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 se-cure communications for D2D links and cellular uplinks.Finally,simulation results showed that the proposed scheme was effective.

Key words: D2D communications, physical layer security, secrecy outage probability, power optimization, secure access
