摘要

Recently,many quantum digital signature (QDS) schemes have been proposed to authenticate the integration of a message.However,these quantum signature schemes just consider the situation for bit messages,and the signing-verifying of one-bit modality.So,their signature efficiency is very low.In this paper,we propose a scheme based on an application of Fibonacci-,Lucas-and Fibonacci-Lucas matrix coding to quantum digital signatures based on a recently proposed quantum key distribution (QKD) system.Our scheme can sign a large number of digital messages every time.Moreover,these special matrices provide a method to verify the integration of information received by the participants,to authenticate the identity of the participants,and to improve the efficiency for signing-verifying.Therefore,our signature scheme is more practical than the existing schemes.
