In a proxy blind signature scheme, the proxy signer is allowed to generate a blind signature on behalf of the original signer. The proxy blind signature scheme is useful in several applications such as e-voting, e-payment and mobile agent environments. This paper analyzed the security shortcoming of a proxy blind signature scheme which is proposed by Tan et al. Comparing with the weakness of the previous schemes, a new proxy blind signature scheme based Discrete Logarithm Problem (DLP) is presented to overcome the insecurity. It is proved that this scheme is more secure and efficient than the previous schemes. As an instance, the applying of the schemes in electronic voting is describing.
