Method and system for generating and verifying dynamic passwords

Abstract

The invention relates to a system and method for generating and verifying dynamic passwords. A user terminal and an intelligent lock are connected through a wireless network; a dynamic password serveris respectively connected with the user terminal and the intelligent lock through the wireless network; the user terminal is used for providing application of unlocking and setting to users, and saving dynamic passwords and intelligent lock identification corresponding to the user terminal; the intelligent lock is used for controlling unlocking according to the unlocking information transmitted by the user terminal and control signals of the dynamic password server, and storing the dynamic passwords and intelligent lock identification corresponding to the intelligent lock; the dynamic password server is used for performing data interaction with the user terminal and controlling the intelligent lock to unlock. According to the system, the dynamic password generation process has a precise structure and is closely associated with the user terminal and the intelligent lock, so that the dynamic passwords cannot be easily cracked, the authorization security is improved, and meanwhile, operation load is no more increased.

Description

technical field [0001] The invention relates to the field of dynamic password electronic locks, in particular to a dynamic password generation and verification method and system. Background technique [0002] In the current environment, dynamic password technology is widely used in security fields such as finance and life, replacing the original static password and providing reliable protection for users' property security. In order to generate a dynamic password, the device that generates the dynamic password generally stores a preset password and a corresponding rule algorithm for internal calculation to obtain the required dynamic password. [0003] 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-typ...

AI Technical Summary

Problems solved by technology

[0009] However, the generation method of the dynamic password in the prior art is relatively simple, and has relatively low correlation with equipment such as user terminals or smart electronic locks, and is relatively easy to be cracked in the process of generation and use, thereby increasing the degree of risk, and the above-mentioned risks also directly affect The accuracy and security of the authentication are compromised, and it is easy to cause certain losses
