基于特征字符串动态引用频率的库引用识别

Identify library reference based on dynamic frequency of character strings

提出基于特征字符串动态引用频率的程序胎记,分析了其应对编译优化、压缩混淆的能力,设计了其提取算法;通过对库引用问题的分析,提出了其相似性函数,通过实例验证了上述动态程序胎记和相似性函数在分析库引用问题上的有效性。

This paper proposes a dynamic software birthmark, analyzes its ability against of compiling optimization and compress confusion, designs its extraction algorithms. It analyzes the character of lib reference and proposes the similar function of lib reference. It verifies the validity of the dynamic software birthmark and similar function through instance.
