The Multi-level Security for the Android OS

摘要: Recently, the Android smartphone has become a frequent target of attackers. The provides personalized services such as finance and healthcare application, so attackers may invade user’s privacy by compromising smartphone. platform permission based security model, but there are several vulnerabilities. First, when components communicate through message passing mechanism, can eavesdrop or intercept message. It lead to leakage sensitive information. Second, non-privileged caller access more privileged callee exploiting vulnerable interfaces. In this paper, we propose multi-level framework protect against attacks described above. Our assigns level all applications, it regulates communication between at runtime.
