摘　　要：为了保护原始签名人的隐私,提出了一种消息保密的代理签名方案。在代理授权过程中,原始签名人通过盲签名的方法把消息和其他代理授权参数一起传递给代理签名人,该方案能够保证除了指定的消息接收人外,其他人无法了解消息内容;在一些特殊的应用中,原始签名人希望在代理签名中隐藏代理签名人的身份,消息接收者无法从代理签名中识别代理人身份,在出现争议时,可以揭示代理人身份。提出的方案能够满足上述两种需求。A proxy signature scheme was proposed to protect original signer＇s privacy, In delegation authorization, the original signer encrypts the message and other delegating parameters to the proxy signer. The scheme ensures that the proxy singer and others except the valid receiver can not get any information from the message. In special application, the original signer wants to conceal the identity of the corresponding proxy signer in the proxy signature. The receiver can not recognize the identity of the proxy signer form the proxy signature. In the case of a later dispute, the original signer can reveal the real identity of the proxy signer with the help of the original signer from the proxy signature. In the paper, a new proxy signature scheme should satisfy this requirement,
