    摘要:

    提出了一种证实数字签名方案.该方案采用了Camenisch-Michels给出的证实数字签名的模型,首次将数字签名专用算法DSA和著名的RSA公钥加密方案用于证实数字签名方案中,并首次使用了否认零知识证明的新方法.该方案可应用于电子合同的公平签署.

    Abstract:

    A confirmer signature scheme is proposed. This scheme is designed according to Camennisch-Michels?confirmer signature model. It is the first time that the widely used digital signature algorithm DSA and famous public key cryptosystem RSA are being used in confirmer signature scheme, and a new method of zero-knowledge proof for denying protocol is used. This scheme can be used in fair electronic contract signing schemes.
