目前，透明加密技术在Windows平台下已经得到了广泛的应用，但在移动平台下的应用还有待探索。针对目前日益突出的手机数据安全问题，在对比分析了钩子透明加密和驱动透明加密这两种主要透明加密技术的基础上，设计了一种基于Android平台的文件透明加密系统。为了与传统手机加密系统区别开来，系统的身份验证环节被转移到Android手机自带的屏幕解锁环节上，有效提高了加密效率和用户体验。文中描述了该系统的总体设计方案和各个模块的设计方法，并给出了内核模块所使用的一些关键技术和重要的实现方法。测试数据表明，该系统能有效对手机应用程序和文件进行透明加密，同时又有较好的加密效率和用户体验。

Transparent encryption technology has been widely used in Windows now. However,it still needs some time in Android. Ai-ming at the increasingly prominent security problem of cellphone data,design a file transparent encryption system based on Android,on the basis of an analysis and comparison of Hook transparent encryption technology and Driver transparent encryption technology. In order to be different from traditional encryption systems used in cellphone,the authentication is shift to the course of Android's screen-unloc-king,thus encryption efficiency and user experience are improved. The whole system design scheme as well as design methods of each model is described,and give the key technologies and important realization methods for internal core module. Test results show that this system can realize the transparent encryption of a cellphone's applications and files effectively with good encryption efficiency and user experience.
