摘　　要：提出一种可信片上Agent模型(T-AoC),它用于开放的、不安全的、面向网络边缘节点的对等网络环境中。为了有效保护应用Agent计算的系统中的Agent不被恶意Agent执行环境及Peer主机对Agent的攻击,T-AoC模型采用集成芯片作为硬件基础为Agent提供安全、可靠的执行环境。该芯片可安装在各需要运行Agent及其应用系统的对等网络节点主机上。基于信任关系转移的思想,增强对等网络节点之间的可信性,更有效地构建各种安全、可靠的基于Agent的P2P应用系统。具体描述了T-AoC模型的层次架构、工作原理和运行流程,以及T-AoC在P2P网络信息搜索系统的应用示范,分析了T-AoC的性能特点。A Trusted Agent-on-Chip model（T-AoC） is presented in this paper,which could be used in open,insecure Peer-to-Peer network computing environment make up of edge nodes of Internet.In order to effectively protect Agents in the Agent application systems from attacks of malicious Agent execution environments and hosts,T-AoC model adopts the integrated chip as the hardware foundation to provide a safe and reliable execution environment for Agent.The chip can be installed in the host of peers needing to run Agent-based systems.Based on the idea of trust relation transfer,the credibility of peer is enhanced,and it is more efficient to build a variety of safe and reliable Agent-based P2P applications. This paper describes the architecture,working principle and operation process of T-AoC model in detail,as well as how to deploy T-AoC in the P2P network information search system demo.The performance analysis of T-AoC is presented at the end of this paper.
