移动代理的安全性问题一直制约着移动代理的广泛应用。以往的研究主要集中在解决移动代理安全的一般问题,但随着移动设备的大量普及,移动代理技术应用于这些受限设备,其适用场合和安全问题应区别对待。本文首先讨论了在这些移动设备上的移动代理典型应用,然后阐述了相关的安全问题及解决办法。最后给出了一个基于J2ME的实现范例,并提供了一些实验结果。
The security of mobile agent is one of the key problems that restrict its wide use. The foregone studies mainly focus on solving the general problems of the mobile agent. But as the Mobile Device are used more and more popularly,when we adopt the mobile agent technology to these limited devices the suitable cases and security problems are different from the traditional use. In this paper, we firstly discuss the typical application in the Mobile Device, and then describe the related security problems and some possible countermeasures. Finally we give a sample implementation based on the J2ME platform and show some experimental results.
