保护软件未经授权的访问是越来越艰巨的任务。 因此，在本文，着眼于源代码的迷惑手段保护和讨论控制流变换技术的适应称为C + +语言的控制流平展技术。 除适应的问题和解答办法之外，给出了算法的原型实现介绍。实验证明，程序的复杂性增加5倍。 -Protecting a software from unauthorized access is an ever demanding task. Thus, in this paper, we focus on the protection of source code by means of obfuscation and discuss the adaptation of a control flow transformation technique called control flow flattening to the C++ language. In addition to the problems of adaptation and the solutions proposed for them, a formal algorithm of the technique is given as well. A prototype implementation of the algorithm presents that the complexity of a program can show an increase as high as 5-fold due to the obfuscation.
