A nonzero-sum game is established to capture the interaction among URs and detection strategies. Secrecy capacity is investigated as game payoff to indicate the untrusted behaviors of the relays. The maximum probabilities of the behaviors of relay and the optimal system detection strategy can be obtained by using the proposed algorithm. 关键词：physical layer security COOPERATIVE communication untrusted RELAY SECRECY capacity nonzero-sum GAME
