Abstract
We consider a problem of key leakage in peer-to-peer (P2P) content distribution. In content-distribution services, content is encrypted so that only legitimate users can access the content. Users (peers) cannot be fully trusted in a P2P network because malicious ones might leak their decryption keys. If the redistribution of decryption keys occurs, copyright holders may incur great losses caused by free riders who access content without purchasing it. Therefore, it is essential to solve this problem. In this paper, we propose a P2P content-distribution scheme resilient to the key leakage, and show its feasibility by conducting a large-scale experiment in a real network.
