移动Agent系统安全技术研究

移动Agent作为新一代网络分布处理技术，能在网路上任意移动，自动执行使用者所设计和赋予的工作任务。移动Agent的安全问题是该项技术能否成功应用的关键。对移动Agent可能存在的安全问题以及遭受的攻击类型作了较详细的论述。从检测和保护两方面来阐述目前解决移动Agent安全问题的方法以及存在的问题。最后，引入具有监控和授权功能的安全管理器，提出了一种新的移动Agent系统安全模型，并分析了该模型的整个工作流程。

Study of Securrty Technique about Mobile Agent System

Mobile Agent which is as the new generation network distribution processing technology can move randomly in the network, and can execute the task which is designed by user. The security problem of mobile agent is key whether this technology can be applied successfully or not. The security problem and the attack types of mobile agent is detailed in this paper; then, we aralyze the methods of dealing with the secunity problem and existence problem from the monitor and protection at present. Lastly, introducing the security management which can provide monitor and authorization functions, a new security model about mobile agent system is presented, and the full workflow is analyzed.
