METHOD FOR ENHANCING SECURITY OF SECRET KEY GENERATED IN QUANTUM KEY DISTRIBUTION SYSTEM

摘要

Disclosed is a method for enhancing the safety of a secret key generated in a quantum key distribution (QKD) system. According to an aspect of the embodiment, the QKD system generating the secret key with the enhanced safety, comprises a transmission apparatus and a reception apparatus which generates a key which is sifted and encrypted by performing a predetermined random number sequence operation and a bitwise exclusive OR operation of the sifted key and generates a secret key by performing a post-processing operation of the key which is encrypted and sifted.
