Technique of Code Obfuscation Based on Class Splitting

摘要

The security of software is threatened by piracy,tampering and reverse engineering.Attackers attempt to get important algorithms and sensitive data of software by static analysis or reverse engineering.Software protection becomes an important problem.The algorithm of code obfuscation based on class splitting is proposed that uses of obfuscation technology.The definition of class splitting and realization on algorithm are described.At the same time,the performance on algorithm is analyzed.The obfuscation method enhances the degree of complication about program and static analysis becomes more difficult.The algorithm is applicable to object-oriented program with class structure.
