摘要:

研究无证书广义指定验证者聚合签名的安全模型,基于双线性映射提出无证书广义指定验证者聚合签名方案。在随机预言模型和计算 Diffie-Hellman 困难问题假设下,证明方案不仅可以抵抗无证书广义指定验证者聚合签名的3类伪造攻击,而且满足指定验证性和不可传递性。方案的聚合签名长度和单用户签名长度相当,签名公共验证和指定验证需要的双线性对数固定。

Abstract:

The security model of the certificateless aggregate signature scheme with universal designated verifier was studied,and then a certificateless aggregate signature scheme with universal designated verifier using bilinear pairings was proposed.In the random oracle mode,based on the hardness of the computational Diffie-Hellman problem,the new scheme was proved to be secure against three attacks of certificateless aggregate signature scheme with universal designated verifier.Meanwhile,the scheme satisfies properties of strong designated verify and non-transferability.Furthermore,the length of final aggregate signature is equivalent as the length of signal user’s signature,it is more efficient than others because the pairing computation is fixed among public verifies and designed verifies.

Key words: aggregate signature, certificateless signature, universal designated verifier, computational Diffie-Hellman problem
