Encryption is carried out to the communication data in data packet before the communication data packet, to prevent data from being cut in transmission process
It obtains and causes leakage of data.The communication data packet received is transmitted to described by the communication module 5 of safety intelligent lock
Security module 4, the security module 4 carries out data encapsulation process again after the received communication data packet is decrypted,
Then the new communication data packet of generation is transmitted to the central control module 1, the central control module 1 is receiving newly
Communication data packet after send a customer identification information to the memory module 2 and read signal, the memory module 2 will be pre-stored in
Interior user information is sent to the security module 4 by way of data packet, and the security module 4 is equally to from institute
The data packet for stating memory module 2 is decrypted and is sent to the central control module 1, the central control module after encapsulating again
1 pair of customer identification information from the communication module 5 and the user information from the memory module 2 carry out data ratio
Right, if user identity compares successfully, the central control module 1 sends a unlocking signal, institute to the locking bolt control module 3
State locking bolt control module 3 based on the received unlocking signal control locking bolt driving part 10 unlock, if comparison is unsuccessful, it is described in
Entreat control module 1 by the communication module 5 to remote terminal transmission unlocking failure signal, and/or to being set to the safety
The alarming device such as indicator light 11 and/or loudspeaker 12 on smart lock lock body send alarm signal, to remind user
It unlocks and fails.
The present invention, can be to the user being stored in safety intelligent lock by adding security module inside safety intelligent lock
The communication data of identification information and the safety intelligent lock is encrypted, and attacker can not obtain user information easily, is reduced
The risk of illegal unlock improves the security level of safety intelligent lock.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
It encloses, to those skilled in the art, should can appreciate that all with made by description of the invention and diagramatic content
