Predicate Encryption Supporting Disjunctions, Polynomial Equations, and Inner Products

Predicate encryption is a new paradigm for public-key encryption generalizing, among other things, identity-based encryption. In a predicate encryption scheme, secret keys correspond to predicates and ciphertexts are associated with attributes; the secret key SKf corresponding to a predicate f can be used to decrypt a ciphertext associated with attribute I if and only if
