Symmetric blind information reconciliation and hash-function-based verification for quantum key distribution
We consider an information reconciliation protocol for quantum key
distribution (QKD). In order to correct down the error rate, we suggest a
method, which is based on symmetric blind information reconciliation for the
low-density parity-check (LDPC) codes. We develop a subsequent verification
protocol with the use of -universal hash functions, which allows
verifying the identity between the keys with a certain probability.Comment: 4 pages; 1 figure; published versio
