背景技术Background technique

近年来，在国家政策扶持下，人工智能技术快速发展，消费者在智能家居领域的消费需求激增，整个智能家居行业也正在快速发展和渗透。其中，智能门锁作为智能家居的入口级产品，以及家庭智能安防产品的重要组成，已经逐渐成为智能家居产业链的重要一环。In recent years, with the support of national policies, artificial intelligence technology has developed rapidly, consumers' consumption demand in the field of smart home has surged, and the entire smart home industry is also developing and penetrating rapidly. Among them, smart door locks, as an entry-level product for smart homes and an important component of home smart security products, have gradually become an important part of the smart home industry chain.

目前，智能门锁应用技术主要包括三方面：在安全开锁技术应用方面，普遍应用指纹识别、人脸识别、密码、手机app以及智能卡等安全级别相对较高的开锁技术；在平台连接方面，随着应用场景的拓展，蓝牙、zigbee、wifi、NB以及lora等物联技术都在智能门锁上有应用；智能化和人性化方面，报警提醒，防撬提醒，亲情提醒等功能可以为用户提供更多的智能化和个性化服务。At present, the application technology of smart door lock mainly includes three aspects: in the application of security unlocking technology, fingerprint recognition, face recognition, password, mobile phone app and smart card and other unlocking technologies with relatively high security levels are widely used; in terms of platform connection, With the expansion of application scenarios, IoT technologies such as Bluetooth, zigbee, wifi, NB, and lora are all applied to smart door locks; in terms of intelligence and humanization, functions such as alarm reminders, tamper-resistant reminders, and family reminders can provide users with More intelligent and personalized services.

在整体应用技术中，开锁涉及的安全技术无疑是考量智能门锁的一个最重要的指标。智能门锁普遍应用指纹识别，人脸识别、密码、手机app、智能卡等开锁技术，但是无论指纹识别、人脸识别这种应用生物识别技术的开锁方式，还是通过手机app、密码或者智能卡开锁的方式都存在明显的缺点。例如，生物识别存在功耗问题，成本问题，生物识别信息造假以及在使用过程中经常的采集困难等。而手机app、密码和智能卡存在安全性问题和使用便捷性问题。In the overall application technology, the security technology involved in unlocking is undoubtedly the most important indicator for considering smart door locks. Smart door locks generally use fingerprint recognition, face recognition, passwords, mobile apps, smart cards and other unlocking technologies, but regardless of fingerprint recognition, face recognition, which uses biometric technology to unlock the lock, it is still unlocked through mobile app, password or smart card Both methods have obvious disadvantages. For example, biometric identification has problems of power consumption, cost, fraudulent biometric information, and frequent collection difficulties during use. However, mobile apps, passwords, and smart cards have security and usability issues.

图5是根据本申请实施例的实现安全无感开锁系统的示意图。如图5所示，当用户携带安装了蓝牙SIM密码卡智能终端靠近智能门锁时，智能门锁首先通过其中的人体感应模块判断用于在靠近，智能门锁启动蓝牙定位阵列天线用于判断智能终端内的蓝牙SIM密码卡的位置是否足够接近并且处于门外，当蓝牙SIM密码卡处于设定范围(例如，0.5～1米)外或门内时，关闭蓝牙定位阵列天线；当蓝牙SIM密码卡处于设定范围内且在门外时，建立智能门锁与蓝牙SIM密码卡的蓝牙连接，启动智能门锁与蓝牙SIM密码卡的认证。在图5所示的实施例中，蓝牙定位阵列天线为高精度蓝牙定位阵列天线。Fig. 5 is a schematic diagram of a system for realizing safe and non-inductive unlocking according to an embodiment of the present application. As shown in Figure 5, when the user carries a smart terminal installed with a Bluetooth SIM password card and approaches the smart door lock, the smart door lock first judges the proximity through the human body sensing module, and the smart door lock starts the Bluetooth positioning array antenna for judging Whether the location of the Bluetooth SIM password card in the smart terminal is close enough and outside the door, when the Bluetooth SIM password card is outside the set range (for example, 0.5 to 1 meter) or inside the door, turn off the Bluetooth positioning array antenna; when the Bluetooth SIM When the password card is within the set range and outside the door, a Bluetooth connection between the smart door lock and the Bluetooth SIM password card is established, and the authentication of the smart door lock and the Bluetooth SIM password card is started. In the embodiment shown in FIG. 5 , the Bluetooth positioning array antenna is a high-precision Bluetooth positioning array antenna.

当蓝牙SIM密码卡的认证通过(即蓝牙SIM密码卡合法)时，智能门锁触发后续的开锁逻辑；而当蓝牙SIM密码卡的认证没有通过(即蓝牙SIM密码卡不合法)时，智能门锁不会触发开锁逻辑，门继续保持锁定状态。When the authentication of the Bluetooth SIM password card is passed (that is, the Bluetooth SIM password card is legal), the smart door lock triggers the subsequent unlocking logic; The lock does not trigger the unlock logic and the door remains locked.

对于通过蓝牙定位阵列天线定位蓝牙SIM密码卡所处位置，图6是根据本申请实施例的通过蓝牙定位阵列天线定位蓝牙SIM密码卡所处位置的示意图。如图6所示，蓝牙定位阵列天线包括多个蓝牙定位天线，分别用于接收蓝牙SIM密码卡的广播信号。蓝牙定位天线对接收到的特定广播信号进行测量，分别计算出信号的高度角和方向角，并将结果反馈给智能门锁的主控制器。智能门锁的主控制器根据各个蓝牙定位天线采集的高度角和方向角，计算出蓝牙SIM密码卡的位置，即蓝牙SIM密码卡与智能门锁的距离以及处于门内还是门外。For locating the location of the Bluetooth SIM password card through the Bluetooth positioning array antenna, FIG. 6 is a schematic diagram of locating the location of the Bluetooth SIM password card through the Bluetooth positioning array antenna according to an embodiment of the present application. As shown in FIG. 6 , the Bluetooth positioning array antenna includes a plurality of Bluetooth positioning antennas, which are respectively used to receive broadcast signals of the Bluetooth SIM password card. The Bluetooth positioning antenna measures the specific broadcast signal received, calculates the elevation angle and direction angle of the signal, and feeds back the results to the main controller of the smart door lock. The main controller of the smart door lock calculates the position of the Bluetooth SIM code card according to the altitude angle and direction angle collected by each Bluetooth positioning antenna, that is, the distance between the Bluetooth SIM code card and the smart door lock and whether it is inside or outside the door.

对于智能门锁与蓝牙SIM密码卡的认证流程，图7是根据本申请实施例的智能门锁与蓝牙SIM密码卡的认证流程图。如图7所示，该流程包括如下步骤。Regarding the authentication flow of the smart door lock and the Bluetooth SIM password card, FIG. 7 is a flowchart of the authentication of the smart door lock and the Bluetooth SIM password card according to an embodiment of the present application. As shown in Figure 7, the process includes the following steps.

(1)智能门锁与蓝牙SIM密码卡建立蓝牙连接。(1) The smart door lock establishes a Bluetooth connection with the Bluetooth SIM code card.

(2)智能门锁终端生成并发送第一随机数给蓝牙SIM密码卡，其中该第一随机数可以是任意长度的随机数，例如可以是两字节的随机数。(2) The smart door lock terminal generates and sends a first random number to the Bluetooth SIM password card, wherein the first random number may be a random number of any length, for example, a two-byte random number.

(3)蓝牙SIM密码卡端建立连接后，可以延时等待100ms后，向智能门锁终端发送加密数据和蓝牙SIM密码卡生成的第二随机数。其中，加密数据生成过程可以是：使用蓝牙SIM密码卡安全芯片中保存的密钥将广播配置参数中的选定数据部分和智能门锁发送的第一随机数进行加密。(3) After the Bluetooth SIM password card terminal establishes a connection, it can wait for 100ms after a delay, and then send the encrypted data and the second random number generated by the Bluetooth SIM password card to the smart door lock terminal. Wherein, the encrypted data generating process may be: using the key stored in the security chip of the Bluetooth SIM password card to encrypt the selected data part in the broadcast configuration parameters and the first random number sent by the smart door lock.

其中，进行加密的密钥可以通过广播配置参数生成，例如，将广播配置参数的后四字节重复3次，然后补四字节0组成16字节长度的密钥。广播配置参数中的选定数据部分可以是广播配置参数后7字节数据。还可以要求加密数据需能被16整除，对不能整除的数据进行补齐，例如，补齐数据的第1个字节为0x80，第2～n字节均为0x00，加密算法可以采用3DES-ECB模式。Wherein, the encryption key can be generated through broadcast configuration parameters, for example, the last four bytes of the broadcast configuration parameters are repeated three times, and then four bytes of 0 are added to form a 16-byte key. The selected data part in the broadcast configuration parameter may be 7-byte data after the broadcast configuration parameter. You can also require that the encrypted data be divisible by 16, and fill in the data that is not divisible. For example, the first byte of the filled data is 0x80, and the second to n bytes are all 0x00. The encryption algorithm can use 3DES- ECB mode.

(4)智能门锁收到蓝牙SIM密码卡的加密数据以后，在完成数据解密，判断解密的明文数据和智能门锁中保存的广播配置参数、第一随机数是否一致。(4) After the smart door lock receives the encrypted data of the Bluetooth SIM password card, it completes the data decryption, and judges whether the decrypted plaintext data is consistent with the broadcast configuration parameters and the first random number saved in the smart door lock.

(5)如果解密的明文数据和智能门锁中保存的广播配置参数、第一随机数一致，智能门锁发送认证数据返回给蓝牙SIM密码卡认证数据生成过程。认证数据的生成过程包括：使用智能门锁安全芯片中保存的密钥，将广播配置参数中的选定数据部分和智能门锁发送的第二随机数进行加密。(5) If the decrypted plaintext data is consistent with the broadcast configuration parameters and the first random number stored in the smart door lock, the smart door lock sends the authentication data back to the Bluetooth SIM password card authentication data generation process. The process of generating the authentication data includes: using the key stored in the security chip of the smart door lock to encrypt the selected data part in the broadcast configuration parameters and the second random number sent by the smart door lock.

其中，其中该第二随机数可以是任意长度的随机数，例如可以是两字节的随机数。进行加密的密钥可以通过广播配置参数生成，例如，将广播配置参数的后四字节重复3次,然后补四字节0组成16字节长度的密钥。广播配置参数中的选定数据部分可以是广播配置参数后7字节数据。还可以要求加密数据需能被16整除，对不能整除的数据进行补齐，例如，补齐数据的第1个字节为0x80，第2～n字节均为0x00，加密算法可以采用3DES-ECB模式。一般要求加密数据的长度是16个字节的整数倍。例如，加密数据的长度是12个字节，通过增加一个0x80的字节和3个0x00的字节将其补齐到16个字节。再如，加密数据的长度是26个字节，通过增加一个0x80的字节和5个0x00的字节将其补齐到32个字节。Wherein, the second random number may be a random number of any length, for example, may be a two-byte random number. The encryption key can be generated through the broadcast configuration parameters, for example, repeat the last four bytes of the broadcast configuration parameters three times, and then add four bytes of 0 to form a 16-byte key. The selected data part in the broadcast configuration parameter may be 7-byte data after the broadcast configuration parameter. You can also require that the encrypted data be divisible by 16, and fill in the data that is not divisible. For example, the first byte of the filled data is 0x80, and the second to n bytes are all 0x00. The encryption algorithm can use 3DES- ECB mode. It is generally required that the length of encrypted data be an integer multiple of 16 bytes. For example, the length of encrypted data is 12 bytes, and it is padded to 16 bytes by adding a byte of 0x80 and three bytes of 0x00. For another example, the length of encrypted data is 26 bytes, and it is padded to 32 bytes by adding a byte of 0x80 and 5 bytes of 0x00.

可以理解的是，加密的密钥、广播配置参数中的选定数据部分、第一随机数和第二随机数的实现方式以及加密数据的补齐方式和加密算法的选定不限于上述实施例举出的方式，只要能够实现加密满足安全要求，本领域技术人员在上述实施例的启发下可以想到的其他实现方式都属于本申请覆盖的范围。It can be understood that the encryption key, the selected data part in the broadcast configuration parameters, the implementation of the first random number and the second random number, the complementing method of the encrypted data and the selection of the encryption algorithm are not limited to the above-mentioned embodiments As long as the enumerated manners can realize encryption and meet security requirements, other implementation manners that those skilled in the art can think of under the inspiration of the above-mentioned embodiments all fall within the scope covered by the present application.

(6)蓝牙SIM密码卡端接收认证数据，并使用自身安全芯片中存储的密钥进行解密，解密后的数据与自身存储的广播配置参数、第二随机数进行比对查看是否正确，如果通过则返回认证通过信息给智能门锁终端；其中，认证通过信息可以是代码E09000。(6) The Bluetooth SIM password card end receives the authentication data, and uses the key stored in its own security chip to decrypt, and compares the decrypted data with its own stored broadcast configuration parameters and the second random number to check whether it is correct. Then return the authentication passing information to the smart door lock terminal; wherein, the authentication passing information can be code E09000.
