基于程序设计类图保护的代码迷惑算法

Code Obfuscation Algorithm Based on Protecting Program Design Class Diagram

通过反向工程可以较容易获得Java程序代码的设计类图,从而给保护软件知识产权带来困难。为此,采用Java接口融合的代码迷惑方法,提出一种保护Java程序设计类图的代码迷惑算法,并根据该算法构造一种Java接口融合迷惑器。实验结果表明,该算法具有较好的迷惑效果,有效地隐藏程序的设计类图,并且没有额外时间消耗和大量冗余代码。

It is easy to get the design class diagram in Java application by applying reverse engineering, which makes it difficult to protect software intellectual property. This paper presents the code obfuscation techniques of protecting program design class diagram in Java application by applying the interface coalescing, and constructs a Java interface coalescing obfuscator. Experimental results show that the designed obfuscator obtains better effect of code obfuscation and hides efficiently the program class diagram, and it has not the extra execution time and lots of redundant code.
