Research on Dynamic Safe Loading Techniques in Android Application Protection System

摘要

Android is a widespread used embedded system. The number of Android applications has been rapidly growing. Because of Android open source policy and limited application security mechanism, Android applications are confronted with many serious security threats. By malicious reverse and illegal tampering, thousands of Android applications have been infected and millions of users have been exposed to dangers. In this paper, we proposed an improved Android applications protection system based on DEX block encryption and multi-file features checksum. Experiment results show that the proposed system is more reliable than the commonly-used Android application protection systems when facing with attack tools such as APK Tools and IDA pro.
