Mobile application reinforcement method based on control flow and data flow confusion

At present, mobile applications are developing rapidly, and the methods of attacking mobile applications by reverse engineering to obtain the core logic of the program are becoming more and more intense. In the face of malicious tampering, permission bypassing or obtaining core intellectual property rights through reverse engineering of mobile application, this paper proposes a mobile application reinforcement method based on control flow and data flow confusion, and factors affecting the accuracy and complexity of program analysis extracted for mobile applications, analyze its own characteristics and the relationship between them, detailed analysis of the implementation principle and code of the variable target compiler, in the syntax analysis and semantic analysis stage, the corresponding code obfuscation algorithm is implemented. Through obfuscation, the compiled program is strengthened at the three levels of grammar, control flow, and data flow. Experiments show that even if the source code of mobile application reinforced by this method is obtained through decompilation, the internal logic of the application cannot be known, and the next attack cannot be initiated.
