Estimate risks rate for Android applications using Android Permissions

In recent years, Android becomes the first target for hackers and malware developers, due to his inefficient permission model. In this article, we introduce our tool called PerUpSecure to manage permissions requested by Android applications, calculate the risk rates and display the results to the user, in order to help him to make a better decision. Thanks to our PerUpSecure, user will be able to install only the trusted application. As far as we know, the other existing tools focus only on measuring app risk after being installed, and not before as our tool does. Therefore, to evaluate our tool, we selected two different applications sets. The results show that our tool can produce the most trustworthy risk rate to prevent and detect potential malicious activities performed by malware.

Deep Reinforcement Learning for Task Offloading and Power Allocation in UAV-assisted MEC System

Mobile edge computing (MEC) can provide computing services for mobile users (MUs) by offloading computing tasks to edge clouds through wireless access networks. Unmanned aerial vehicles (UAVs) are deployed as supplementary edge clouds to provide effective MEC services for MUs with poor wireless communication condition. In this paper, a joint task offloading and power allocation (TOPA) optimization problem is investigated in UAV-assisted MEC system. Since the joint TOPA problem has a strong non-convex characteristic, a method based on deep reinforcement learning is proposed. Specifically, the joint TOPA problem is modeled as Markov decision process. Then, considering the large state space and continuous action space, a twin delayed deep deterministic policy gradient algorithm is proposed. Simulation results show that the proposed scheme has lower smoothing training cost than other optimization methods.
