智能家居系统的加解密控制方法、装置、家居设备Intelligent home system encryption and decryption control method, device, home equipment技术领域Technical field

本发明涉及网络技术通信领域，尤其涉及一种智能家居系统的加解密控制方法、装置、家居设备。The present invention relates to the field of network technology communication, and in particular, to a method and device for encrypting and decrypting a smart home system, and a home device.

背景技术Background technique

全球范围内信息技术创新不断加快，信息领域新产品、新服务、新业态大量涌现，不断激发新的消费需求，在这种情况下，智能家居应运而生。在当前的智能家居产品的控制系统中，为了避免发送的消息被他人盗取，往往会对传送的控制指令进行加密，现在的智能家居产品中往往采用以下加密方式：发送端对控制指令进行加密，接收端对控制指令进行解密，且所有的智能家居都是采用相同的加密、解密方式。由此又会产生另一个弊端，如果他人破解了智能家居系统的加密方式，就能够控制所有的智能家居设备执行相应操作，也即智能家居中的所有设备都存在被攻击的可能性，因此，若采用此种方式，智能家居的安全性则得不到较好的保证，会给用户的人身以及财务安全造成非常大的损失；此外，智能家居系统的加密方式被破解后，为了解决安全故障还需花费大量的人力物力重新开发新的加密方式并进行评估，由此可见，现有的加密方法存在非常大的弊端。Global information technology innovation has been accelerating, new products, new services, and new formats have emerged in the information field, constantly inspiring new consumer demand. In this case, smart homes have emerged. In the current control system of smart home products, in order to prevent the sent messages from being stolen by others, the transmitted control commands are often encrypted. In the current smart home products, the following encryption methods are often used: the sender encrypts the control commands. The receiving end decrypts the control command, and all smart homes use the same encryption and decryption methods. Therefore, another drawback occurs. If someone else cracks the encryption method of the smart home system, it can control all the smart home devices to perform corresponding operations, that is, all devices in the smart home have the possibility of being attacked, therefore, If this method is adopted, the security of the smart home will not be well guaranteed, which will cause great loss to the user's personal and financial security. In addition, the encryption method of the smart home system is cracked, in order to solve the security failure. It takes a lot of manpower and resources to re-develop new encryption methods and evaluate them. It can be seen that the existing encryption methods have very big drawbacks.

具体实施方式detailed description

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例只是本发明中一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

实施例一：Embodiment 1:

为了提高智能家居系统的安全性，给用户的人身和财物安全提供更好的保证，本发明实施例提供一种智能家居系统的加密控制方式，如图1所示，包括：In order to improve the security of the smart home system, the user and the security of the user are provided with a better guarantee. The embodiment of the invention provides an encryption control method for the smart home system, as shown in FIG. 1 , which includes:

S101：从设备与加密算法对应关系表中，获取当前待控制智能家居设备对应的加密算法，所述设备与加密算法对应关系表中包含各智能家居设备对应的加密算法，且至少两个智能家居设备所对应的加密算法不同。S101: Acquire an encryption algorithm corresponding to the current smart home device to be controlled in the correspondence table between the device and the encryption algorithm, where the correspondence table between the device and the encryption algorithm includes an encryption algorithm corresponding to each smart home device, and at least two smart homes The encryption algorithm corresponding to the device is different.

本实施例中的设备与加密算法对应关系表中包含各智能家居设备对应的加密算法，且至少两个智能家居设备所对应的加密算法不同，应当理解的是，设备与加密算法对应关系表中包含的各智能家居设备对应的加密算法可以全部都不相同，如表一所示：The correspondence between the device and the encryption algorithm in this embodiment includes an encryption algorithm corresponding to each smart home device, and the encryption algorithms corresponding to at least two smart home devices are different. It should be understood that the device and the encryption algorithm correspond to the relationship table. The encryption algorithms corresponding to each smart home device may be different, as shown in Table 1:

表一Table I

智能家居Smart home空调air conditioning电视TV洗衣机washing machine冰箱refrigerator..............加密算法Encryption Algorithm加密算法AEncryption algorithm A加密算法BEncryption algorithm B加密算法CEncryption algorithm C加密算法DEncryption algorithm D……......

设备与加密算法对应关系表中包含的各智能家居设备对应的加密算法可以部分相同，如表二所示：The encryption algorithm corresponding to each smart home device included in the correspondence table between the device and the encryption algorithm may be partially the same, as shown in Table 2:

表二Table II

智能家居Smart home空调air conditioning电视TV洗衣机washing machine冰箱refrigerator..............

加密算法Encryption Algorithm加密算法AEncryption algorithm A加密算法AEncryption algorithm A加密算法CEncryption algorithm C加密算法DEncryption algorithm D……......

S102：根据获取的加密算法，对待发送的控制指令进行加密后，发送给待控制智能家居设备。S102: Encrypt the control command to be sent according to the obtained encryption algorithm, and send the control command to the smart home device to be controlled.

应当理解的是，本实施例中发送加密后的控制指令给待控制的智能家居设备，可以是在控制终端执行，也可以是在云服务器侧执行。It should be understood that, in this embodiment, the encrypted control command is sent to the smart home device to be controlled, which may be performed on the control terminal or on the cloud server side.

当在云服务器侧执行时，用户可以直接登录云服务器，例如用户可以通过配置相应的端口、主机名等进入云服务器，通过云服务器向待控制的智能家居设备发送控制指令，其相应的加密方式为：用户进入云服务器后，云服务器从设备与加密算法对应关系表中，获取当前待控制智能家居设备对应的加密算法，然后云服务器根据获取的加密算法，对待发送的控制指令进行加密后，发送给待控制智能家居设备。When running on the cloud server side, the user can directly log in to the cloud server. For example, the user can enter the cloud server by configuring the corresponding port and host name, and send a control command to the smart home device to be controlled through the cloud server. After the user enters the cloud server, the cloud server obtains the encryption algorithm corresponding to the current smart home device to be controlled, and then the cloud server encrypts the control command to be sent according to the obtained encryption algorithm. Send to the smart home device to be controlled.

当在控制终端侧执行时，控制终端从从设备与加密算法对应关系表中，获取当前待控制智能家居设备对应的加密算法，然后控制终端根据获取的加密算法，对待发送的控制指令进行加密后，通过云服务器发送给待控制智能家居设备。应当理解的是，本实施例中的控制终端可以是手机、笔记本、平板电脑、车载电脑等，也可以是智能家居系统中的控制端，例如智能家居系统的控制面板。When executing on the control terminal side, the control terminal acquires an encryption algorithm corresponding to the current smart home device to be controlled from the slave device and the encryption algorithm correspondence table, and then the control terminal encrypts the control command to be sent according to the obtained encryption algorithm. , sent to the smart home device to be controlled through the cloud server. It should be understood that the control terminal in this embodiment may be a mobile phone, a notebook, a tablet computer, a vehicle-mounted computer, etc., or may be a control terminal in a smart home system, such as a control panel of a smart home system.

此外，需要说明的是，本实施例中的表可以由智能家居系统开发商在控制端内预置，也支持用户自定义设置，且可同步到云服务器侧。In addition, it should be noted that the table in this embodiment may be preset by the smart home system developer in the control terminal, and also supports user-defined settings, and may be synchronized to the cloud server side.

应当理解的是，本实施例中的加密算法包括但不限于现在已有的各种加密算法，还可以采用本实施例提供的加密映射表。本实施例提供的加密映射表中包括待加密字符和加密符的对应关系，这种对应关系可以是预先设定的一种随机对应关系，也可以是预先设定的一种遵循某种规律的对应关系。控制终端从设备与加密算法的对应关系表中获取当前待控制智能家居设备对应的加密算法，如果获取到的加密算法为加密映射表，就会通过将控制指令中的待加密字符根据待加密字符与加密符的映射关系全部映射成加密符的方式对控制指令进行加密。It should be understood that the encryption algorithm in this embodiment includes, but is not limited to, various encryption algorithms that are currently available, and the encryption mapping table provided in this embodiment may also be used. The cryptographic mapping table provided in this embodiment includes a correspondence between a character to be encrypted and a cipher, and the corresponding relationship may be a preset random correspondence, or may be a preset one that follows a certain rule. Correspondence relationship. The control terminal obtains an encryption algorithm corresponding to the current smart home device to be controlled from the correspondence table between the device and the encryption algorithm. If the obtained encryption algorithm is an encryption mapping table, the character to be encrypted in the control instruction is determined according to the character to be encrypted. The control instruction is encrypted in such a manner that the mapping relationship with the cipher is all mapped to a cipher.

为了更好的理解本发明，下面用加密映射表对控制指令进行加密作进一步说明。例如，预先设定的加密映射表的一部分如表三所示：For a better understanding of the present invention, the control instructions are encrypted using a crypto map to further illustrate the following. For example, a part of the preset encryption mapping table is shown in Table 3:

表三Table 3

若传送的控制指令为“35hjyCDIGJ”，获取到的加密方式是采用加密映射表，则根据待加密字符与加密符的对应关系，加密后传送的控制指令是“vb43Rvf.fgdsfgRFASASSsd”。If the control command transmitted is "35hjyCDIGJ", and the obtained encryption method is an encryption mapping table, the control command transmitted after encryption is "vb43Rvf.fgdsfgRFASASSsd" according to the correspondence between the character to be encrypted and the encryption character.

智能家居系统中，采用多种加密算法可以有效提高智能家居系统的安全性，但为了更好的保证用户的生命财产安全，提高智能家居系统被他人破解的难度，还可以对智能家居系统各设备对应采用的加密算法进行动态更新。在本实施例中可以通过下述办法对加密算法进行动态更新：In the smart home system, multiple encryption algorithms can effectively improve the security of the smart home system, but in order to better ensure the safety of the user's life and property, and to improve the difficulty of the smart home system being cracked by others, it is also possible to use the smart home system equipment. Corresponding to the encryption algorithm used for dynamic update. In this embodiment, the encryption algorithm can be dynamically updated by the following methods:

接收加密算法更新请求，根据该加密算法更新请求对设备与加密算法对应关系表进行更新，并启用更新后的设备与加密算法对应关系表；加密算法更新请求包含更新后的设备与加密算法对应关系表，且更新后的设备与加密算法对应关系表与原设备与加密算法对应关系表中的至少一组智能家居设备与加密算法的对应关系不同。Receiving an encryption algorithm update request, and updating the request to the device and the encryption algorithm according to the encryption algorithmCorresponding relationship table is updated, and the updated correspondence table between the device and the encryption algorithm is enabled; the encryption algorithm update request includes the updated correspondence table between the device and the encryption algorithm, and the updated correspondence table between the device and the encryption algorithm and the original device and The correspondence between at least one set of smart home devices and the encryption algorithm in the correspondence table of the encryption algorithm is different.

应当理解的是，当在云服务器侧向待控制的智能家居设备发送控制指令时，加密算法更新指令可以由云服务器自动生成，也可以是用户通过云服务器发送。It should be understood that when the cloud server side sends a control instruction to the smart home device to be controlled, the encryption algorithm update instruction may be automatically generated by the cloud server, or may be sent by the user through the cloud server.

当由控制终端向待控制的智能家居设备发送控制指令时，包含两种如下方式：When the control terminal sends a control command to the smart home device to be controlled, there are two ways as follows:

方式一：控制终端向云服务器发送加密算法更新请求，加密算法请求包含更新后的设备与加密算法对应关系表，更新后的设备与加密算法对应关系表与原设备与加密算法对应关系表中的至少一组智能家居设备与加密算法的对应关系不同，且控制终端本地启用更新后的设备与加密算法对应关系表；Manner 1: The control terminal sends an encryption algorithm update request to the cloud server, and the encryption algorithm request includes the updated correspondence table between the device and the encryption algorithm, and the updated correspondence table between the device and the encryption algorithm and the correspondence between the original device and the encryption algorithm. The correspondence between the at least one smart home device and the encryption algorithm is different, and the control terminal locally enables the updated correspondence table between the device and the encryption algorithm;

方式二：控制终端接收云服务器下发的加密算法更新指令，更新指令中包含更新后的设备与加密算法对应关系表，更新后的设备与加密算法对应关系表与控制终端本地的原设备与加密算法对应关系表中的至少一组智能家居设备与加密算法的对应关系不同，将控制终端本地的原设备与加密算法对应关系表更新为所述更新后的设备与加密算法对应关系表。Manner 2: The control terminal receives the encryption algorithm update instruction sent by the cloud server, and the update instruction includes the updated correspondence table between the device and the encryption algorithm, the updated correspondence table between the device and the encryption algorithm, and the original device and the encryption local to the control terminal. The correspondence between the at least one set of the smart home device and the encryption algorithm in the algorithm correspondence table is different, and the original device and the encryption algorithm correspondence table locally controlled by the control terminal are updated to the updated device and the encryption algorithm correspondence table.

应当理解的是，动态更新时，可以对系统中的某一个或部分多个家居设备的加密算法进行更新，也可以对系统中所有的家居设备的加密算法进行更新，这种更新可以是当前的各家居设备所采用的各不同加密算法之间的互相交换，也可以是新的加密算法对原有的加密算法的替换。It should be understood that, when dynamically updating, the encryption algorithm of one or a part of the plurality of home devices in the system may be updated, and the encryption algorithm of all the home devices in the system may be updated, and the update may be current. The exchange of different encryption algorithms used by each home device may also be a replacement of the original encryption algorithm by a new encryption algorithm.

例如智能家居系统原设备与加密算法对应关系如上表三所示，若更新后的设备与加密算法对应关系表与原设备与加密算法对应关系表中的各组智能家居设备与加密算法的对应关系都不相同，则更新后的设备与加密算法对应关系可以如下表四所示：For example, the correspondence between the original device of the smart home system and the encryption algorithm is as shown in Table 3 above. If the correspondence between the updated device and the encryption algorithm correspondence table and the original device and the encryption algorithm correspondence table are in the relationship between the smart home devices and the encryption algorithm, If they are different, the relationship between the updated device and the encryption algorithm can be as shown in Table 4 below:

表四Table 4

智能家居Smart home空调air conditioning电视TV洗衣机washing machine冰箱refrigerator..............加密算法Encryption Algorithm加密算法EEncryption algorithm E加密算法FEncryption algorithm F加密算法GEncryption algorithm G加密算法HEncryption algorithm H……......

若更新后的设备与加密算法对应关系表与原设备与加密算法对应关系表中的部分智能家居设备与加密算法的对应关系相同，则更新后的设备与加密算法对应关系可以如下表五所示：If the correspondence between the updated device and the encryption algorithm correspondence table is the same as the correspondence between the smart device and the encryption algorithm in the correspondence between the original device and the encryption algorithm, the correspondence between the updated device and the encryption algorithm may be as shown in Table 5 below. :

表五Table 5

智能家居Smart home空调air conditioning电视TV洗衣机washing machine冰箱refrigerator..............加密算法Encryption Algorithm加密算法AEncryption algorithm A加密算法AEncryption algorithm A加密算法GEncryption algorithm G加密算法BEncryption algorithm B……......

应当理解的是，本实施例请求或者更新指令中可以仅包含需要更新的设备与加密算法对应关系，也可以包含全部各设备与加密算法之间的对应关系。例如，当仅需要对空调或者电视的对应的加密算法更新时，请求或者更新指令中可以仅包含空调与加密算法的对应关系，或者电视与加密算法的对应关系。It should be understood that the request or update instruction in this embodiment may only include the correspondence between the device to be updated and the encryption algorithm, and may also include the correspondence between all devices and the encryption algorithm. For example, when only the corresponding encryption algorithm of the air conditioner or the television is required to be updated, the request or the update instruction may include only the correspondence between the air conditioner and the encryption algorithm, or the correspondence between the television and the encryption algorithm.

本实施例中，在由控制终端向待控制的智能家居设备发送控制指令的情况下，对智能家居系统的加密算法进行动态更新，若采用方式一进行动态更新，控制终端向云服务器发送加密算法更新请求时，控制终端根据预设第一更新周期或者随机向所述云服务器发送加密算法更新请求；In this embodiment, when the control terminal sends a control command to the smart home device to be controlled, the encryption algorithm of the smart home system is dynamically updated. If the mode is dynamically updated, the control terminal sends the encryption algorithm to the cloud server. When the request is updated, the control terminal sends an encryption algorithm update request to the cloud server according to a preset first update period or randomly;

在本实施例中，在由控制终端向待控制的智能家居设备发送控制指令的情况下，对智能家居系统的加密算法进行动态更新，若采用方式二进行动态更新，控制终端接收云服务器下发的加密算法更新指令时，接收云服务器根据预设第二更新周期或者随机或者是检测到控制指令异常时下发的加密算法更新指令。In this embodiment, when the control terminal sends a control command to the smart home device to be controlled, the encryption algorithm of the smart home system is dynamically updated. If the dynamic update is performed in the second mode, the control terminal receives the cloud server. When the encryption algorithm updates the instruction, the receiving cloud server updates the instruction according to the preset second update period or randomly or when the control instruction is abnormal.

应当理解的是第一更新周期、第二更新周期可以是每隔一周、每隔半个月、每隔一个月等，具体情况具体分析，可以根据环境要求选择合适的周期。检测到控制指令异常是指检测到控制指令格式不对，或者在短时间内连续收到N次相同的控制指令，这表明黑客可能正在尝试破解，表明异常。N可以根据经验取一个合适的数值。It should be understood that the first update period and the second update period may be every other week, every half month, every other month, etc., and the specific case may be analyzed, and an appropriate period may be selected according to environmental requirements. Detecting a control command exception means that the control command format is detected incorrectly, or in a short time.The same control command is received N times in succession, which indicates that the hacker may be trying to crack, indicating an exception. N can take a suitable value based on experience.

实施例二：Embodiment 2:

参见图2所示，本实施例提供一种智能家居系统的解密控制方法，包括：As shown in FIG. 2, the embodiment provides a decryption control method for a smart home system, including:

S201：智能家居设备接收控制指令；S201: The smart home device receives the control instruction;

S202：智能家居设备获取自身当前的解密算法；解密算法与控制指令进行加密时采用的加密算法对应，且解密算法与智能家居系统中的其他至少一个智能家居设备当前的解密算法不同；S202: the smart home device obtains its current decryption algorithm; the decryption algorithm corresponds to an encryption algorithm used when the control instruction performs encryption, and the decryption algorithm is different from the current decryption algorithm of at least one other smart home device in the smart home system;

S203：智能家居设备根据解密算法对控制指令进行解密。S203: The smart home device decrypts the control instruction according to the decryption algorithm.

应当理解的是解密算法与所述智能家居系统中的其他至少一个智能家居设备当前的解密算法不同，包括解密算法与所述智能家居系统中的其他各智能家居设备当前的解密算法都不同，例如，如表六所示：It should be understood that the decryption algorithm is different from the current decryption algorithm of at least one other smart home device in the smart home system, including the decryption algorithm being different from the current decryption algorithms of other smart home devices in the smart home system, for example, As shown in Table 6:

表六Table 6

智能家居Smart home空调air conditioning电视TV洗衣机washing machine冰箱refrigerator……......解密算法Decryption algorithm解密算法ADecryption algorithm A解密算法BDecryption algorithm B解密算法CDecryption algorithm C解密算法DDecryption algorithm D……......

本实施例中的表可以由智能家居系统开发商在控制端与智能家居设备端内预置，也支持用户自定义设置，且可同步到云服务器侧。The table in this embodiment can be preset by the smart home system developer in the control terminal and the smart home device end, and also supports user-defined settings, and can be synchronized to the cloud server side.

本实施例中的解密算法与对所述控制指令进行加密时采用的加密算法对应，当加密算法采用加密映射表时，对应的解密算法采用解密映射表。解密映射表中包含待解密字符与解密符的对应关系，这种对应关系与加密映射表中的对应关系相同，可以是预先设定的一种随机对应关系，也可以是预先设定的一种遵循某种规律的对应关系。智能家居设备获取自身当前的解密算法，如果获取到的解密算法为解密映射表，就会通过将控制指令中的待解密字符根据待解密字符与解密符的映射关系全部映射成解密符的方式对控制指令进行解密。The decryption algorithm in this embodiment corresponds to an encryption algorithm used when encrypting the control instruction. When the encryption algorithm uses an encryption mapping table, the corresponding decryption algorithm uses a decryption mapping table. The decryption mapping table includes a correspondence between the character to be decrypted and the decryption symbol, and the correspondence relationship is the same as the corresponding relationship in the encryption mapping table, and may be a preset random correspondence relationship, or may be a preset one. Follow a certain law of correspondence. The smart home device obtains its current decryption algorithm. If the obtained decryption algorithm is a decryption mapping table, the character to be decrypted in the control instruction is mapped to the decryption symbol according to the mapping relationship between the character to be decrypted and the decrypted character. Control instructions are decrypted.

为了更好的理解本发明，下面用解密映射表对控制指令进行解密作进一步说明。例如，预先设定的加密映射表的一部分如上面表三所示，则对应的解密映射表的一部分如表七所示：For a better understanding of the present invention, the decryption mapping table is used to decrypt the control instructions for further explanation. For example, a part of the preset encryption mapping table is as shown in Table 3 above, and a part of the corresponding decryption mapping table is as shown in Table 7:

表七Table 7

若智能家居设备接收到的控制指令为“vb43Rvf.fgdsfgRFASASSsd”，则根据待解密字符与解密符的对应关系，解密后得到的实际传送的控制指令是“35hjyCDIGJ”。If the control command received by the smart home device is "vb43Rvf.fgdsfgRFASASSsd", the actual transmitted control command obtained after decryption is "35hjyCDIGJ" according to the correspondence between the character to be decrypted and the decrypted character.

应当理解的是，本实施例中智能家居系统的解密算法与控制指令进行加密时采用的加密算法对应，因此为了进一步提高智能家居系统的安全性，智能家居系统的解密算法还可以通过以下方式进行动态更新：智能家居设备接收解密算法更新指令，解密算法更新指令中包含新的解密算法；智能家居设备将本地当前的解密算法更新为新的解密算法。It should be understood that the decryption algorithm of the smart home system in this embodiment corresponds to the encryption algorithm used when the control command is encrypted. Therefore, in order to further improve the security of the smart home system, the decryption algorithm of the smart home system can also be performed in the following manner. Dynamic update: the smart home device receives the decryption algorithm update instruction, and the decryption algorithm update instruction includes a new decryption algorithm;The home device updates the local current decryption algorithm to a new decryption algorithm.

应当理解的是，解密算法的动态更新应当与控制指令采用的加密算法的动态更新对应，也即是当加密算法动态更新时，相应的解密算法也应当动态更新。本实施例中，动态更新时，可以对系统中的某一个或部分多个家居设备的解密算法进行更新，也可以对系统中所有的家居设备对应的解密算法进行更新，相应的这种更新可以是各家居设备所采用的各不同解密算法的互相交换，也可以是新的解密算法对原有的解密算法的替换。It should be understood that the dynamic update of the decryption algorithm should correspond to the dynamic update of the encryption algorithm employed by the control instruction, that is, when the encryption algorithm is dynamically updated, the corresponding decryption algorithm should also be dynamically updated. In this embodiment, when the dynamic update is performed, the decryption algorithm of one or a part of the plurality of home devices in the system may be updated, and the decryption algorithm corresponding to all the home devices in the system may be updated, and the corresponding update may be performed.

若更新后的设备与解密算法对应关系表与原设备与解密算法对应关系表中的部分智能家居设备与解密算法的对应关系相同，则更新后的设备与解密算法对应关系可以如下表九所示：If the correspondence between the updated device and the decryption algorithm correspondence table is the same as the correspondence between the smart device and the decryption algorithm in the correspondence between the original device and the decryption algorithm, the correspondence between the updated device and the decryption algorithm may be as shown in Table IX. :

If the cloud server requests the active update decryption algorithm, the smart home device receives the decryption algorithm update command sent by the cloud server, and the receiving cloud server according to the preset second. The update period is either random or a decryption algorithm update instruction sent when the control instruction is abnormal. The decryption algorithm update instruction may also be directly sent by the user through the cloud server.

应当理解的是第一更新周期、第二更新周期可以是人为设定的任意一个时间间隔，例如可以是一天、一周等，具体情况具体分析，可以根据环境要求选择一个合适的周期。所称检测到控制指令异常可以是检测到控制指令格式不对，或者在短时间内连续收到多次相同的控制指令，这表明他人可能正在尝试破解，智能家居系统存在的被攻击的可能性较高。It should be understood that the first update period and the second update period may be any one of the artificially set time intervals, for example, one day, one week, etc., and the specific case may be analyzed, and an appropriate period may be selected according to environmental requirements. The so-called detection of the control command abnormality may be that the control command format is detected incorrectly, or the same control command is continuously received multiple times in a short time, which indicates that others may be trying to crack, and the possibility of being attacked by the smart home system is more likely. high.

The so-called detection of the control command abnormality means that the control command format is detected to be incorrect, or the same control command is continuously received multiple times within a prescribed time, which indicates that the system is abnormal, and others may be cracking the system. For example, it may be that the same control command is received 10 times in a day, which indicates that the hacker is cracking.

When dynamically updating, the cloud server randomly determines a new encryption and decryption algorithm by comparing the original encryption and decryption algorithm, and then sends the encryption algorithm update instruction to the control terminal, and the encryption algorithm update instruction includes a new device and encryption algorithm correspondence table. At the same time, the update instruction of the decryption algorithm determined by the encryption algorithm is sent to the corresponding smart home device that needs to update the decryption algorithm. If the correspondence between the device and the encryption/decryption algorithm correspondence table is all updated, it can be as shown in the following Table XIV:
