A P2P Application Demonstration System for Resilient Overlay Networks with Intelligent Nodes Supporting DRM

The widespread application of P2P file sharing brings about some critical problems, such as security, piracy and intellectual property. In order to protect the intellectual property rights of radio film and television resources, in this paper, under the environment of China next generation Internet (CNGI), a PCADRM (P2P-based content access digital rights management) system is constructed, which is based on the resilient overlay networks with intelligent nodes. Furthermore, a media player supporting DRM is designed and implemented, which provides users to purchase IPv6 network-based rights certificate and play media resource files in a secure way. Additionally, an application demonstration system, a typical application of the PCADRM over CERNET2 and other CNGI networks, is given.
