Extending Android Security Enforcement with a Security Distance Model

Compared to the traditional operating system platforms, smart phone platforms have different infrastructures and security requirements. Therefore new corresponding security strategies are also required. In this paper firstly we analyze the Android applications' threats and existing security mechanisms' weakness. Then we present an extending of Android Security Enforcement with a Security Distance model, ASESD, to mitigate malware. The new scheme can be implemented in an Android phone and make applications more safe. Our theoratical anlyses and practical evaluations show ASESD more accurate and highly scalabe.
