Abstract

The present invention provides a digital certificate control method of access control system, the control master transmits a random code to USB Key when the USB Key is connected to the interface circuit, the USB Key uses inner key encryption to generate cryptograph and transmits to the control master, the control master USB Key of the digital certificate and decoding the received cryptograph to cleartext, the control master compares the cleartext with the random code, when the comparing result is identical, the indentity of USB Key holder is determined; the control master transmits opening command to open lock mechanism after determining legal identity and access permision of the holder, when USB Key breaks the connection with the interface circuit, the control master transmits closing command, the locking mechanism is closed. The invention also provides an access control system applying the above method, including an access control system, an inner key, a digital certificate and a USB Key of digital signature and a locking mechanism. The access control method and system of the invention has convenience, high security and high credibility.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to a digital authentication control method of an access control system. The invention also relates to an access control system applying the digital authentication control method. technical background [0002] The general access control system in the prior art is made up of several parts: feature carrier, reading device, control circuit, control host, locking mechanism and connecting lines between them. The technology of the access control system is mainly manifested in the feature carrier and how the feature carrier communicates with the reading device. [0003] As a system for controlling and managing personnel access, the access control system must first confirm the identity of the personnel entering and exiting to determine whether they have permission to pass. This requires a method to give the logo of the identity and authority of the access personnel, and this logo is...
