Abstract

Advances in quantum computer technology are threatening cryptographic systems based on mathematical complexity. As an alternative, quantum cryptography has been proposed and developed. Among the reported quantum cryptography systems, quantum key distribution (QKD) constitutes a symmetric key system that can securely distribute a secret key on a quantum channel. While there have been many studies on confidential communication using QKD, only a few of them address its application to the digital signature. In this paper, we propose a new digital signature method with public parameter and signature key through shared symmetric key from QKD. We also analyze the proposed plan from security.
