移动代理系统中可伸缩安全模型研究

随着移动代理(MA)使用范围的日益扩大，其安全性受到越来越多的关注。MA的安全性包括两方面：一是保护MA不受主机平台的攻击，二是保护主机平台不受恶意MA的攻击。现有的方法保护对具体的应用都有一定的局限。本文提出了一种基于策略的动态可伸缩安全模型，将MA与控制MA动作的策略进行分离，从而根据不同的需要对策略进行加载或卸载，从而达到对MA动态控制的目的。在本文的最后，对未来的工作提出了展望。

Research of the Flexible Security Modal of the Mobile Agent System

With the wide range use of the Mobile Agent(MA), the security of the MA is considered more seriously. The security of the MA includes two parts, protecting the mobile agent avoid-ing the attack of the host and protecting the host avoiding the at-tack of the malicious mobile agent. The way of the protecting now had some shortcoming. This paper put forward a new infrastruc-ture, in which the MA is separated from the policy which decides the actions of the MA. The applications could control agent be-havior by loading or unloading the policies. In the last paragraph, the future work was mentioned too.
