Due to their various wireless interfaces, acontinuously increasing number of fishyApps, and due to their raising popularity,smartphones are becoming apromising target for attackers. Independently of the point of entrance, malwares are typically attached to an App to perform their malicious activities. However, malware can only do harm on asmartphone if it is executed. We thus propose amalware prevention architecture for smartphones that exploits App signatures, process authentication during

... r creation, and process verification during their execution and scheduling. The proposed security mechanism will allowasmartphone to run only those Apps which are classified as trusted (i.e., signed Apps) and which are not modified after their installation. The trust derivedfrom the App signatures and aMobile Trusted Module (MTM) is propagated through the processes until their execution via process authentication. The MTM serves as atrust anchor for our malware famishment in smartphones. This work presents our solution conceptually.W ew ill soon start with ap roof of concept implementation and aperformance study using asoftware based MTM emulator.
