Currently existing Digital Rights Management systems employ appropriate methods for protecting contents. But these have high complexity and are too heavy to use in private broadcasting. This is not appropriate in IPTV system that will popularize the private broadcasting or UCC (User Created Contents). In this paper, we introduce a private broadcasting system based on P2P that prevents the illegal re-distribution of contents and protects the copyright of contents. Contrary to the general server/client framework, the proposed method has the P2P (Peer to Peer) framework that is broadly used for sharing the contents and the contents and their keys for playing them are distributed between each peer.
