Abstract
In many content distribution systems it is important to both restrict access of content to authorized users and to protect the identities of these users. We show that current systems for encrypting content to a set of users are subject to attacks on user privacy. We propose a new mechanism, private broadcast encryption, to protect the privacy of users of encrypted file systems and content delivery systems. We construct a private broadcast scheme, with a strong privacy guarantee against an active attacker, while achieving ciphertext length, encryption time, and decryption time comparable with the non-private schemes currently used in encrypted file systems.
