【摘要】 P2P(Peer-to-Peer)技术得到了快速的发展和应用.针对P2P技术的应用特点,对Peer进行了定义,并对其属性进行了描述.建立了P2P应用的安全体系结构,提出了“一个核心、三个层次、四个接口”的体系结构,通过四个接口为P2P应用提供所需的安全服务,并对安全体系结构的层次关系进行了描述.该体系结构的建立能为P2P应用提供一个通用平台,通过该通用平台,实现对P2P应用系统中各类对象的统一描述,对用户进行鉴别,实现对各类对象的统一权限与授权管理,提供所需的安全服务,从而建立有序、可信的网络环境.更多还原

【Abstract】 As the techniques of P2P(Peer-to-Peer) get expeditious developments and applications,according to the application characteristics of P2P techniques,this thesis gives out the definition of peers,also describes the attributes of them.It establishes the security infrastructure of P2P applications,comes out with a infrastructure with "one core,three layers,four interfaces",so it can provides necessary security services for P2P applications through those four interfaces.And then the thesis describes the layer relationships of the security infrastructure.The establishment of the infrastructure can provide a common platform for P2P applications.This common platform can make universal descriptions of objects in P2P applications systems,make users authentication,implement the unification managements of authorization for all objects,and provide necessary security services.Consequently it can establish an orderable and reliable network environment.更多还原
