Abstract :
Quantum key distribution (QKD) provides unconditional physical layer security for the distribution of encryption keys between legitimate parties. This paper presents a quantum key distribution protocol over a two-way quantum channel. This protocol does not require any classical communication channel for key sifting and key reconciliation. Utilizing the proposed protocol, one can reduce the overhead in the classical channel and increase the speed with which keys can be exchanged. Absence of a classical communication channel reduces operational overhead.
