The quantum key reconciliation is an essential step of Quantum Key Distribution (QKD) systems for correcting error in the raw keys which happens after the transmission over a quantum channel, where two legitimate parties make their correlated bits identical by exchanging messages over the public channel. This paper presents an alternative method for error correction of quantum key reconciliation by...
The Hopper-Blum (HB) protocol, which uses noised linear parities of a shared key for authentication, has been proposed for light-weight applications such as RFID. Recently, algorithms for decoding linear codes have been specially designed for use in passive attacks on the HB protocol. These linear coding attacks have resulted in the need for long keys in the HB protocol, making the protocol too complex...
Information Reconciliation is a mechanism that allows to weed out the discrepancies between two correlated variables. It is an essential component in every key agreement protocol where the key has to be transmitted through a noisy channel. The typical case is in the satellite scenario described by Maurer in the early 90's. Recently the need has arisen in relation with Quantum Key Distribution (QKD)...
