Abstract

The invention discloses a distributed access control model and access method. The access control subject sends access request information, and the neighbor nodes of the access control subject judge whether they are the access control object according to the access request information; if so, judge the access control subject's Whether the access request complies with its own access control strategy, if so, provide corresponding access content and operations; The control strategy judges whether the access control subject in this access request has permission to access the access control object in this access request; if it has permission, it forwards the access request to its neighbor nodes and repeats the above operations; if not, then Return a rejection message. The access control strategy of the present invention adopts a distributed management method, so that each node in the network that has an access relationship with it jointly manages the access control strategy of the entire network.
