Program semantic analysis model for code reuse detection
Program similarity analysis had a wide range of applications in areas such as code plagiarism and property pro-tection,but it generally suffered from problems such as excessive computational overhead,a code similarity analysis method based on fuzzy matching and statistical inference was proposed.For binary programs,first disassembly analysis was performed and then function boundary recognition operations was performed to extract the execution boundary in-formation of the function.On this basis,dynamic programming analysis methods were used to obtain similarity results between basic blocks at the granularity of the basic blocks,and neighborhood search was performed on the basis of the control flow graph to extend similarity analysis from the basic block level to the function level.Finally,the semantic similarity of binary files was obtained through statistical analysis of similarity functions.During this process,the pre trained model was optimized and analyzed,and the parameters were tuned to enable similarity analysis of cross platform code.The experimental results show that the proposed method has a significant improvement in analysis accuracy com-pared to traditional analysis tools,with an average increase of 7.1%in analysis accuracy compared to current mainstream analysis tools.
