이 편지는 다수의 공모 도청자가 PU(기본 사용자)를 도청하는 CR(인지 무선) 네트워크의 물리적 계층 보안을 연구합니다. PU를 보호하기 위한 PU 비밀 중단 제약 조건 하에서 보조 사용자(SU)는 전송이 허용되는 것으로 가정됩니다. SU 에르고딕 전송 속도를 최대화하기 위한 공동 SU 스케줄링 및 전력 제어 문제는 완벽한 채널 상태 정보(CSI) 시나리오와 불완전한 채널 상태 정보(CSI) 시나리오 모두에 대해 조사되었습니다. 공모적 도청자는 비공동적 도청자에 비해 PU 성능을 저하시키지만 실제로는 도청자 수가 많을수록 SU 성능이 향상되는 것으로 나타났다. 또한 불완전한 CSI를 사용하는 우리가 제안한 방식은 PU 성능이 불완전한 CSI에 의해 영향을 받지 않음을 보장할 수 있음을 보여줍니다.

Abstract: This letter studies physical-layer security in a cognitive radio (CR) network, where a primary user (PU) is eavesdropped by multiple collusive eavesdroppers. Under the PU secrecy outage constraint to protect the PU, the secondary users (SUs) are assumed to be allowed to transmit. The problem of joint SU scheduling and power control to maximize the SU ergodic transmission rate is investigated for both the scenarios of perfect and imperfect channel state information (CSI). It is shown that, although collusive eavesdroppers degrade the PU performance compared to non-collusive eavesdroppers, the SU performance is actually improved when the number of eavesdroppers is large. It is also shown that our proposed scheme with imperfect CSI can guarantee that the PU performance is unaffected by imperfect CSI.

AB - This letter studies physical-layer security in a cognitive radio (CR) network, where a primary user (PU) is eavesdropped by multiple collusive eavesdroppers. Under the PU secrecy outage constraint to protect the PU, the secondary users (SUs) are assumed to be allowed to transmit. The problem of joint SU scheduling and power control to maximize the SU ergodic transmission rate is investigated for both the scenarios of perfect and imperfect channel state information (CSI). It is shown that, although collusive eavesdroppers degrade the PU performance compared to non-collusive eavesdroppers, the SU performance is actually improved when the number of eavesdroppers is large. It is also shown that our proposed scheme with imperfect CSI can guarantee that the PU performance is unaffected by imperfect CSI.
