摘　　要：D2D通信技术在改善无线系统频谱效率和能量效能方面具有巨大潜能,因此在第五代移动通信网络中拥有大好前景。目前,针对D2D通信的研究主要集中在干扰避免、资源分配等方面,而对其安全性方面的考量较少。着眼D2D通信的物理层安全,考虑在满足D2D安全中断概率需求的条件下如何进行功率控制和信道接入来最大化网络容量的问题,从而在理论分析的基础上获得了功率控制和信道接入算法,并通过数值仿真验证了算法的有效性和可行性。D2D communications is a promising technology in 5G mobile communication network for its great potential in improving spectrum efficiency and energy efficiency of wireless systems. At present, much research of D2D communications is focused on interference avoidance and resource allocation, while less consideration on security. With focus on the physical layer security of D2D communications, and consideration on maximization problem of network capacity through power control and channel access of D2D communications in meeting the security outage probability of D2D communicationsk, the corresponding algorithm is derived through theory analysis, and meanwhile, its availability is verified via numerical simulation.
