摘　　要：基于身份的聚合签名方案的提出为验证人员对多个基于身份的签名(这些签名是多个用户分别用自己的身份对多个不同的消息进行签名所得)进行一次性验证提供了方便。基于椭圆曲线中的m-挠群给出一种基于身份的聚合签名方案,并证明该方案在随机预言模型下是安全的。该方案具有两大优点:一是聚合签名减少了签名验证的工作量,提高了工作效率;二是以签名人员的身份作为验证公钥,解决了公钥管理问题。The ID-based aggregate signature scheme facilitates the verifiers carry out one-off verifications on different ID-based signatures （ these signatures are the results of more than one user signing different messages each on their own behalf）. We propose an ID-based aggre- gate signature scheme based on m-torsion group of elliptic curve in this paper, and prove that it is secure in random oracle model. This scheme has two advantages ,one is the reduction of the workload in verifying signatures with aggregate signature which lead to the operation efficiency enhanced, and the other is that it resolves the public keys management problem by using signers＇ identities as the verification keys.
