Abstract

Abstract: This paper gives a new construction of certificateless proxy signature scheme using bilinear maps.The security of the scheme is based on the infeasibility of the computational Diffie-Hellman problem and is formally proven in the strongest security model of certificateless proxy signature schemes.The new scheme satisfies the security requirements such as verifiability，strong undeniability，strong identifiability and prevention of misuse for a proxy signature scheme.Due to its security，high efficiency and free of certificate management，it may have practical applications in electronic commerce and electronic auction，etc.

Key words: certificateless cryptography, proxy signature, bilinear map, computational Diffie-Hellman problem

摘要： 利用双线性映射设计一个新的无证书代理签名方案。在最强的安全模型下，该方案给出了正式的安全证明，它的安全性基于计算Diffie-Hellman问题的困难性。并且该方案满足诸如可验证性、强不可否认性、强可识别性、防止签名滥用等安全性质。鉴于该方案安全、高效和无证书管理的优点，它可广泛应用于电子商务、电子拍卖等方面。
