摘　　要：提出了基于身份及RSA的简短代理环签名方法,该方法包括6个算法:Generation,Extract,ProxyDelegation,VerifyDelegation,Sign和Verify.该方法使密钥和签名长度缩短,提高了计算效率;在效率和实用性方面优于现有方法,不受代理密钥暴露攻击的影响,证明其具有强不可伪造性,具有安全性.A short proxy ring signature scheme based on identity and RSA was proposed. The scheme includes six algorithms： Generation, Extract, ProxyDelegation, VerifyDeIegation, Sign and Verify. The proposed scheme reduces the length of key and signature, and improves the computing efficiency; it is superior to the existing schme in terms of efficiency and practicability, and is not affected by the proxy key exposure attack. It is proved to have strong unforgeabilityand security.
