Abstract

The invention discloses an access control authority identification method and device. The method and device are used for an access control terminal. The method comprises, through a private key in a key pair produced in a SAM card, carrying out signing on a first random number transmitted by a user card and verifying a digital certificate and a signature of the user card through a certification authority root certificate in the SAM card. The private key cannot be read and the certification authority root certificate is not easily tampered so that access control system safety is improved.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control authentication method and device. Background technique [0002] At present, the access control card is a card used in the access control system, such as the access card, access control card, parking card, membership card, etc., through the system administrator setting, the usable area and user rights are determined, and the user uses the access control card to enter the management area, thereby To achieve a safety management role. [0003] In the prior art, about 80% of the access control cards in my country use Identification Cards (ID cards for short) or M1 cards (abbreviations for chips produced by NXP, a subsidiary of Philips, and the full name is NXP Mifare1 series). The only identifier (unique identifier, referred to as: UID), and a little more advanced is to use the sectors of the M1 card for data operations, using the independent key of each secto...
