Semantically rich application-centric security in Android

摘要: Smartphones are now ubiquitous. However, the security requirements of these relatively new systems and applications they support still being understood. As a result, infrastructure available in current smartphone operating is largely underdeveloped. In this paper, we consider augment existing Android system with framework to meet them. We present Secure Application INTeraction (Saint), modified that governs install-time permission assignment their run-time use as dictated by application provider policy. An in-depth description semantics policy presented. The architecture technical detail Saint given, areas for extension, optimization, improvement explored. demonstrate through concrete example study real-world provides necessary utility assert control decisions on platform.
