摘　　要：访问控制技术是防止非法用户进入系统和合法用户对系统资源的非法访问。它尤其在操作系统层面上给主机提供一种安全机制,确保那些认证用户对资源的访问。在P2P(对等网络)中由于缺少集中管理使得访问控制的实现更具有挑战性。在本文中,我们将在一个P2P环境中讨论访问控制机制,并且描述其在基于JXTA的P2P框架下的实现。JXTA是一个流行的开放式的P2P技术规范。Access control technology prevents illegal user＇ s entry into the system and legitimate users illegally access to system resources. Typically, Access control is provided as a security mechanism for a host at the operating system level. This ensures that authenticated users have access to resources based on their assigned roles. Access control is more challenging in Peer-to-Peer （P2P） systems, due to the lack of centralized administration. In this paper we discuss access control over a P2P network and we present an access control implementation in the JXTA P2P framework. JXTA is a popular open P2P technology specification.
