Entrance guard controlling method and system based on bidirectional authentication

Abstract

The invention provides an entrance guard controlling method and system based on bidirectional authentication. The core of the entrance guard controlling method and system is that a secure access module (SAM)-card safety module which is connected with an intelligent lock control system signal in an intelligent lock is added, can be embedded into the intelligent lock and be separated from the intelligent lock, and is used for storing a secret key and performing encryption / decryption operation. The SAM-card safety module is taken as a medium to realize the bidirectional authentication between a subscriber card and the intelligent lock, therefore, the safe authentication problem between a locket and the subscriber card in the entrance guard system is solved, the safety of the lockset is improved, the lockset or the subscriber card is prevented from being decrypted and cloned, the safety of data storage and data transmission is guaranteed, and further, the safety of the entrance guard system is guaranteed.

Description

technical field [0001] The invention relates to an access control method and system based on two-way authentication disclosed by the invention, which has the remarkable feature of high security. Background technique [0002] Existing access control methods mainly include: access control methods based on traditional M1 cards or common CPU cards; traditional door locks such as hotel locks. [0003] Access control systems based on traditional M1 cards or common CPU cards have security issues. Because the access control function is implemented by comparing the information in the user card read by the door lock with the data in the door lock, the data security cannot be guaranteed and it is easy to be cracked and cloned. Even if the data is encrypted and transmitted, it can only realize a simple one-way authentication function, that is, the smart lock authenticates the user card. Therefore, problems such as data leakage at the lock end and copying of the user card will still thr...

AI Technical Summary

Problems solved by technology

Even if the data is encrypted and transmitted, it can only realize a simple one-way authentication function, that is, the smart lock authenticates the user card. Therefore, problems such as data leakage at the lock end and copying of the user card will still threaten the security of the access control system. , users cannot safely use

[0004] However, the door lock of the traditional access control system has a simple structure, a single function, and poor security, which directly affects the security of the traditional access control system.
