An Adaptive Trusted Request and Authorization Model for Mobile Peer-to-Peer Networks

Mobile P2P (MP2P) networks is open and complex, and hence secure communication is a challenging issue for MP2P applications. Peers in the dynamic networks sometimes can obtain each other´s trust and risk data, sometime or not. Nowadays, researchers can only study one for the two different scenarios, and thus the existing schemes are not universal and integrity. In this paper, we use the historical interaction information among the peers and game theory to design a Adaptive Trusted Request and Authorization Model (ATRAM) over MP2P networks. Whether the peers can obtain each other´s trust and risk data or not, ATRAM can guarantee the secure transaction among peers over the MP2P networks. The simulation results show that no matter how the MP2P networks environments vary, with the help of our model, the request peers always give first priority to connecting the secure resource peers and the resource peers always give first priority to authorizing the trusted request peers, which can greatly improve the efficiency of resource sharing over MP2P networks.
