Sync-Sequence based Synchronization Scheme in QKD-Secured Access Networks
Nowadays, more and more attention has been paid to the information security of access network, so the application of quantum key distribution (QKD) technology in access network has gradually become a feasible scheme. However, with the application of QKD technology in access network, the support of synchronization technology becomes more important. This paper provides a synchronization scheme in QKD-Secured access network scenario and realizes the synchronization function. Based on this, a sync-sequence based synchronization scheme is proposed to reduce the synchronization error of the system, and then reduce the probability of encrypted service transmission failure caused by non-synchronization.
