摘要： 广义指定多个验证者签名允许签名持有者指定多个签名验证者，有序多重签名则可满足多个签名者以严格的次序进行签名的要求。根据上述特性，提出一种基于身份的广义指定多个验证者有序多重签名方案，采用类短签名的形式构造签名，并在随机预言模型下证明方案的安全性。分析结果表明，该方案具有较高的效率，可抵抗适应性选择消息和身份攻击。

Abstract: Universal designated multi-verifiers signature scheme allows a signature holder to designate the signature to a set of designated verifiers. Sequential multi-signature schemes can satisfy physical demanding which needs many signers to carry on the signature by the strict order. According to the above characteristics, this paper proposes an identity-based universal designated multi-verifiers sequential multi-signature scheme. The short signature is used to construct this new sequential multi-signature and the scheme’s security proof is provided under the random oracle model. Analysis results show that the scheme is extremely efficient and it can resist the adaptively select of message and identity attack.

Key words: identity-based, sequential multi-signature, universal designated multi-verifiers signature, Bilinear Diffie-Hellman(BDH) problem
