Paper detail

On the existence of quantum signature for quantum messages

Quantum signature (QS) is used to authenticate the identity of the originator, ensure data integrity and provide non-repudiation service with unconditional security. Depending on whether a trusted third party named arbitrator is involved or not, QS is classified as arbitrated QS and true QS. This paper studies existence problem about the two kinds of QS and contributes to two points: 1) a basic framework is provided to analyze the possibility of arbitrated QS on signing quantum messages; 2) disagreement between the impossibility of true QS and an existing true QS scheme is solved.
