Analysis For Device Independent Quantum Key Distribution Based On The Law Of Large Number
Measuring device-independent quantum key distribution scheme can remove all detectors side-channel flaw,combined with decoy state program to achieve absolute security of quantum key distribution.In this paper,the statistical law of large numbers fluctuate limited key length measuring device- independent quantum key distribution scheme in single-photon counting rate and BER (Bit Error Rate) were analyzed,and the key length of the single-photon N = 106~1012 counting rate and the key generation rate simulation were performed.Simulation results show that: in the optical fiber transmission,with decreasing key length 300km,the secure transmission distance,decreased respectively to 260km ( N = 1010 ) and 75km ( N =106 ).When N =1012,secure transmission distance is reached at 295km,close to the theoretical limit.
