Research Of Distributed Privilege Management

At present, development of network and information make people more and more depend on network. But complicated network frame, extensive application services and sensitive information not only require us to implement identity authentication , but also to control and validate privilege. And that, existing authorization technologies have much limitation, can't satisfy our demand, so we must bring forward a new privilege management system.This paper focues on distributed privilege management.First, it analyzes PMI and existing technologies. Second, with PKI and RBAC, it puts forward a kind of distributed privilege management project. In this project, local privilege management center answers for the defines of local roles and privilege management of roles and users, remote privilege management centers answer for privilege management of remote roles, thus to reach the object of accessing the resources on network.At last, it implements a small privilege management archetype system.
