摘要

本文提出了一种称作隐式ＥｌＧａｍａｌ型签名方案的新方案。在这种签名方案中，真实签名被隐蔽起来，签名者仅将隐式签名送签名收方。我们在广义ＥｌＧａｍａｌ型签名方案上构造了许多隐式签名方案。分析表明，隐式ＥｌＧａｍａｌ型签名方案不但较源ＥｌＧａｍａｌ型签名方案更安全，而且可以被用来封闭阈下信道以及同时签发两个不同的消息。

Abstract

This paper presents a new kind of scheme called concealed ElGamal type signature schemes.In these schemes

ordinary true signatures are concealed

the signer only send the concealed signatures to the receiver.Many concealed signatures are proposed based on generalized ElGamal type signature schemes.Analysis shows that the concealed ElGamal type signature schemes not only are more secure than ordinary ElGamal type signature schemes

but also can used to seal subliminal channel and sign two different messages at once.
