Key generation schemes for channel authentication in quantum key distribution protocol

Abstract Quantum key distribution (QKD) systems enable secure key generation between two parties. Such systems require an authenticated classical channel for QKD protocols to work. Usually, the initial authentication key for this channel is pre‐shared. In this work, methods that are used to renew th...
