DRM Security Framework: ID-Based Approach for Content Super-Distribution

摘要

DRM is a wide range of sophisticated technology for digital rights enforcement. We focus on the content protection by constructing a trusted environment under the cryptographic technology. We suggest to adopt ID based cryptosystem to DRM in which anyone can give or rend content to another client if he or she knows receiver's ID, without management of certificate. Further more, protected content can be exchanged among clients even by e-mail and receiver can use it without connecting to the server. Obviously, it provides efficient and convenient P2P business environment to the end-user for content super-distribution.
