Paper Abstract

Secret keys can be established through the use of a Quantum channel monitored through classical channel which can be thought of as being error free. The quantum channel is subject to massive erasures and discards of erroneously measured bit values and as a result the error correction mechanism to be used must be accordingly modified. This paper addresses the impact of error correction (known as Reconciliation) on the secrecy of the retained bits and issues concerning the efficient software implementation of the Low Density Parity Check algorithm in the Quantum Key Distribution environment. The performance of three algorithmic variants are measured through implementations and the collected sample data suggest that the implementation details are particularly important
