Abstract
물리계층 보안기법은 무선 채널의 통계적 특성에 의존하지 않는 인공노이즈 기법과 결합되어 MIMO 시스템, 멀티유저, 릴레이 시나리오 등 다양한 모델에서 연구되고 있다. 하지만 정교하게 수립되지 않는 무분별한 재밍 전략은 오히려 보안성능을 감소시키기 때문에 성능에 영향을 주는 요소들을 이론적으로 분석해야 한다. 따라서, 본 논문에서는 도청자가 존재하는 MIMO 채널에서 재밍파워와 노드배치의 관점에서 보안성능의 변화를 살펴보았다.

Physical layer security techniques have been studied in various models such as the MIMO system, multiple users, and relay scenarios combined with the artificial noise scheme that does not depend on the statistical characteristics of wireless channel. However, it is necessary to theoretically analyze the factors affecting the secrecy performance because the jamming strategies that are not elaborately established are rather detrimental to the performance. In this paper, we examined the change of security performances of the MIMO system regarding jamming power and node placements in the presence of eavesdroppers.
