摘要
由于P2P环境自身的分布性与匿名性等,传统的访问控制机制无法为P2P共享文件系统提供高效、安全的访问控制服务.为此,基于信任推荐机制与公平参与机制,提出了一种新的访问控制框架.这一框架能够在不改变P2P环境本身特性的条件下,实现高效文件访问控制服务.
Because the decentralized and anonymous characteristics of P2P （Peer- to - Peer） environments, the traditional access control mechanisms can＇t be used to provide a efficient and secure access controlling services for P2P sharing file system. Thus, based on the trust and recommendation mechanism and fair participation idea, this paper proposes a new access control framework. While preserving the special characteristics of the P2P sharing file system, this framework can implement the realistic and effective access control service.
