英文摘要	In this paper, we investigate the physical layer security issue in Device-to-Device (D2D) communications underlaying cellular networks. In order to optimize the system secrecy rate of the cellular secure communication, we derive the optimal joint power control solutions of both the cellular communication links and D2D pairs in terms of the secrecy capacity. Furthermore, we propose a secrecy-based joint power and access control (JPAC) scheme with optimum D2D pair selection mechanism that can achieve an improved network secrecy performance with very low computational complexity. Simulation results validate the efficiency of the proposed secrecy-based JPAC scheme. ? 2016 IEEE.; EI
