摘要

Predicate encryption has an advantage over traditional public key or identity-based encryption, since predicate encryption systems pro vide more flexible control over access to encrypted data. We focus on delegation capabilities in predicate systems. More specifically, we inves tigate delegatable encryption systems supporting disjunctive predicate evaluations. We present formal security definitions of delegatable pred icate encryption and provide the first delegatable predicate encryption scheme which supports disjunctive predicate evaluations in the public key setting. We analyze the security of the proposed system and give a security proof.
