After a user, B, gets all of the encrypted pieces, B obtains a set of the decryption keys, K B , and the decryption key in the scheme of [14] from the KM server.

“…Technically, audio/video fingerprinting (e.g., [15]) and digital watermarking (e.g., [7]) can be used to detect unauthorized content and then identify who redistributed the content. For example, Gao et al [14] proposed an asymmetric fingerprint scheme which can be implemented to trace the malicious user by identifying his unique ID (as a fingerprint) from the content, then for example, a revocation process can be executed later. The existence of these measures deters users from the redistribution of content.…”

“…As long as the legal status of the redistribution of decryption keys is unclear, the copyright holder might not be able to claim damages against the piracy. Hence, we cannot take the technical measure in which any free rider can use leaked decryption keys, even though we can identify a user who leaked decryption keys using e.g., a fingerprint scheme such as [14].…”

“…Gao et al [14] applied an asymmetric fingerprinting scheme [16] to content protection in the P2P network. In their scheme, each user gets a slightly different fingerprinted content as follows: A distributor (a content server in our scheme) encrypts the content in such a way that each user decrypts the same encrypted content with a different key.…”

SUMMARY Peer-to-peer (P2P) networks have attracted increasing attention in the distribution of large-volume and frequently accessed content. In this paper, we mainly consider the problem of key leakage in secure P2P content distribution. In secure content distribution, content is encrypted so that only legitimate users can access the content. Usually, 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. To decrease the damage caused by the key leakage, the individualization of encrypted content is necessary. The individualization means that a different (set of) decryption key(s) is required for each user to access content. In this paper, we propose a P2P content distribution scheme resilient to the key leakage that achieves the individualization of encrypted content. We show the feasibility of our scheme by conducting a large-scale P2P experiment in a real network.
