A Secure Proxy Blind Signature Scheme Based on DLP

摘要：

In this paper, we aim to improve the recently proposed Yang et al.’s proxy blind signature scheme in order to withstand the security flaw in their scheme. The security of the improved scheme is enhanced in the signing phase and based on difficulty of solving the discrete logarithm problem (DLP). The analysis shows that the proposed scheme resolves security problem in Yang et al.’s scheme and also meets the aspects of security features needed by a proxy blind signature.
