摘要
移动代理的安全是目前一大难题,学术界提出加密、身份认证、划分域等方法,但是这些方法的应用使得移动代理在执行任务时耗费大量时间,且存在安全问题.针对上述两个问题,本文使用模糊综合评判法对移动代理服务器各个属性进行综合评判,得出服务器的信誉值.该信誉值比现有域划分方法得出的结果更加精确,从而更精确地完成移动代理服务器域的初始化.经实验证明:本文提出的方法较现有的域初始化方法,可以缩短移动代理执行任务的时间,同时也提高了移动代理的安全性.
Recently the security of Mobile agent was still a very difficult problem. Solutions as encryption, authentication, and domain partition had been proposed. However, the application of these methods was time-consuming in running and safety problem as well. For the above two problems, fuzzy comprehensive evaluation method was used in this article to evaluate every attribute synthetically of the mobile agent server, and get the reputation value of the server. It was proved by the experiment that this method was better than the existing domain initialization method in time shorten and security when mobile agent tasks performing.
