Dynamic password intelligent unlocking system and method

Abstract

The invention relates to a dynamic password intelligent unlocking system, which comprises a user terminal, an intelligent lock and a dynamic password server. The user terminal comprises a display module, a processing module I, a communication module I and a storage module 1, the intelligent lock comprises a processing module II, a communication module II and a storage module II, the dynamic password server comprises a processing module III, a communication module III and a storage module III. The invention also relates to a dynamic password intelligent unlocking method, and the method respectively generates password corresponding to the user terminal and the intelligent lock. By using the generated dynamic password method and the corresponding dynamic password of the invention, the password does not need to be replaced frequently, the calculation method for updating the password is simple and convenient, and if the dynamic password is stolen in the transmission process, the real dynamic password content cannot be obtained because the calculation and conversion rules cannot be obtained, so that the security of authentication and transmission is improved.

Description

technical field [0001] The invention relates to the field of dynamic password electronic locks, in particular to a dynamic password intelligent unlocking system and method. Background technique [0002] With the development of network and intelligent technology, ordinary locks have also developed into intelligent electronic locks. 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. The password in the electronic lock is also the main means of unlocking. [0003] The passwords used in electronic combination locks mainly include the following types: a fixed password preset for the user, the password is stored in a non-volatile memory, and the user enters the password every time the user needs to unlock, the input fixed password and the preset password The stored password is matched, if the match is suc...

Problems solved by technology

However, the disadvantage of this authentication method is: since the customer's account number is a fixed combination of numbers and letters or one of them, and the password is static, the customer will not modify it for a long time, and it is easy to forget if it is modified repeatedly

[0008] At the same time, the existing electronic combination locks also have the following disadvantages: single password, unconcealed operation, and easy t
