Coordinate access control system of ternary structure

The present invention relates to a structure of the security implementation ternary mutual authentication terminal and the network access control system and the like, an authentication method provided in the access controller layer three entity prior two yuan structure, layers having the authentication method the authentication credential for authentication function entity three ternary structure is formed, so that the terminal, the access controller and the authentication server are involved directly disposable build trust between the terminal and the access controller; system of the present invention not only solves 2.20 entity existing access control system architecture flexibility in the form of restricted access, access controller should expand the number of technical issues, but also solve the existing dual unit triple-entity structure of the access control system Trusts the process of building complex and technical issues affecting network security, the independence of the advantages of high safety performance, without changing the existing network architecture, authentication protocol with a relative.
