循环差分相移量子密钥分发协议研究
Round-robin differential phase-shift quantum key distribution protocol
摘要
Abstract
The quantum key distribution(QKD) has allowed the authorized users to share an absolute secret key,while providing the detection of eavesdropping.It is an important research area in information security during recent 30 years.In the conventional QKD protocol,the secure key is depend on the estimation of the interference caused by the eavesdropper's eavesdropping,that is,when the quantum bit error rate estimated from the interference is greater than the threshold,the authorized users discard the key generated from the QKD procedure.The round-robin differential phase-shift (RRDPS)-QKD protocol proposed in 2014 could be guaranteed without monitoring the eavesdropper's disturbances.It becomes a hot topic due to its high tolerance for noises.The RRDPS-QKD protocol is presented by its principle,modifications,and development protocol in the experiment.Finally,researches on RRDPS-QKD protocol are introduced.关键词
