Abstract
With the rapid popularity of P2P networks, the demand for digital rights management (DRM) in P2P mode is increasing quickly. The research on issuance of digital content licenses is the key issues in DRM. As for the centralized authorization systems, the security and the efficiency have certain defects. An improved distributed license authorization system is presented in this paper. And the nodes in the system are divided into six kinds of roles in accordance with theirs functions and a new non-interactive verifiable secret sharing protocol is introduced. Because of the adoptions of threshold secret sharing mechanism and the independent synthesis peers, the system security is improved in the transmission of digital content license and the burden of nodes is reduced in P2P networks. Each license authorization node gets the correct secret sharing by the non-interactive verifiable secret sharing protocol.
