Many Android vulnerabilities share a root cause of malicious
unauthorized applications executing without user's consent.
unauthorized applications executing without user's consent.
In this paper, we propose the use of a technique called process
authentication for Android applications to overcome
the shortcomings of current Android security practices. We
demonstrate the process authentication model for Android
by designing and implementing our runtime authentication
and detection system referred to as DroidBarrier. Our malware
analysis shows that DroidBarrier is capable of detecting
real Android malware at the time of creating independent
processes. A performance evaluation of DroidBarrier unveils
its low performance penalties.
