摘要
针对现有公开密钥基础设施(Public Key Infrastructure,PKI)在非集中不可信网络上部署的困境,提出了一种在对等(Peer to Peer,P2P)网络上部署分布式公钥密码体系的方法。首先,概述P2P网络中部署PKI面临的困难;其次,详细说明基于法定人数的分布式PKI系统的设计过程;最后,列举了该PKI系统应对各种攻击的表现,并对系统总体性能进行分析。
Aiming at the predicament of the existing PKI(Public Key Infrastructure)deployed on decentralized and untrusted networks,a method for deploying a distributed public key cryptosystem on a peer-to-peer(P2P)network is proposed.Firstly,the difficulty faced in deploying PKI in a P2P network is outlined,then,the design process of a distributed PKI system based on quorum expounded,and finally,the performance of the PKI system against various attacks cited.And the overall performance of this system is also analyzed.
