“…The scheme supports almost all desirable features of a proxy signcryption scheme at a relatively low computational overhead compared to other schemes in literature (Gamage et al, 1999a;Duan et al, 2005). The proposed scheme employs warrants for the explicit specification of the signing rights of a designated proxy agent.…”

In this paper, a new proxy signcryption scheme is proposed suitable for use by resource constrained devices such as pagers and mobile phones. The proposed scheme is based on delegating the signing rights of the original signer to one of his proxies using warrants. The use of warrants enables explicit specification of the signing rights of the proxy agent. The proxy agent and the original signer are assumed to be registered within the same traditional public key infrastructure. To offer a higher level of security, the proxy key is derived from the personal key of the proxy signer to prevent the proxy signer from denying a signature it created and protects it from framing attacks mounted by the original signer against it. We also consider a variant of our main scheme that works over elliptic curves since they have proven recently the possibility of reducing the key sizes. He is an IEEE senior member.

“…Wang et al [24] pointed out that Li and Chen's scheme does not satisfy the strong unforgeability and forward secrecy. Wang and Cao [25] and Duan et al [26] proposed an identity-based proxy signcryption scheme, respectively. In 2005, Wang and Liu [27] proposed an identity-based threshold proxy signcryption scheme.…”

Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional signature-thenencryption approach. Signcryption has found many applications, such as electronic transaction protocol, mobile agent protocol, key management, and routing protocol. In this article, the state-of-the-art of identitybased signcryption (IBSC) is surveyed. We examine the security model of IBSC. We survey the existing IBSC schemes and compare their security properties and efficiency. IBSC with special properties and identitybased hybrid signcryption are investigated. Some possible future work is also pointed out. . His recent research interests include cryptography and network security. He has published more than 40 papers in international journals and conferences.

Proxy signcryption is a novel cryptographic primitive that combines the functionality of a proxy signature with that of a signcryption. However, the security of all the known proxy signcryption schemes were proven in the random oracle, which has received a lot of criticism that the proofs in the random oracle model are not sound with respect to the standard model. Hence, it is an interesting research problem on how to construct a provably secure proxy signcryption scheme in the standard model. In this paper, motivated by Waters' signature scheme, we propose a new construction of proxy signcryption scheme based on bilinear pairing without using random oracles. Then, we use the techniques from provable security to show that the proposed scheme is indistinguishability under adaptive chosen ciphertext attacks secure under the decisional bilinear Diffie-Hellman assumption and existentially unforgeable under the computational Diffie-Hellman assumptions. Compared with the existing schemes with formal security proof, we show that no pairing computation is required in our proxy signcrypt phase with pre-computations. To the best of our knowledge, our proposed scheme is the first provably secure proxy signcryption scheme in the standard model.
