Abstract

The embodiment of the invention discloses an entrance guard authentication method, which comprises the following steps that: a card reader judges whether private keys of the card reader and sub-keys specified by the card reader in an entrance guard card are successfully authenticated, wherein at least two sub-keys with a shared master key are stored in the entrance guard card; the card reader acquires data information which is required to be returned by the entrance guard card if the authentication is successful; and the card reader transmits the acquired data information to an entrance guard control terminal and receives authentication passing information returned after the entrance guard control terminal verifies the correctness of the data information. The embodiment of the invention also discloses an entrance guard authentication system. By the method and the system, the entrance guard card and a plurality of card readers are mutually authenticated; and therefore, nuclear power personnel using the entrance guard card can pass various nuclear power plants under the same nuclear power enterprise by using the same card.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control authentication method and an authentication system in the field of nuclear power access control. Background technique [0002] Nuclear energy is an important pillar of global energy development. With the development of nuclear power energy, its safety has become an important issue to be considered in the development process. [0003] At present, the method adopted by the nuclear power access control system is: to set up an independent access control system for each nuclear power plant area under the same enterprise, and the access control card of the nuclear power personnel only has an authorization key for the nuclear power plant area. When passing through the new nuclear power plant area outside the factory area, the authorization key of the original nuclear power plant area stored in the access control card needs to be cleared first, and then the auth...
