Security of quantum key distribution protocol with two-way classical communication assisted by one-time pad encryption
Shun Watanabe, Ryutaroh Matsumoto, Tomohiko Uyematsu
In this paper, we consider a quantum key distribution protocol (QKD) with two-way classical communication that is assisted by one-time pad encryption. We propose a two-way preproce…
