| 摘 要： | 在一个代理多重签名方案中,一个被指定的代理签名人可以同时代表一群原始签名人生成一个有效的签名。这些年来,虽然已经提出了许多的代理多重签名方案及改进方案,但是这些已知方案的安全性都是基于启发式的分析或者是在随机预言机模型下安全的。到目前为止,还未有一个基于标准模型下安全的代理多重签名方案。基于Waters的签名方案,提出了一个在标准模型下可证安全的理多重签名方案。

| Abstract: | In general,in a proxy multi-signature scheme,a designated proxy signer can generate the signature on behalf of a group of original signers.Although many proxy multi-signature schemes have been proposed or improved in the last few years,the securities of all previous known proxy multi-signature schemes are based on the random oracle model or only heuristic analysis.Up to now,there is no provably secure proxy multi-signature scheme in the standard model.Based on the Waters’signature scheme,it proposes the proxy multi-signature scheme whose security can be proven in the standard model. |
