摘要/Abstract

摘要： 量子数字签名在保证消息的完整性和不可抵赖性的同时, 还具有基于量子力学的信息理论安全性。目前, 大多数关于量子数字签名的研究都基于多诱骗态协议。由于统计涨落等因素的存在, 多诱骗态会限制系统的性能。为了提高量子数字签名系统的性能, 提出一种单诱骗态量子数字签名协议, 并给出了该协议的安全性分析及性能仿真结果。通过数值模拟比较了单诱骗态协议和2 诱骗态协议的性能, 结果表明单诱骗态方法在大多数传输距离下虽然对系统的签名率仅有少许提升, 但是单诱骗态协议实现起来更加简单, 因此具有更高的实用性。

Abstract: Quantum digital signature (QDS) can guarantee the integrity and non-repudiation of messages with quantum mechanics-based information-theoretical security. Currently, most researches are concentrated on multi-decoy state QDS protocol. However, due to the existence of statistical fluctuations, the performance of multi-decoy state QDS systems could be deteriorated. In order to improve the performance of QDS, a 1-decoy state QDS protocol is proposed, and the corresponding security analysis and numerical simulation of its performance are also given. The signature rates with parameter optimization for 1-decoy state protocol and 2-decoy state protocol are compared through numerical simulation. It is shown that 1-decoy state protocol can improve the signature rate of the system a little under most transmission distance. In addition, 1-decoy state protocol is easier to be implemented, making it more practical and promising in possible digital signature scenarios.
