摘要:

由于量子力学中的海森堡测不准原理和不可克隆原理,以量子态为载体的量子货币在防伪造、防双花以及抗量子计算方面都具有一定的优势。文章根据银行、支票签发者及接收者的信息进行支票生成、签发及验证的场景,设计了使用Bell态的量子支票协议,并对其正确性、可验证性、不可伪造性、不可否认性、防篡改性等方面进行了分析。与现有量子支票方案相比较,文章方案降低了所需量子态的纠缠要求,提高了可行性。

关键词: 量子支票, 量子货币, Bell态

Abstract:

Based on Heisenberg’s uncertainty principle and non-cloning principle in quantum mechanics, quantum money with quantum states as the carrier has certain advantages in anti-counterfeiting, anti-double-spending and anti-quantum computing. In this paper, according to the scenarios of bank, cheque issuer and receiver for cheque generation, issuance and verification, a quantum cheque protocol using Bell state is proposed, and its correctness, verifiability, unforgeability, non-repudiation and tamper-proof are analyzed. Compared with the existing quantum cheque schemes, this protocol reduces the requirement of quantum entanglement and improves the feasibility of implementation.

Key words: quantum cheque, quantum money, Bell state
