Knowledge Signature-Based Forwardsecure Signature Scheme
Yuan Yan · Journal of Hubei University of Technology · 2010
With a in-depth study of the discrete logarithm signature of knowledge with a coefficient and forward-secure digital signature,a knowledge signature-based forward secure signature scheme is proposed against the signature schemes proposed by Wu Keli and Liu Yali.With public key in maintaining the same premise and the current key signature hidden in the algorithm,the security of the keys are guaranteed.Meanwhile,the identity of the signer hidden in the knowledge signature guarantees the security of the signer's identity.The forward security is based on discrete logarithm and the number of square residual problems,together with one-way hash function.The analysis shows that the proposed scheme is more secure.
