Post-Quantum Secure Authentication Methods Suitable For Quantum Key Distribution

QKD occurs over two communication channels: classical and quantum. While the quantum channel is somewhat secure by quantum principles, the classical channel need to be authenticated using cryptographic algorithms. Unfortunately, the authentication algorithms and the methods suggested are not taking into consideration the problems practical implementations are facing. Moreover, there are areas which has not been discussed by the literature such as the quantum application layer in communication over classical channel. This study identifies the hurdles practical implementations of QKD are facing and proposes a solution which take into consideration these needs. Moreover, it suggests new protocols and approaches suitable for QKD post processing authentication.
