基于Android平台的代码保护技术研究

摘要

文章针对当前基于Android平台的代码保护技术的滞后性，介绍了Android平台的基本架构，结合当前Android平台下基于逆向分析技术的代码篡改和注入等破坏方式，采用静态分析和动态调试机制，研究了基于Android平台下的代码逆向分析技术及现有代码保护技术，提出了一种结合字节码填充、标识符混淆和动态代码加载技术的高性能代码保护方案。%This paper target to the lag of code protection technology for Android platform. It presents the basic architecture of the Android platform, along with the damage of code tampering and injection based on the reverse analysis technology on Android platform. It use static analysis and dynamic debugging methods to study code reverse analysis and code protection technology on Android platform. A high-performance code protection scheme was presented which combined with bytecode iflling, identiifer confusion and dynamic code-loading technology.
