摘　　要：双限性对易于实现复杂密码协议,为了简化公钥密码体制证书管理的负担,采用双线性对技术实现了一种结构化重签名方案并给出该方案的仿真结果。方案以用户的身份信息,如电子邮箱地址,IP地址、电话号码等作为用户公钥,从而降低了建立和管理公钥基础设施的代价,避免了用户对公钥及其证书的存储和传递等问题,仿真结果显示其签名与验证签名时间开销是原方案3/4。Bilinear pairs can easily realize complex cryptography protocol. In order to simplify the burden of certificate management of public key cryptography, a novel identity-based structured multi-signature was proposed by using bilinear pairing technology. The scheme took the user＇s identity information as public key such as e-mail address, IP address, telephone number so that it erased the cost of forming and managing Public Key Infrastructure （PKI） and avoided the problem of user＇s storing, receiving and sending his public key and certificate. The simulation results of the proposed scheme show that the cost of signing and verifying in the scheme is only 3/4 of the original scheme.
