Abstract:
The content sharing based on device-to-device (D2D) communications is considered as a promising technology to face the challenge due to the explosive growth of wireless data traffic. To achieve the content sharing based on D2D communications, the problem of the security is a huge challenge. In this paper, we consider the secure content caching in content sharing scenarios based on D2D communications. The secure content caching is formulated as the maximum of the sum cache hit rate in the framework of physical layer security. Further, we model the secure content caching as an exact potential game. Subsequently, we design a secure content caching scheme based on no-regret procedure to converge to the correlated equilibrium of the pro-posed potential game. To verify the performance of the proposed secure content caching scheme, we discuss the computational complexity of the proposed secure content caching scheme. In addition, simulation results verify that the performance of our proposed secure content caching scheme is near-optimal.
