摘 要:Measurement-device-independent quantum key distribution(MDI-QKD)provides us a powerful approach to resist all attacks at detection *** the unconditional security,people also seek for high key generation rate,but MDI-QKD has relatively low key generation *** this paper,we provide an efficient approach to increase the key generation rate of MDI-QKD by adopting multiple degrees of freedom(DOFs)of single photons to generate *** with other high-dimension MDI-QKD protocols encoding in one DOF,our protocol is more flexible,for our protocol generating keys in independent subsystems and the detection failure or error in a DOF not affecting the information encoding in other *** on above features,our MDI-QKD protocol may have potential application in future quantum comniunication field.
