Recently, many quantum digital signature (QDS) schemes have been proposed to authenticate the integration ofa message. However, these quantum signature schemes just considerthe situation for bit messages, and the signing-verifying of one-bitmodality. 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 signaturesbased 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 theintegration of information received by the participants, toauthenticate the identity of the participants, and to improve theefficiency for signing-verifying. Therefore, our signature scheme ismore practical than the existing schemes.
