Peer-to-Peer系统信息匿名更新的研究与实现

Anonymous Updates in Peer-to-Peer System

在对P2P系统中的匿名性进行研究基础上,为P2P系统的底层结构设计了一个匿名结构.在这个结构中,存储节点可以被其他用户匿名更新.为更新进程设计了匿名“发布/查询”更新算法,然后从通信开销的角度,利用普通的分析模型对更新传播机制进行分析,证明其更新的连贯性.通过模拟实验给出了结果.

In today＇ s Peer - to - Peer system, data updates in peers are occurring frequently, the demand for anonymity is growing at an incredible rate. In this paper, the problem of updates in Peer - to - Peer system is studied, and an anonymous structure for the P2P infrastructure will be given. Storage peer in this structure can be updated by other peers by use of an anonymous tunnel, thus keeping anonymous between them. The basic function of our structure is its routing anonymity. An algorithm called “publish and query” will be given to pursue the updates routine. We use generic analytical model to investigate the utility of our update propagation scheme from the perspective of communication overhead, and prove that an important application of our update propagation method is consistency. At last, the simulation results are given. words： Peer - to - Peer computing ; anonymous updates
