| English Abstract | 针对适用于移动通信的代理保护代理签名方案和代理聚合签名方案存在的不满足强不可伪造性和强不可否认性的安全缺陷,提出了2个改进的代理签名方案,当代理私钥生成时,添加一个随机数,使得原始签名者不能够假冒代理签名者进行伪造攻击.安全性分析与证明表明:改进方案满足代理签名的基本安全性质,在随机预言机下是可证明安全的;同时,在适应性选择消息攻击下,其代理生成协议是安全的. |

| Abstract | Proxy-protected proxy signature and proxy aggregate signature schemes were improved to advance the performances of these two proxy signature protocols. A random number was added to generate the proxy secret key, so that the new improved schemes could protect the proxy signers to resist the attacks from the original signer. Furthermore, the security analysis shows that the proposed protocols are provably secure under the random oracle. And the proxy generation scheme of the protocols are IND-CPA (indistinguishable against chosen plaintext attack) secure. |
