The intelligent door lock 5 encrypts the feedback message according to the predefined encryption seed to generate an encrypted data packet. After the encryption seeds are encrypted, the obtained data is 'A3D 30909B 96C CC 125E 961F 1203131311603316330B 5307852F FF'. The intelligent door lock 5 transmits the encrypted data packet to the device server 3. The encryption method has the advantages that the encryption seeds are strictly screened by combining the self protocol and the intelligent door lock resource design, so that the decryption difficulty is greatly increased; the data length cannot be changed after encryption and decryption, and the reliability of data transmission is improved; the encryption and decryption occupy less resources, the speed is high, and the energy consumption of the intelligent door lock is greatly reduced. In addition, through the above arrangement, after others steal data, the private protocol is cracked, the intelligent door lock 5 is controlled at will, others are prevented from monitoring, and the data is acquired for secondary use to achieve the purpose of controlling the intelligent door lock 5. Specifically, the encryption method of the scheme comprises the following steps: the encryption seeds with high decryption difficulty are strictly screened in advance and are respectively stored in the intelligent door lock 5 and the service program, and are not stored in the server or the memory of the intelligent door lock 5, so that the encryption seeds in the memory are prevented from being directly cracked and obtained; the server and the intelligent door lock 5 have the same encryption and decryption algorithms, and when a program receives or sends data, the program encrypts and decrypts the data to obtain correct data; in order to further enhance the difficulty of cracking, a special seed is defined in the encryption processing function, Unix time is used as the seed, a random function obtains the ID of the seed, and the uncertainty of encrypted data is increased; the seed ID, the data to be encrypted and the special seed are required to be encrypted, the encrypted data is obtained through a specific algorithm, the data decryption and the data encryption are reversible processes, and the original data can be obtained through the same processing of a decryption function.

The manager swipes the intelligent control card through the intelligent door lock 5, starts registration debugging, and triggers the intelligent door lock 5 to initiate a registration request. If the administrator swipes the smart card, the smart door lock 5 acquires the ID information of the smart card, and generates first door lock identity information, i.e., a first temporary MAC address. After the device server 3 receives the debugging instruction information, second door lock identity information, namely a database MAC address, is generated in a database (MySQL library) of the device server 3. And the intelligent door lock generates a registration packet according to the ID information of the intelligent control card and the first temporary MAC address, wherein the registration packet is a data packet. The intelligent door lock 5 sends a registration packet to all surrounding gateways 4 in a broadcast mode, and all gateways 4 receiving the registration packet send the registration packet to the equipment server 3.
