Agent技术的研究起源于人工智能领域。由于Agent具有自治性、智能性、反应性、主动性等优点，因此越来越受到人们的重视，并被广泛应用于网络技术和分布式计算。Agent技术很好的解决了网络间任务分配及合作的问题，但Agent系统实际应用时的安全问题一直没有得到很好的解决。本文设计了一个可实际应用的Mobile Agent系统安全问题解决方案，该方案可以有效解决实际运行中Agent系统的安全认证及安全通信问题。最后介绍了该方案在个性化E-learning系统中的实际应用情况。-Agent technology research originated in the field of artificial intelligence. As Agent with autonomy, intelligence, response, the advantages of the initiative, attracting increasing attention, widely used in network technology and distributed computing. Agent good solution to the network and the distribution of tasks between the issue of cooperation, but Agent System practical application of the safety problem has never been satisfactorily resolved. This paper is designed to be a practical application of the Mobile Agent System security solutions, The program can effectively resolve the practical operation of the safety system Agent certification and safety communications. The final presentation of the Program in Personalized E-learning system of practical application.
