| 摘 要： | 控制流速惑是代码迷惑的一个重要方面．程序控制流分为过程内控制流及过程间控制流．本文提出了一种基于switch_case语句的控制流迷惑技术；首先给出一种基于switch语句的程序变换方法，使得过程内的控制流关系变得复杂，同时利用switch语句对整个程序中的函数进行重新定义，从而迷惑程序中的函数调用关系，以达到迷惑过程间控制流信息的目的．最后表文定性地分析了这种代码迷惑技术的性能．

| Abstract: | Control Flow Obfuscation is one important aspect of code obfuscation.Program's control flow can be departed into two parts: Intra-procedural Control flow and inter-procedural control flow.This article gives out an algorithm of code obfuscation based on switch-case clause.Firstly it gives out a kind of program transformation based on switch clause to make the relation of control flow in a procedure more complex,and at the same time it uses the switch clause to redefine the functions of the whole program so as to obfuscate the function call relations,and the inter-procedural control flow information.Lastly the article implements part of the algorithm and analyze its efficiency |
