中文摘要：

针对移动代理在异质网络环境中的安全问题,提出了一种代码迷乱转换保护策略.代码迷乱技术应用于移动代理,是对执行任务的移动代理的保护和隐藏模式的探索.该方案首先提出基于交叉循环迷乱和改变数据关联的移动代理保护策略,接着阐述了交叉循环迷乱、多模块交叉循环迷乱以及改变数据之间内在关联的具体方法.实验证明,该方案成功抵御了给定的7个java解码程序,显示出比多层退出迷乱和单层退出迷乱方法的有效性.

英文摘要：

Code obfuscation eneryption protecting scheme is put forward, aiming to solve the security problems ofMobile agents （MA） migrating across heterogeneous network execution environments. Code obfuscation technology is applied to MA, and MA codes of executing task will be hided and protected. Firstly, mobile agent protection scheme based on intersecting [oop obfuscation and varying data relationship is put forward in this paper. Secondly concrete methods of obfuscation protection scheme are introduced, and it is showed in experiment at last, 7 java decoders have been resisted using this scheme, which showed more validity than single--level exit obfuscation and multi--level exit obfuscation.
