摘要

目前将信誉信息存储在本地进行管理的方法需要通过第三方验证信誉的完整性

这在动态的P2P环境中很难实现

而且信誉信息易丢失或被篡改.提出了一种新的本地存储信誉信息的管理方法

将信誉信息以证书的形式存储在本地

并由所有者自行维护.通过设计相应的协议

实现了旧信誉证书的完整性验证以及新信誉证书的生成.该方法避免了大量的通信开销

提高了查询效率

并具有一定的安全性.

Abstract

There are some methods to store reputation locally to improve efficiency

but it needs the third parties to avoid the information dropped or tampered by the peers themselves.It’s difficult to take it into reality in distributed Peer-to-Peer environments.We propose a novel protocol to store the reputation locally

which does not need the third parties.The reputation is stored in the certificates of the peers and maintained by themselves.The corresponding protocol realizes the integrity validation and creates the reputation certificates at the same process.This method can reduce communication overhead and improve the query efficiency.It’s also resistant to several of attacks.
