Using inverse instruction stream to realize the file encryption;
采用“逆指令流方式”实现文件加密
The generation method of random instruction sequence and relevant reverse instruction sequence for constructing self-sealing code blocks were emphasized,including random original instruction sequence generation based on instruction encode table and reverse instruction sequence generation based on reverse engineering.
重点介绍了自封闭代码块的相关概念,阐述了自封闭代码块的自动生成技术,包括基于指令编码表的随机指令序列生成技术和基于指令逆向思想的逆指令序列生成技术,并给出了相关算法和实例分析。
