A Secure and Efficient of Some New Blind Signature, Proxy and Partial Blind Signature Scheme Based on Discrete Logarithm Problem

A blind signature scheme is a protocol for obtaining a signature from a signer such that the signer’ view of the protocol can’t be linked to the resulting messagesignature pair. A proxy blind signature scheme is a digital signature scheme which combines the properties of proxy signature and blind signature scheme. Partial blind signature scheme are an extension of blind signature scheme that allows a signer to explicitly include necessary information in the resulting signatures under some agreement with the receiver. In this paper we propose a secure and efficient of some new blind signature, proxy and partial blind signature scheme based on discrete logarithm problem
