Quantum Key Distribution Network Based on Differential Phase Shift
Wanying Wang, Chuan Xi Wang, Wen Kai, Long Gui-Lu · Chinese Physics Letters · 2007
Using a series of quantum correlated photon pairs, we propose a theoretical scheme for any-to-any multi-user quantum key distribution network based on differential phase shift. The differential phase shift and the different detection time slots ensure the security of our scheme against eavesdropping. We discuss the security under the intercept–resend attack and the source replacement attack.
