文章在已有加密自检测防篡改技术的基础上，将软件代码和行为检测作为关键技术，引入基于分支转移的模糊化控制技术，保护客户端软件的完整性和安全性。文中给出了改进的防篡改系统以及系统主要模块，井对本系统做了安全性分析和测试实验。

英文摘要：

Upon with the encryption technology based on software self-checking tamper resistance and taken selfchecking and software behavior tracing as the key technology, the branch-based code obfuscation is introduced to protect the integrity and security of client software. This paper offers the modified tamper resistant system and its main modules, and analyzes the security of the scheme, and provides results of the experiment test .
