【Abstract】 According to the security requirement of Peer-to-Peer (P2P) technology, this paper analyzes the advantages of current P2P access control strategy and proposes an efficient P2P clustering model. The model urity mechanism based on Rule Based Access Control (RBAC) as well as Java Authentication and Authorization vice (JAAS) are discussed, and the filter technology is also considered. Project application results show that AC technology is efficient for access control in P2P systems.更多还原
