摘要/Abstract

摘要： 根据反汇编器原理，分析现有的花指令加密算法存在的问题，提出了一种新的花指令加密算法——子程序花指令加密算法。详细论述了子程序花指令加密的工作流程和算法描述，分析了此算法的有效性和逻辑一致性。最后，通过算法的具体实现，对其有效性和逻辑一致性进行了验证。

Abstract: According to the disassembler principle，the problem of current junk code encryption strategies is analyzed.Based on these，a new junk code encryption algorithm is proposed，which is called the encryption algorithm of the sub-function junk code.The workflow and the algorithm description of the encryption for the sub-function junk code are particularly discussed.After this，the validity and the logic coherence of the algorithm are analyzed.Lastly，the validity and the logic coherence of the algorithm are confirmed by the concrete implementation.
