METHOD FOR PROCESSING DOUBLE CLICK EVENT FOR SECURING SAFETY IN QUANTUM KEY DISTRIBUTION SYSTEM

摘要

A method performed by a processor of a receiver of generating a secret key using a quantum communication, the processor execute the method comprising: performing a quantum key distribution (QKD) protocol to generate a sifted key; performing a post-processing protocol based on the sifted key to generate a final key; counting the number of double click events when quantum signals are detected; and performing privacy amplification of the final key based on the counted number of the double click events.
