A Trust-Scheme-Based DRM Model for P2P System

With the maturation of P2P technology, there are more and more challenges to the protection of digital rights. DRM for the traditional client/server model can not satisfy the requirement of digital right protection of P2P systems. Practical application of P2P network technology is combined with new generation DRM technology, and a DRM model for P2P system based on trust degree is given. The proposed model shares the secret key to the trusty peers and affords necessary security for digital content delivery based on P2P technology. Mathematic analyses and simulations show that compared with the current DRM model, the proposed model is more robust toleration of transmit and security.
