本文提出了一种快速的适用于计算机网络通信的数字签名方法——随机校验签名,简称RV(Random Verification)签名。即随机任取少量的经非线性变换后的明文字符作为对消息签名的校验信息。并且详细论证了该签名方法的安全性。最给出了一种随机校验签名的实例。 This paper presents a fast digital signature method suitable for computer network communication - random verification signature, referred to as RV (Random Verification) signature. That is, a small amount of non-linear transformed plaintext characters are arbitrarily chosen as the verification information for signing the message. And the security of the signature method is demonstrated in detail. Mostly given an example of random verification signature.
