关于量子信息量子签名的存在性

On the existence of quantum signature for quantum messages

Qin Li, Wai Hong Chan, Chunhui Wu, Zhonghua Wen

摘要:

量子签名(QS)用于认证发起者的身份,保证数据的完整性,提供无条件安全的不可否认服务。根据是否有可信的第三方仲裁者参与,QS可分为仲裁QS和真QS。本文研究了这两类量子系统的存在性问题,主要贡献有两点:1)给出了一个基本框架,分析了在量子信息签名中仲裁量子系统的可能性; 2)解决了真量子系统的不可能性与现有真量子系统方案之间的矛盾。

英文摘要:

Quantum signature (QS) is used to authenticate the identity of the originator, ensure data integrity and provide non-repudiation service with unconditional security. Depending on whether a trusted third party named arbitrator is involved or not, QS is classified as arbitrated QS and true QS. This paper studies existence problem about the two kinds of QS and contributes to two points: 1) a basic framework is provided to analyze the possibility of arbitrated QS on signing quantum messages; 2) disagreement between the impossibility of true QS and an existing true QS scheme is solved.
