Figure 4. Secret key and reconciled key throughput for blind reconciliation with an LDPC code of rate R₀ = 0.75.

As in Fig. 3 two different sets of parameters are chosen. The higher rate of the code increases the secret key throughput, improving on Cascade at the longest distances. This is because the rate fits appropriately the error range to be corrected. It can be seen that in the best point almost no secret key is lost with respect to the asymptotic case.
