与 P2P 技术的成熟，有更多；对数字权利的保护的更多的挑战。为传统的客户机 / 服务器模型的 DRM 不能满足 P2P 网络的数字正确保护的要求。用 P2P 的实际申请联网技术；新辈份的 DRM 技术，文章基于信任为 P2P 系统建议一个 DRM 模型度。建议模型分享秘密钥匙到可信任的同伴；负担得起必要安全基于 P2P 技术为数字内容交货保证。数学分析；模拟证明与当前的 DRM 模型相比，建议模型是更柔韧的宽容播送；安全。

英文摘要：

With the maturation of P2P technology, there are more and more challenges to the protection of digital rights. DRM for traditional Client/Server model can not satisfy the requirement of digital right protection of P2P network. With practical application of P2P network technology and new generational DRM technology, the article proposes a DRM model for P2P system based on trust degree. The proposed model shares the secret key to the trusty peers and affords necessary security ensure for digital content delivery based on P2P technology. Mathematic analyses and simulations show that, compared to the current DRM model, the proposed model is more robust toleration of transmit and security.
