摘　　要：针对目前无证书多重签名方案在计算效率、通信成本和安全性等方面存在的问题,提出一种基于双线性对的无证书多重签名方案,并模拟3种不同类型的攻击者,分析新签名算法的不可伪造性.该方法基于无证书短签名的思想,构造签名长度较短的并行多重签名方案.仿真实验表明,与目前已有的方案相比,新方案降低了签名的通信成本和计算量,因此更适合于资源受限的网络环境.Aiming at the problems of computation efficiency,communication cost and security in the current certificateless multisignature scheme,we proposed a certificateless multisignature scheme based on bilinear pairings,simulated three different types of attackers,and analyzed the non forgery of the new signature algorithm.The method was based on the idea of certificateless short signature,and constructed a parallel multisignature scheme with short signature length.Simulation results show that,compared with the existing schemes,the new scheme reduces the communication cost and the amount of computation of the signature,so it is more suitable for resource constrained network environment.
