Abstract :
In the system of quantum key distribution (QKD), errors may occur in the initial keys due to system noise or eavesdropping during the transmission on quantum channel. The goal of information reconciliation is to remove these errors by exchanging messages on an authenticated public channel. In this paper, we discuss the problem of secrete key reconciliation (SKR) in QKD, analyze the cascade protocol used for SKR, then modify it according to our conclusion. Experiments have shown that the modified protocol is of much higher efficiency.
