A Dynamic Online Protection Framework for Android Applications

At present, Android is the most popular Operating System (OS) which is widespreadly installed on mobile phones, smart TVs and other wearable devices.Due to its overwhelming market share, Android attracts the attentions from many attackers. Reverse Engineering technology plays an important role inthe field of Android security, such as cracking applications, malware analysis, software protection, etc. In order to prevent others from obtaining the realcodes and tampering them, this paper designs and implements a online dynamic protection framework by deploying dynamic anti-debugging technologyfor Android application with comprehensive utilization of encryption, dynamic loading and shell technologies. Evaluated the performance on differentaspects, the proposed framework can work effectively for Android application protection. Comparing with the static protection scheme, the proposed onlinedynamic protection framework can prevent the android applications from cracking and malicious analysis to the utmost.
