Abstract

We present a quantum key generation and distribution scheme that utilizes a frequency-comb signal source for key encryption, data encoding and transmission between network users. In this scheme, a frequency is selected randomly from the set of comb frequencies and assigned to a user. Furthermore, another random method is used to encode the randomly selected frequency with user data for key generation. As a result, the key generation is robust against attacks. We shall present practical method for the frequency comb generation and determine the efficiency of the scheme against malicious multiple attacks.
