【摘要】 从分析经典量子密钥分配协议——BB84协议入手,发现了其在通信效率上存在问题,并由此出发提出了一个新的改进方案。并将此方案与原方案进行比较,分析了此方案在通信效率和安全性上的变化,从实用性方面在两者之间取得了一个较好的平衡点。更多还原

【Abstract】 From analysis of the classic quantum crypt-key allotment agreement called BB84, problems existing in correspondence efficiency are discovered. A new improvement project is put forward. Compared with the original one, changes in correspondence efficiency and security are analyzed. A better equation point is found out in practicality between the two projects.更多还原
