“…Presently, many public-key-based PS schemes [6,[10][11][12][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] are proposed in the random oracle model or standard model, which are based on various mathematical problem assumptions, such as computational Diffie-Hellman (CDH) problem [9,10,28,34,36,42], factoring problem [40], discrete logarithm problem [27,29,30,35] and extended kplus problem [39]. Also, based on identity-based cryptography, many variants of public-key-based PS are proposed [18][19][20][21][22][23][24][46][47][48][49].…”

Presently, many identity-based proxy signature (IBPS) schemes have been proposed, but most of them are constructed in the random oracle model. Also, the proposed security model for IBPS is not enough complete according to Boldyreva's work. Cao and Cao proposed an IBPS scheme in the standard model. However, their scheme is not secure because of not resisting the attack of delegator and requires more computation cost. In this paper, we present a framework for IBPS and show a detailed security model for IBPS. Under our framework, we present an efficient IBPS scheme in the standard model. Compared with other IBPS schemes, the proposed scheme has more complete security and is more efficient.

Proxy signature is a specific digital signature, which allows an original signer to delegate her signing capability to proxy signer and then, the later can perform message signing on behalf of the former. Authentication is a desired property in cryptographic protocols. The proxy signature provides this property. In this article, we cover the research progress made on proxy signature and investigate its relationships with other existing signature schemes having continuous progress until now. We also provide real‐world scenarios, to understand better the situations, where these schemes are applicable for security purposes. We analyze the security properties of existing schemes and make a comparison among them on the basis of different number theoretic problems. Some open problems are also discussed, to the best of our knowledge. In addition, we provide some future directions, which can be used as a hint to work further in the area of proxy signature. We hope that this article will provide a ready reference to work in the related area. Copyright © 2012 John Wiley & Sons, Ltd.
