摘　　要：针对BB84协议对存在窃听的有噪信道中进行量子密钥分配效率不高的问题,提出一种改进方案。新方案在发送方与接收方都加入类似签名的过程,能够很好地判断窃听的存在,并且窃听者只能获取少量的密钥信息,在保障传输过程安全的同时,提高了量子密钥分配的效率。In order to solve the low transmission efficiency problem of the BB84 protocol in the noisy channel with wiretap in- side, this paper proposed an improved scheme. The new scheme added a process, similar to signature, to the sender and the receiver, was able to judge the existence of eavesdropping, and the eavesdropper could only get a small amount of key informa- tion. So, the new scheme ensures the safety of the transmission process, at the same time, improves the.efficiency of the quan- tum key distribution.
