p2p网络自服务访问控制协议设计

Self-service Acess Control Protocol of p2p Network

纯分散式p2p(peer-to-peer)网络中没有中心服务器,网络的各种安全服务由网络组内节点联合完成。本文研究了应用门限密码学方法实现p2p网络访问控制服务的问题。在分析前人访问控制协议安全漏洞基础上,以门限签名机制为核心,设计了由一系列安全门限运算协议构成的多方参与p2p网络自服务访问控制协议。整个协议过程不需要中心服务器参与。文章分析了协议的安全性、鲁棒性和效率。

In fully distributed peer-to-peer systems,secure services have to be fulfilled by the union of peer-group members because there is no centralized authority.This paper investigates the application of threshold cryptography for membership control in p2p system .We analyze the secure flaws in prior works and design a multi-party self-service p2p access control protocol on the basis of threshold computation protocols.No centralized authority is needed through the whole protocol process.The analysis of security,robust and efficiency is provided.
