提出了基于单光子的单向量子安全通信方案.发送方在对信息序列进行编码操作之前首先将其和随机序列进行异或操作并插入校验序列.接收方收到光子后对其进行延迟,此后发送方公布编码基从而使接收方在正确的基下进行测量.接着双方通过校验序列判断信道的安全性,如果信道安全,则发送方公布接收方有测量结果的位置所对应的随机序列,接收方由此恢复出信息序列;如果信道不安全,窃听者所获得的只是随机的发送序列,信息序列仍然是安全的.此协议与双向通信协议相比具有传输效率高、易于实现等优点.
A one-photon-based one-way quantum secure communication scheme is proposed, in which the sender first XORs the random sequence with the random sequence and inserts it into the check sequence before the sender encodes the information sequence, the receiver delays the received photon, Afterwards, the sender publishes the encoding base so that the receiver can measure at the correct base, and then both sides judge the channel security through the check sequence. If the channel is secure, the sender publishes the random sequence corresponding to the location where the receiver has the measurement result , So the receiver can restore the message sequence. If the channel is not secure, the eavesdropper only obtains the random sequence, and the message sequence is still secure. Compared with the bidirectional communication protocol, this protocol has the advantages of high transmission efficiency and easy implementation .
