Reply to “Comment on ‘Arbitrated quantum-signature scheme’ ”
Guihua Zeng · Physical Review A · 2008
To reply to the Comment on our original paper entitled ``Arbitrated quantum-signature scheme'' [Phys. Rev. A 65, 042312 (2002)], we present more detailed presentations and proofs of the quantum-signature scheme in our paper. We feel our further investigation has shown that the original quantum-signature scheme is secure and operationally well defined. In addition, proofs illustrate that the quantum-signature scheme with unknown quantum states is also suitable in principle.
