Abstract :
In this paper, we study a key establishment scheme with quasi-cyclic (QC) low-density parity-check (LDPC) codes and universal hushing (UH) protocols. We show probabilities that different keys are shared by our error-correction and a privacy amplification scheme for a given key distribution scheme, and we propose a permutation technique that the probability becomes lower.
