Abstract (Summary of the Work)

Predicate encryption is a new paradigm generalizing, among other things, identitybased 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 f(I) = 1. Constructions of such schemes are currently known for relatively few classes of predicates.In 2008 Jonathon Katz et. al [14]. proposed Predicate Encryption scheme Supporting Disjunctions, Polynomial Equations, and Inner Products in [5]. In 2010 Angelo De Caro et. al [7]. proposed three secure Hidden Vector Encryption Scheme and demonstrated their security under certain hard Assumptions in [7].In this work we have pointed out some redundancy in the security proof of the Hierarchical Hidden Vector Encryption given in [7] and have given a new security proof for the scheme that removes the flaw. We have also done a brief survey on some important schemes of Attribute Based Encryption and Predicate Based Encryption.
