A New Restrictive Partially Blind Signature with Designated Verifier

A restrictive partially blind signatures have two characteristics. Firstly, signatures allow a receiver to get a blind signature on a message unknown to the signer but choice of the message is restricted and must conform to certain rules. Secondly, signatures allow a signer to explicitly include necessary information in the resulting signatures under some agreement with the receiver. A designated verifier signature can provide authentication of a message with providing an undeniable property. In this paper we first propose a new designated verifier restrictive partially blind signature. This signature incorporates the advantages of restrictive partially blind signature and designated verifier signature.
