Cloud Security Solution of Mobile Applications based on Execution Offloading

Abstract

So far, security mechanisms for mobile devices have had difficulties to protect from malicious threats due to the limited resources of mobile devices. With the prevalence of cloud computing, one of promising solutions to overcome the difficulties is to exploit cloud environments, where a remote virtual machine performs the resource-consuming security analysis instead of a mobile device. However, existing cloud-based solutions are still insufficient because of the code coverage problem and security level degradation. Therefore, this thesis proposes a static and dynamic analysis based security solution called SORCloud. For dynamic analysis, it offloads a process of a suspicious application to a remote virtual machine for dynamic security analysis, by which SORCloud resolves two problems mentioned above. Through comprehensive experiments, we show how efficiently the proposed scheme works and detects malicious behavior
