NEW ARBITRATED QUANTUM SIGNATURE WITH MESSAGE RECOVERY
Jianhua Zhang · International Journal of Quantum Information · 2011
Recently, Lee proposed two quantum signature schemes with message recovery. This paper shows insecurity in their schemes such that the scheme could be repudiated by the receiver Bob. Then, this paper proposes an arbitrated quantum signature scheme based on the correlation of Einstein–Podolsky–Rosen (EPR) pairs. Compared with Lee's scheme, the new scheme not only maintains the advantages of the original scheme but offers a higher efficiency in transmission and it can also avoid being disavowed by the receiver.
