Title: Security Threats to Android System: Exploration,Understanding, and Defense




With the evolution of mobile computing technology, smartphone hasexperienced enormous growth in the consumer market, among which Android deviceshave taken the lion's share. Different from the traditional feature phone,smartphone is playing the role of personal assistant and data container inpeople's daily life. Therefore, it is inevitable that considerable private datais stored on the smartphone and becomes the target of attackers. Lots ofprevious research on mobile security concentrates on the program analysistechniques for malware detection and lack a deep investigation into the Androidsecurity architecture. In this talk, I will introduce my research efforts onthe new security threats to the Android's defense system itself, especially theSandbox mechanism. In particular, I will discuss (1) conducting side-channelattacks to bypass the Sandbox mechanism, (2) analyzing architecture flaws lyingin the Sandbox mechanism, and (3) designing new approaches to evade runtimesecurity check.
