本文提出一种基于C++语言程序的对抗不透明谓词和增加无效代码的代码迷惑变换算法．实验结果表明此算法具有较好的反代码迷惑效果．-This article proposed that one kind and increases the invalid code based on the C++ language procedure s resistance not transparent predicate the code to confuse the transformation algorithm. The experimental result indicated that this algorithm has the good counter-code to confuse the effect.
