摘　　要：仅利用EPR粒子对的纠缠特性和量子密钥分发(QKD)技术,提出了一个量子签名协议.协议通过对EPR纠缠粒子对进行非正交基测量实现了签名及其验证,无需第三方存在,更加简洁可靠.由于该协议是基于量子力学的物理特性,因此具有无条件安全性.A quantum signature protocol is proposed by using only the entanglement characteristics of EPR particle pairs and quantum key distribution(QKD) technique. The protocol realizes signature and verification by performing non-orthogonal basis measurement on EPR entangled particle pairs, without the presence of a third party,which is more concise and reliable. Because the protocol is based on the physical properties of quantum mechanics,it has unconditional security.
