Anception: Application Virtualization For Android

摘要

The problem of malware has become significant on Android devices. Libraryoperating systems and application virtualization are both possible solutionsfor confining malware. Unfortunately, such solutions do not exist for Android.Designing mechanisms for application virtualization is a significant chal-lenge for several reasons: (1) graphics performance is important due topopularity of games and (2) applications with the same UID can share state.This paper presents Anception, the first flexible application virtualizationframework for Android. It is imple- mented as a modification to the Androidkernel and supports application virtualization that addresses the aboverequirements. Anception is able to confine many types of malware whilesupporting unmodified Android applications. Our Anception- based systemexhibits up to 3.9% overhead on various 2D/3D benchmarks, and 1.8% overhead onthe SunSpider benchmark.
