摘要
将无证书签名和多重签名两个概念相结合,提出无证书多重签名的概念及安全模型,并给出一个基于双线性对的无证书广播多重签名方案,其安全性是基于CDH困难假设.
By concatenating the notions of certificateless signature and multisignature, A new notion and security model of certificateless broadcasting multisignature are proposed, and a concrete certificateless multisignature scheme from bilinear pairings based on CDH assumption is constructed.
