  Blind signature schemes enable a useful protocol that guarantee the anonymity
of the participants while Signcryption offers authentication of message and
confidentiality of messages at the same time and more efficiently. In this
paper, we present a blind signcryption scheme that combines the functionality
of blind signature and signcryption. This blind Signcryption is useful for
applications that are based on anonymity untracebility and unlinkability.
