移动代理的安全问题研究是目前分布式计算安全研究的热点。如何有效的解决移动代理和宿主主机的安全、移动代理本身在网络传输中的安全和在不确定的目标主机上的安全、以及系统中实体间的安全交互是移动代理系统安全的关键问题。本文在针对移动代理系统环境安全分析的基础上，采用基于可信计算技术增强移动代理环境安全的方法，将可信计算平台和移动代理软件平台相结合方法，在可信硬件平台的基础上构建可信的移动代理平台，并通过可信链来增强信任传递；增强移动代理系统中的移动代理与主机身份认证，从而为移动代理与迁移宿主的安全交互提供增强的安全基础。

The research about the security of mobile agent is the hot spot of the distributed computing security. How to solve the problem about the security of the mobile agent and host, the transmit ting security of mobile agent on the network and its storing in uncertain target host, and the trusted communication between the entities in that environment are the critial problems. This paper analyses the the security of mobile agent system and uses the trusted computing technology to improve the security of the mobile agent system. In this paper the trusted platform and mobile agent software are combined to build the trusted mobile agent platform, the trusted link is used to transmit the trust and verify the identies of different mobile agents and platforms, thus the a improved security base is built for the dependable communication betwenn mobile agent and host platform.
