【摘要】 提出了一种拥有RSA数字签名的零知识证明方案。该方案给出了防止RSA数字签名任意传播的一种新方法——签名者不直接提供对信息M的签名,而是提供拥有对该信息的数字签名的一个零知识证明。该方案是可证实数字签名的改进,但比证实签名简单且不需要第三方的参与。本文中给的方案,可广泛应用于信息产品的版权保护中。1更多还原

【Abstract】 Zero-knowledge proof schemes of possessing a RSA digital signature are proposed. The schemes give a new method of preventing arbitrary propagation of digital signature. By which the prover does not need to give directly the signature of the message, but to give a zero-knowledge proof of possessing a digital signature. The schemes are the improvement of confirm signature, and is much simpler in practice and of significant feature that it does not need the third party to take part in the scheme. The schemes can be used in copyright protection.更多还原
