An Improved LDPC-based SEC Error Reconciliation Scheme

摘要：

　　CV-QKD has drawn many attentions due to the potential to provide high secret key rate and low cost.Error reconciliation is the key module of post processing of a CV-QKD system.In this paper,an improved LDPC-based SEC error reconciliation scheme is proposed.Through the optimization of inner-level decoding and reduction of the iteration rounds of inter–level decoding,the reconciliation can be accelerated evidently.Simulation results show that the proposed scheme can improve the reconciliation rate to 16.55kbps with the reconciliation efficiency of 91.8% when SNR is 4.5dB.
