Password unlocking method, device and system for smart lock

Abstract

The invention belongs to the technical field of smart locks, and provides a password unlocking method, device and system for a smart lock. The method comprises the following steps: acquiring a door lock serial number of a target smart lock and a Bluetooth physical address of a user mobile end; splicing the door lock serial number and the Bluetooth physical address to construct a fixed-length character string; encrypting the character string by adopting a 256-bit encryption algorithm to generate an encrypted key; generating a fixed number of groups of random sequences at a set moment; encrypting the random sequences by adopting the 256-bit encryption algorithm to generate a fixed number of groups of random keys; receiving an unlocking password transmitted by a user; and comparing the unlocking password with the encrypted key and / or the random keys: if the unlocking key is consistent with the encrypted key and / or the random keys, controlling the target smart lock to be unlocked. Through adoption of the password unlocking method, device and system for the smart lock, remote unlocking can be realized. Moreover, a complicated encryption algorithm is adopted, so that the security of the encrypted key and the random keys is enhanced.

Description

technical field [0001] The invention relates to the technical field of smart locks, in particular to a password unlocking method, device and system for smart locks. Background technique [0002] At present, smart locks are widely used to provide security for various businesses and residences. However, the encryption technology of most current smart locks is weak, such as the transmitted data is not encrypted or simply encrypted. In the long run, the password of the smart lock is easy to leak, or the password of the same series of smart locks is easy to crack, and even the smart lock password is transmitted during the transmission process. , It is easy to be intercepted and cracked by other software, which will cause certain security risks for businesses and various residences. [0003] In addition, most smart locks cannot realize the remote unlocking function, or the user cannot successfully realize the remote unlocking. [0004] How to use a password to open the smart loc...
