Eadroid: Providing environment adaptive security for android system

Abstract

With the rapid popularization of Android system around the world, of the increase in Android malwares post serious threats to the security of users’ Android device and the privacy stored in it. At the same time, many trusted third party institutions (such as military, government institutions) need to customize the security policy of their Android devices according to their regulations, but most of them do not have this capability. This paper proposed an environment adaptive security mechanism for Android platform called EAdroid, which providing a simple way for trusted third party institutions to customize the security policy of their Android devices. EAdroid reforms the framework layer of Android system and synthetically applies Smack security module of Linux. At the same time, the security rules of framework layer and kernel layer in EAdroid can adapt to the current environment context. Series of tests show that EAdroid can efficiently protect the security of user’s devices and privacy with negligible overhead of performance.
