| 摘 要： | 针对D2D蜂窝系统通信安全性受资源限制的问题，考虑到蜂窝链路和D2D链路的同频干扰能够为两者带来安全增益，基于此，提出一种基于安全中断概率的D2D用户接入策略。首先理论分析了蜂窝用户和D2D用户的安全中断概率，并给出了基于安全中断概率最小化的D2D用户功率优化算法。在上述分析的基础上，选择安全中断概率最小的D2D用户接入复用蜂窝用户的无线资源，同时提高D2D通信链路和蜂窝上行链路的安全性。最后，仿真结果证明了所提算法的有效性。

| Abstract: | A secure access strategy for D2D (device-to-device) communications underlaying cellular networks based on the secrecy outage probability was proposed. Firstly, the secrecy outage probability in the worst case was derived and a transmission power optimization scheme for D2D pairs was given. An access control strategy was further presented to allow the D2D pair with the minimum secrecy outage probability to reuse the cellular resource, which improved the secure communications for D2D links and cellular uplinks. Finally, simulation results showed that the proposed scheme was effective. |
