A DRM system based on mobile agent for digital rights redistribution

We propose a digital rights management (DRM) system based on mobile agent to protect the copyrights of content providers. In the system, the content provider creates a time limited blackbox out of an original agent and dispatches it to the user end to enforce DRM functions. The blackbox is an agent that can resist the attacks from the malicious user in a certain time interval. Owing to digital rights redistribution support, the user whose rights belong to redistribution category can transfer his rights to other users. Moreover, by introducing public key infrastructure (PKI) and certificate authority (CA) role, the security of the session can be ensured. An analysis of system security and performance and a comparison with traditional DRM system is given. Biography: LI Ping(1974–), male, Ph. D. candidate, research direction: multimedia security.
