提出一种简单而有效的量子密钥分配协议(简称为SEQDKD)。协议基于单偏振光子系统，实现了高效率的量子密钥分配任务。并针对不同的协议情况而采用不同的效率计算方法，更加科学。相较于常见的量子密钥分配协议而言，本协议达到了高的密钥分配效率并且易于实现。更重要的是，理论论证表明，该协议对于截获重发攻击是安全的。 A simple and efficient quantum key distribution protocol (called SEQDKD) is proposed. Based on the single polarization photon system, the protocol can efficiently realize the quantum key distribution. Meantime, it is more scientific that we use different efficiency calculation methods to measure the efficiency of different protocols. Compared with other common quantum key distribution protocols, our protocol is more efficient and easier to implement. More importantly, this protocol is theoretically proved to be secure against the intercept-resend attack.
