接设备可以对收到的MIC进行解析，以确定握手step2帧是由接收到握手step1帧的未连接设备发送的，保证了流程的一致性和安全性。That is to say, when an unconnected device sends a handshake step2 frame to a connected device, in order to ensure the integrity of the message, the random number A in the received handshake step1 frame and the network key stored in itself are calculated through a preset hash algorithm to determine the hash value corresponding to the MIC. Then the connected device can parse the received MIC to determine that the handshake step2 frame is sent by the unconnected device that received the handshake step1 frame, ensuring the consistency and security of the process.
接收：已连网设备接收，如果Network ID与自身的相同，校验序列号和MIC，则发送握手step3帧。Receiving: The connected device receives. If the Network ID is the same as its own, the sequence number and MIC are verified, and then the handshake step 3 frame is sent.
步骤4：握手step3帧Step 4: Handshake step3 frame
发送：已连网设备，单播形式，直接发送未连网设备。Send: Connected devices, unicast mode, directly send to unconnected devices.
内容：Network ID；序列号，握手step1帧中的序列号；加密的SSID和密码，密钥使用SHA256(Network Key,Nonce-A,Nonce-B)；MIC(Messages Integrity Check，消息完整性检查，简称MIC)，SHA256(Network Key,Nonce-B)；Contents: Network ID; Serial number, the serial number in the handshake step 1 frame; Encrypted SSID and password, the key uses SHA256 (Network Key, Nonce-A, Nonce-B); MIC (Messages Integrity Check, MIC for short), SHA256 (Network Key, Nonce-B);
简单来说，握手step3帧是在接收到握手step2帧的基础上发送的，并且为保证整个交互流程的一致性，根据握手step2帧中的随机数B和自身存储的网络密钥通过预设的散列算法进行运算确定出对应的MIC对应的哈希值(即SHA256(Network Key,Nonce-B))，进而未连接设备可以对收到的MIC进行解析，以确定握手step3帧是由接收到握手step2帧的已连接设备发送的，并且为了使得路由器的SSID和密码的安全性更高，通过握手step3帧之前所有交互的握手帧中携带的随机数值结合自身存储的网络密钥生成用于加密连接信息的下发密钥(即SHA256(Network Key,Nonce-A,Nonce-B))。Simply put, the handshake step3 frame is sent based on the received handshake step2 frame, and to ensure the consistency of the entire interaction process, the hash value corresponding to the corresponding MIC (i.e., SHA256 (Network Key, Nonce-B)) is determined by calculating the random number B in the handshake step2 frame and the network key stored in itself through a preset hash algorithm. Then, the unconnected device can parse the received MIC to determine that the handshake step3 frame is sent by the connected device that received the handshake step2 frame. In order to make the router's SSID and password more secure, the random value carried in all interactive handshake frames before the handshake step3 frame is combined with the network key stored in itself to generate a downlink key (i.e., SHA256 (Network Key, Nonce-A, Nonce-B)) for encrypting the connection information.
接收：未连网设备接收，如果Network ID与自身的相同，校验序列号和MIC，则解密SSID和密码，完成WIFI信息同步。Receiving: The device not connected to the network receives. If the Network ID is the same as its own, the serial number and MIC are verified, then the SSID and password are decrypted to complete the WIFI information synchronization.
本发明可选实施例中，还提供了一种未连网设备的操作方式，包含以下内容：In an optional embodiment of the present invention, an operation method of a non-networked device is also provided, including the following contents:
步骤S502：确定开始时机，当每次使用原有SSID和密码连接路由器失败后。未联网设备开启与已连网设备的自同步交互功能。Step S502: Determine the start time, when each attempt to connect to the router using the original SSID and password fails, the non-networked device starts the self-synchronization interaction function with the networked device.
步骤S504：当用户更改了SSID名称或者密码后，信道可能与原来的不同，因此未连网设备需要在13个信道上进行轮询，以发现已入网设备。初始从信道1开始，后续从轮询停止的下一个信道开始。每个信道上停留3秒钟，发送5帧，间隔512毫秒。Step S504: When the user changes the SSID name or password, the channel may be different from the original one, so the unconnected device needs to poll on 13 channels to find the connected devices. Initially start from channel 1, and then start from the next channel where the polling stops. Stay on each channel for 3 seconds, send 5 frames, and the interval is 512 milliseconds.
步骤S506：通过交互流程发现已连网设备并发出同步WIFI信息的操作信息。Step S506: discover the connected device through the interactive process and send out operation information for synchronizing WIFI information.
可选地，当未联网设备第一次收到校验通过的握手step1帧，停止信道轮询，固定在握手step1帧中携带的信道。并且需要说明的是每次通信时间最长5秒，从收到握手step1帧开始。未连网设备可能会收到多个已入网设备的握手step1帧。根据系统资源的情况，可以维护一到多个已入网设备的通信，但与每个已入网设备通信最多尝试3次。Optionally, when the non-networked device receives the handshake step1 frame that has passed the verification for the first time, it stops channel polling and fixes the channel carried in the handshake step1 frame. It should be noted that each communication time is up to 5 seconds, starting from the receipt of the handshake step1 frame. The non-networked device may receive handshake step1 frames from multiple networked devices. Depending on the system resources, the communication with one or more networked devices can be maintained, but the communication with each networked device is attempted at most 3 times.
可选地，如果已入网设备在过滤名单，则忽略该已入网设备。与所有已入网设备的通信均失败后继续信道轮询。对于多个已入网设备，可以根据收到握手step1帧的先后顺序进行选择。Optionally, if an already connected device is in the filter list, the already connected device is ignored. After all communication with all the already connected devices fails, channel polling continues. For multiple already connected devices, selection can be made based on the order in which the handshake step 1 frames are received.
步骤S508：获取到WIFI信息后，如果WIFI信息与保存的不一致，则记录发送WIFI信息的已入网设备的MAC(Media Access Control Address，媒体存取控制位址，简称MAC)，关闭所有与已入网设备的通信，并退出WIFI信息同步操作，开始尝试连接路由器。Step S508: After obtaining the WIFI information, if the WIFI information is inconsistent with the saved one, the MAC (Media Access Control Address, MAC for short) of the connected device that sent the WIFI information is recorded, all communications with the connected device are closed, and the WIFI information synchronization operation is exited, and an attempt to connect to the router is started.
步骤S600：如果连接路由器成功，则保存WIFI信息；否则，丢弃WIFI信息，将对应的已入网设备置于过滤名单中(超时10分钟)，使用原来的SSID和密码连接路由器，重新触发WIFI信息同步操作。Step S600: If the connection to the router is successful, the WIFI information is saved; otherwise, the WIFI information is discarded, the corresponding networked device is placed in the filter list (timeout 10 minutes), the original SSID and password are used to connect to the router, and the WIFI information synchronization operation is re-triggered.
作为一种可选的实施方式，已连网设备的操作方式包含以下内容：As an optional implementation, the operation mode of the connected device includes the following:
1)在与路由器连接的信道上监听搜索已连网设备帧，不影响与路由器的连接，不影响正常的通信。1) Listen and search for connected device frames on the channel connected to the router without affecting the connection with the router or normal communication.
2)通过交互流程完成WIFI信息同步。2) Complete WIFI information synchronization through interactive process.
3)可同时维护与一到多个未入网设备的通信。3) Can maintain communication with one or more non-networked devices at the same time.
4)每次通信时间最长5秒，从第一次发送握手step1帧开始。4) Each communication lasts up to 5 seconds, starting from the first sending of the handshake step 1 frame.
需要说明的是，本发明可选实施例描述的WIFI信息同步不依赖于路由器，只需要重新对一台智能家电设备进行配网操作，其他智能家电设备自动完成WIFI信息同步。WIFI信息同步机制通过Network Key机制实现已连网设备对未连网设备的验证，不需要云端的参与；同时通过Network Key实现了WIFI信息的加密传输。WIFI信息同步机制从未连网设备搜索已连网设备开始，经过两次交互实现了WIFI信息同步。交互流程中既没有影响已入网设备的正常通信，又实现了未入网设备的WIFI信息快速同步；同时未入网设备还设置了过滤机制，防止已入网设备传递了错误的WIFI信息。WIFI信息同步机制实现一对一、一对多、多对一和多对多的WIFI信息自同步。可以快速完成整个家庭网络内的WIFI信息同步。It should be noted that the WIFI information synchronization described in the optional embodiment of the present invention does not rely on the router. It only needs to re-configure the network for one smart home appliance, and other smart home appliances will automatically complete the WIFI information synchronization. The WIFI information synchronization mechanism uses the Network Key mechanism to realize the verification of the unconnected device by the connected device, without the participation of the cloud; at the same time, the encrypted transmission of WIFI information is realized through the Network Key. The WIFI information synchronization mechanism starts with the unconnected device searching for the connected device, and realizes the WIFI information synchronization after two interactions. The interaction process does not affect the normal communication of the connected device, and realizes the rapid synchronization of the WIFI information of the unconnected device; at the same time, the unconnected device is also equipped with a filtering mechanism to prevent the connected device from transmitting the wrong WIFI information. The WIFI information synchronization mechanism realizes one-to-one, one-to-many, many-to-one and many-to-many WIFI information self-synchronization. The WIFI information synchronization in the entire home network can be completed quickly.
进一步避免了，基于路由器的WIFI信息同步方案主要依赖于路由器与设备之间的同步机制的限制性，进而使得智能家电设备间可同时进行一对一、一对多、多对一和多对多的WIFI信息自同步。WIFI信息同步不依赖于路由器，也不依赖于云端，未连网设备可自动发现已连网设备，未连网设备可自动过滤已连网设备，已连网设备可自动验证未连网设备，WIFI信息同步不影响已连网设备的正常通信。This further avoids the limitation of the synchronization mechanism between routers and devices that is mainly relied on in the router-based WIFI information synchronization solution, thereby enabling one-to-one, one-to-many, many-to-one and many-to-many WIFI information self-synchronization between smart home appliances. WIFI information synchronization does not rely on routers or the cloud. Unconnected devices can automatically discover connected devices, unconnected devices can automatically filter connected devices, and connected devices can automatically verify unconnected devices. WIFI information synchronization does not affect the normal communication of connected devices.
综上，通过本发明可选实施例，利用已连网设备可自动发现未连网设备，已连网设备需要验证未连网设备，使得不能通过验证的未连网设备不能进行WIFI信息自同步，并且该WIFI信息自同步流程不需要云端参与，而且WIFI信息自同步不影响已连网设备的正常通信，在WIFI信息(SSID和密码)同步需要加密，可进行一对一、一对多、多对一和多对多的WIFI信息自同步，不产生过多的网络流量。In summary, through the optional embodiments of the present invention, the connected device can automatically discover the unconnected device, the connected device needs to verify the unconnected device, so that the unconnected device that cannot pass the verification cannot perform WIFI information self-synchronization, and the WIFI information self-synchronization process does not require cloud participation, and the WIFI information self-synchronization does not affect the normal communication of the connected device. When the WIFI information (SSID and password) synchronization needs to be encrypted, one-to-one, one-to-many, many-to-one and many-to-many WIFI information self-synchronization can be performed without generating excessive network traffic.
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.
在本实施例中还提供了一种信息同步系统，该系统用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。图5是根据本发明实施例的信息同步系统的结构框图，如图5所示，该系统包括：In this embodiment, an information synchronization system is also provided, which is used to implement the above embodiments and preferred implementation modes, and the descriptions that have been made are omitted. FIG5 is a structural block diagram of an information synchronization system according to an embodiment of the present invention, as shown in FIG5 , the system includes:
已连接设备52、未连接设备54；Connected device 52, unconnected device 54;
其中，已连网设备52，用于获取未连网设备发送的包含未连网设备中存储的网络标识的数据信息，其中，所述未连网设备用于指示目标对象更换连接信息后中断连网的设备；在确定所述数据信息中包含的未连网设备中存储的网络标识与自身网络标识相同的情况下，向所述未连网设备发送用于单播交互的第一握手帧；接收所述未连网设备发送的用于指示同步的第二握手帧，根据所述第二握手帧对当前连接信息进行加密，以得到用于同步的目标连接信息；The networked device 52 is used to obtain data information sent by a non-networked device containing a network identifier stored in the non-networked device, wherein the non-networked device is used to indicate a device that is disconnected from the network after the target object changes the connection information; when it is determined that the network identifier stored in the non-networked device contained in the data information is the same as its own network identifier, send a first handshake frame for unicast interaction to the non-networked device; receive a second handshake frame sent by the non-networked device for indicating synchronization, and encrypt the current connection information according to the second handshake frame to obtain the target connection information for synchronization;
未连网设备54，用于在目标区域存在已连网设备的情况下，向所述目标区域广播包含未连网设备中存储的网络标识的数据信息，其中，所述已连网设备用于指示目标对象更换连接信息后重新连网的设备；接收所述已连网设备发送的第一握手帧，在所述第一握手帧符合预设条件的情况下，向所述已连网设备发送包含预设网络密钥的第二握手帧。The non-networked device 54 is used to broadcast data information containing a network identifier stored in the non-networked device to the target area when there is a networked device in the target area, wherein the networked device is used to indicate the device that reconnects to the network after the target object changes the connection information; receive a first handshake frame sent by the networked device, and send a second handshake frame containing a preset network key to the networked device when the first handshake frame meets a preset condition.
通过上述系统，在目标区域存在已连网设备的情况下，向目标区域广播包含未连网设备中存储的网络标识的数据信息，其中，已连网设备用于指示目标对象更换连接信息后重新连网的设备；接收已连网设备根据数据信息反馈的用于单播交互的第一握手帧；在第一握手帧符合预设条件的情况下，向已连网设备发送包含预设网络密钥的第二握手帧，以获取已连网设备根据第二握手帧确定的目标连接信息，其中，目标连接信息用于指示已加密的已连网设备的当前连接信息，也就是说，通过已连网设备与未连网设备之间的握手帧交互，进行更换连接信息的自主同步，继而实现设备之间的连接信息的同步交互，因此，可以解决现有技术中WIFI信息的同步依赖于路由器，无法实现设备之间的WIFI信息自同步，确保了设备在路由器对应的连接信息变更后通过其他已连接设备的进行更换连接信息的同步，提升了设备在路由器连接的灵活性，并验证了未连接设备的合法性。Through the above system, when there are connected devices in the target area, data information containing network identifiers stored in unconnected devices is broadcast to the target area, wherein the connected devices are used to indicate devices that reconnect to the network after the target object changes connection information; a first handshake frame for unicast interaction fed back by the connected device according to the data information is received; when the first handshake frame meets the preset conditions, a second handshake frame containing a preset network key is sent to the connected device to obtain the target connection information determined by the connected device according to the second handshake frame, wherein the target connection information is used to indicate the encrypted current connection information of the connected device, that is, through the handshake frame interaction between the connected device and the unconnected device, autonomous synchronization of changing the connection information is performed, and then synchronous interaction of the connection information between the devices is realized. Therefore, the problem that the synchronization of WIFI information in the prior art depends on the router and the self-synchronization of WIFI information between devices cannot be realized, and it is ensured that the device changes the synchronization of the connection information through other connected devices after the connection information corresponding to the router is changed, thereby improving the flexibility of the device in the router connection and verifying the legitimacy of the unconnected device.
需要说明的是，上述握手帧是一种用于携带数据指示信息的数据帧，可以根据实际情况携带不同的数据信息。在与路由器连接的信道上监听搜索已连网设备，不影响与路由器的连接，不影响正常的通信。It should be noted that the handshake frame is a data frame for carrying data indication information, and can carry different data information according to actual conditions. Listening and searching for connected devices on the channel connected to the router does not affect the connection with the router and does not affect normal communication.
在一个示例性实施例中，上述系统还包括：路由器，用于为已连网设备和未连网设备提供网络。In an exemplary embodiment, the system further includes: a router, configured to provide a network for networked devices and non-networked devices.
在一个示例性实施例中，上述未连网设备，还用于确定第一握手帧携带的认证信息，其中，所述认证信息中包括：表示握手帧次数的序列号、标识当前握手帧唯一性的第一随机数值、已连网设备与路由器连接的工作信道、已连网设备对应的网络标识；在所述认证信息中的所述已连网设备对应的网络标识与所述未连网设备中存储的网络标识一致的情况下，根据预设网络密钥结合所述第一随机数值确定用于加密待同步的连接信息的第一密钥，其中，所述连接信息包括以下至少之一：路由器服务集标识的信息，路由器密码的信息；将所述认证信息和所述第一密钥进行数据打包，并添加消息的完整性校验标识以及第二随机数值，以确定向所述已连网设备发送包含预设网络密钥的第二握手帧。In an exemplary embodiment, the above-mentioned non-networked device is also used to determine the authentication information carried by the first handshake frame, wherein the authentication information includes: a serial number indicating the number of handshake frames, a first random value identifying the uniqueness of the current handshake frame, a working channel connecting the networked device and the router, and a network identifier corresponding to the networked device; when the network identifier corresponding to the networked device in the authentication information is consistent with the network identifier stored in the non-networked device, a first key for encrypting the connection information to be synchronized is determined based on a preset network key combined with the first random value, wherein the connection information includes at least one of the following: information on the router service set identifier, information on the router password; the authentication information and the first key are data packaged, and a message integrity check identifier and a second random value are added to determine that a second handshake frame containing a preset network key is sent to the networked device.
也就是说，当未连接设备搜索到已连接设备后，已连接设备会在校验通过后，向未连接设备发送携带认证信息的用于指示后续连接认证同步的第一握手帧，进而通过第一握手帧对未连接设备的信道轮询操作进行停止，并固定信道，已确定后续的交互信道，进一步的，未连接设备基于接收到的第一握手帧，根据自身对应的预设网络密钥，以及确定出的用于指示待发送第二握手帧唯一性的第二随机数值，并增加用于验证数据包的发送者(即未连接设备)的消息的完整性校验标识，进而确定出用于握手交互的第二握手帧。That is to say, when an unconnected device searches for a connected device, the connected device will, after verification, send a first handshake frame carrying authentication information to the unconnected device to indicate subsequent connection authentication synchronization, and then stop the channel polling operation of the unconnected device through the first handshake frame, and fix the channel to determine the subsequent interaction channel. Furthermore, the unconnected device, based on the received first handshake frame, according to its own corresponding preset network key, and the second random value determined to indicate the uniqueness of the second handshake frame to be sent, adds a message integrity check identifier for verifying the sender of the data packet (i.e., the unconnected device), and then determines the second handshake frame used for handshake interaction.
在一个示例性实施例中，上述未连网设备，还用于在所述认证信息中还包括有用于指示当前所述第一握手帧对应交互流程次数的序列号的情况下，确定已接收的多个第一握手帧对应的多个目标序列号与所述序列号是否存在匹配；在所述多个目标序列号与所述序列号不存在匹配的情况下，确定当前所述第一握手帧不为重复的第一握手帧；在所述多个目标序列号与所述序列号存在匹配的情况下，确定当前所述第一握手帧为重复的第一握手帧，所述第一握手帧对应的握手流程结束。In an exemplary embodiment, the above-mentioned non-networked device is also used to determine whether there is a match between multiple target sequence numbers corresponding to multiple received first handshake frames and the sequence number when the authentication information also includes a sequence number indicating the number of interaction processes corresponding to the current first handshake frame; when there is no match between the multiple target sequence numbers and the sequence number, determine that the current first handshake frame is not a repeated first handshake frame; when there is a match between the multiple target sequence numbers and the sequence number, determine that the current first handshake frame is a repeated first handshake frame, and the handshake process corresponding to the first handshake frame ends.
简而言之，未连网设备与已连网设备的进行交互中的第一握手帧通过序列号进行本次交互流程的标识，当序列号相同证明对应的交互流程被重复执行，不相同则证明当前第一握手帧对应的交互流程未出现重复交互过程。In short, the first handshake frame in the interaction between an unconnected device and a connected device uses a serial number to identify the interaction process. If the serial numbers are the same, it proves that the corresponding interaction process is repeated. If they are different, it proves that there is no repeated interaction process in the interaction process corresponding to the current first handshake frame.
在一个示例性实施例中，上述未连网设备，还用于确定未连网设备待轮询的信道列表，其中，所述信道列表用于指示所述未连网设备通信的信道以及所述信道的数量；根据所述信道列表确定向所述目标区域进行广播的时间周期；在所述时间周期内获取到信道验证成功的指示信息的情况下，停止向所述目标区域进行广播，其中，所述信道验证成功用于指示信道接收到已联网设备发送的交互信息，所述交互信息包括第一握手帧。In an exemplary embodiment, the above-mentioned non-networked device is also used to determine a channel list to be polled by the non-networked device, wherein the channel list is used to indicate the channels for communication of the non-networked device and the number of channels; determine the time period for broadcasting to the target area according to the channel list; and stop broadcasting to the target area if indication information of successful channel verification is obtained within the time period, wherein the successful channel verification is used to indicate that the channel has received interaction information sent by a networked device, and the interaction information includes a first handshake frame.
例如，目标对象更改了SSID名称或者密码后，信道可能与原来的不同，并且由于路由器以及家电设备通常使用2.4G频段进行无线交互，因此未连网设备需要在13个信道上进行轮询，以发现已入网设备。初始从信道1开始，后续从轮询停止的下一个信道开始。每个信道上停留3秒钟，发送5帧，间隔512毫秒。当未连接设备第一次收到校验通过的握手帧，停止信道轮询，固定在握手step1帧中携带的信道，并对信道中传输过来的数据进行解析，进而确定出握手帧对应的内容。For example, after the target object changes the SSID name or password, the channel may be different from the original one, and because routers and home appliances usually use the 2.4G frequency band for wireless interaction, unconnected devices need to poll on 13 channels to discover connected devices. Initially start from channel 1, and then start from the next channel where polling stops. Stay on each channel for 3 seconds, send 5 frames, and the interval is 512 milliseconds. When the unconnected device receives the handshake frame that passes the verification for the first time, it stops channel polling, fixes the channel carried in the handshake step1 frame, and parses the data transmitted in the channel to determine the content corresponding to the handshake frame.
在一个示例性实施例中，上述未连网设备，还用于确定预设的过滤名单，其中，所述过滤名单用于指示已连网设备当前使用的连接信息无法被同步使用；在存在于所述过滤名单的已入网设备发送所述第一握手帧的情况下，禁止执行生成第二握手帧的操作。In an exemplary embodiment, the above-mentioned non-networked device is also used to determine a preset filter list, wherein the filter list is used to indicate that the connection information currently used by the networked device cannot be used synchronously; when the networked device present in the filter list sends the first handshake frame, the operation of generating the second handshake frame is prohibited.
例如，如果已入网设备在过滤名单，则忽略该已入网设备。与所有已入网设备的通信均失败后继续信道轮询。对于多个已入网设备，可以根据收到握手帧的先后顺序进行选择，并且已加入过滤名单的已入网设备的连接信息将无法同步到未连接设备上，在接收到已加入过滤名单的已入网设备发送的用于交互的第一握手帧之后，禁止未连接设备在验证成功的情况下生成对应的第二握手帧，并结束未连接设备与已加入过滤名单的已入网设备的交互流程。For example, if a connected device is in the filter list, the connected device is ignored. After all communications with all connected devices fail, channel polling continues. For multiple connected devices, selection can be made based on the order in which the handshake frames are received, and the connection information of the connected devices that have been added to the filter list will not be synchronized to the unconnected devices. After receiving the first handshake frame for interaction sent by the connected device that has been added to the filter list, the unconnected device is prohibited from generating the corresponding second handshake frame if the verification is successful, and the interaction process between the unconnected device and the connected device that has been added to the filter list is terminated.
在一个示例性实施例中，上述未连网设备，还用于在所述已连网设备存在多个且每一个所述已连网设备都反馈第一握手帧的情况下，根据每一个所述已连网设备反馈第一握手帧的时间点确定时序列表；根据所述时序列表的先后顺序进行所述第一握手帧是否符合预设条件的选择验证。In an exemplary embodiment, the above-mentioned non-networked device is also used to determine a timing sequence list according to the time point when each of the networked devices feeds back the first handshake frame when there are multiple networked devices and each of the networked devices feeds back the first handshake frame; and select and verify whether the first handshake frame meets preset conditions according to the sequence of the timing sequence list.
例如，未连网设备可能会收到多个已入网设备的第一握手帧。根据系统资源的情况，可以维护一到多个已入网设备的通信，但与每个已入网设备通信最多尝试3次，因此，需要根据第一握手帧对应的反馈时间点，确定选择认证的次序。For example, a non-networked device may receive the first handshake frames of multiple networked devices. Depending on the system resources, communication with one or more networked devices can be maintained, but communication with each networked device can be attempted at most three times. Therefore, the order of selecting authentication needs to be determined based on the feedback time point corresponding to the first handshake frame.
在一个示例性实施例中，上述已连网设备，还用于在所述未连网设备中存储的网络标识与自身网络标识相同的情况下，确定所述未连网设备存在与目标区域，且所述未连网设备被允许执行单播交互；根据所述单播交互对应的预设条件确定待携带的认证信息，以确定对应的第一握手帧，其中，所述认证信息中包括：标识当前握手帧唯一性的第一随机数值、已连网设备与路由器连接的工作信道、当前所述第一握手帧对应交互流程次数的序列号。In an exemplary embodiment, the above-mentioned networked device is also used to determine that the non-networked device exists in the target area and that the non-networked device is allowed to perform unicast interaction when the network identifier stored in the non-networked device is the same as its own network identifier; determine the authentication information to be carried according to the preset conditions corresponding to the unicast interaction to determine the corresponding first handshake frame, wherein the authentication information includes: a first random value identifying the uniqueness of the current handshake frame, the working channel connecting the networked device to the router, and the serial number of the number of interaction processes corresponding to the current first handshake frame.
