Abstract:

We propose a license management system for content separate delivery over P2P network. In trivial content delivery systems, a content file is delivered to a user bound license data within content-key simultaneously. However, a server needs to administer not only user license but also content files, and so server's load is heavy in these systems. In our proposed system, users can obtain a content file not only a content delivery server but also other and can be licensed for the content-key separated content delivery. Therefore, our proposed system is lightweight and scalable. Furthermore, for the purpose to show the feasibility, we have implemented a prototype system. As the result of the evaluation, we show our proposed system is secure and practical.
