Signcryption [33] is a public key primitive that achieves the functionality of both an encryption scheme and a signature scheme simultaneously. It does this more efficiently than a composition of public key encryption and public key signature.We present a model of security for signcryption schemes that offer non-interactive non-repudiation. This is non-repudiation in which the judge settling a repudiation dispute does not have to get involved in an interactive zero-knowledge proof. Our model applies to many existing schemes in the literature Bao and Deng, [4] He and Wu, [22] Peterson and Michels, [28].We explain why the scheme proposed in Bao and Deng, [4] is insecure under any definition of privacy based on the idea of indistinguishable encryptions Goldwasser and Micali, [20]. We describe a modified scheme to overcome the problem. Proofs of security are given for the scheme in the random oracle model Bellare and Rogaway, [10].
