“…That is, Saint provides install-time permission granting policies as well as runtime inter-application communication policies for improved Android security. L4Android [16] runs multiple OS platforms on a single smartphone for isolation and security. AdDroid [17] and AdSplit [18] are approaches to separate the privileges between the ad library and its host app to remove the permission requests by the host app on behalf of its ad library.…”

Android is the world's most utilized smartphone OS which consequently, also makes it an attractive target for attackers. The most representative method of hacking used against Android apps is known as repackaging. This attack method requires extensive knowledge about reverse engineering in order to modify and insert malicious codes into the original app. However, there exists an easier way which circumvents the limiting obstacle of the reverse engineering. We have discovered a method of exploiting the Android code-signing process in order to mount a malware as an example. We also propose a countermeasure to prevent this attack. In addition, as a proof-of-concept, we tested a malicious code based on our attack technique on a sample app and improved the java libraries related to code-signing/verification reflecting our countermeasure.

Smartphone technology is going through revolutionary changes. As number of smartphones is exceeding the number of desktops, researchers are thinking of new ways to expand the capabilities of smartphones. Key problems that researchers are trying to solve include vendor lock-ins, isolation, security, and mobile cloud computing. Limited processing power, battery and storage are also an issue. Virtualization of mobile devices is believed to address most of these problems. This paper describes our work on virtualization of smartphones. Our work involves running virtual instances of smartphones on a single physical phone or cloud, as well as on-loading and off-loading application states to and from real and virtual smartphones. Research challenges we are facing include handling latency conditions, optimizing bandwidth usage, sharing resources, etc.
