【摘要】 移动Agent作为分布式网络计算的一种新形式,可以降低网络传输量,异步地完成任务。但在复杂的网络环境下,移动Agent对安全性提出了特殊的要求。文中先大致介绍了移动Agent所带来的安全隐患,然后深入地研究了Java语言的安全机制,最后给出了一个安全模型的参考实现,并讨论如何结合Java的安全模型来解决移动Agent的安全性问题。虽然Java的安全模型本身存在一些不完善的地方,但随着其进一步改进,安全模型参考实现也将为移动Agent的应用提供更有力的保障。更多还原

【Abstract】 As a new form of distributed network computing,mobile agent can reduce the network transmission and accomplish the tasks asynchronously. But in the complicated network environment,it puts forward special requests to the security.Briefly introduces those hidden secure troubles brought by mobile agent,and then studies the security mechanism of Java language,finally it gives a reference realization of security model and discusses how to solve the security problem with the help of Java.There exist some imperfect places in Java, but with the ceaseless improvement, our reference realization of security model will provide more powerful safeguard to the applications of mobile agent.更多还原
