In this paper, we investigate the uplink secure communication for underlay device‐to‐device (D2D) communication sharing the uplink resources in cellular networks. We first develop a secrecy outage probability (SOP) minimization model while considering the secrecy requirements for both the cellular users and the D2D pairs. Then, we propose a transmission power optimization scheme for D2D pairs subject to the secrecy requirements of the cellular users, whereas the SOPs of all potential D2D pairs could achieve the minimum. To further support the security performance of this hybrid network, an access control strategy with optimal power strategy is considered in that the D2D pair with the minimum SOP is allowed to reuse the cellular resource. Finally, simulation results are provided to validate the effectiveness of the proposed scheme.
