  • Abstract
    At PKC´08, Libert and Vergnaud presented the first construction of unidirectional proxy re-encryption scheme with chosen-ciphertext security in the standard model. The limitation of their scheme is using one time signature. In this paper, an improved unidirectional chosen-ciphertext secure proxy re-encryption scheme is proposed. Our construction is more efficient than Libert and Vergnaud´s scheme by avoiding one time signature.
