Abstract

The invention discloses a dynamic password-based electronic lock system and authentication method thereof. The dynamic password-based electronic lock system comprises an electronic lock and a dynamic token, wherein the dynamic token comprises a clock module, a dynamic password generation module, a display module and a power module; the electronic lock comprises a clock module, a password generation module, a control module and a power module; the dynamic password generation module and the password generation module are in time synchronization; the dynamic password generation module is used for generating the dynamic password according to the current time information of the clock module of the dynamic token; and the password generation module is used for generating a group of dynamic passwords according to the time information within the current time vicinity of the clock module of the electronic lock. According to the invention, the safety, the irrepeatability and the randomness of the password of the electronic lock can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of anti-theft electronic locks, in particular to an electronic lock system based on a dynamic password and an authentication method thereof. Background technique [0002] With the development of electronic technology, various electronic products emerge at the historic moment, and electronic lock is one of them. There are many types of electronic locks, such as digital locks, fingerprint locks, magnetic card locks, IC card locks, biometric locks, etc. What is more widely used at present is still a key-type electronic combination lock. [0003] Electronic combination lock is a product that controls the operation of circuits or chips through password input, thereby controlling the opening and closing of mechanical switches, and completing the tasks of unlocking and locking. It has the following advantages: simple operation, easy to learn; intrusion sensing function, when the door is locked, when someone break...
