P2P(Peer to Peer)는 오늘날 가장 주목 받는 파일 공유 시스템으로 현재 네트워크 트래픽의 50% 가량을 점유하고 있을 정도로 많은 콘텐츠의 유통경로가 되고 있다. 이처럼 P2P는 가장 큰 콘텐츠 유통 경로로 활용되기도 하지만 콘텐츠의 가장 큰 불법 유통 경로로 활용되기도 하며 최근에 들어 음악산업뿐만 아니라 영상산업 전반으로 불법 유통을 야기시키고 있으나 현재 이를 방지하면서 P2P의 장점을 최대한 살릴 수 있는 DRM(Digital Right Management)이 적용된 P2P모델 이 제시되지 못하고 있다.이에 본 논문에서는 기존 DRM기능들을 변형하여 기존에 P2P모델에 적합한 형태로 적용함으로써 기존의 P2P 모델구조를 변형시키지 않고 P2P의 높은 확장성(Scalability)과 분산 처리 성능을 지원할 수 있는 콘텐츠 보호를 위한 DRM이 적용된 P2P 모델을 제안한다.
