High-speed secure key distribution based on chaos synchronization and optical frequency comb technology

Secure key distribution is one of the most crucial issues for the security of communication systems. However, it is extremely challenging to realize the gigabit key distribution required for high-speed secure communication. Targeting high-speed secure key distribution, we propose a novel scheme based on chaos synchronization and optical frequency comb technology. By the multi-channel multiplexing, final security key rate is greatly extended to gigabit. The feasibility and performance of the proposed high-speed secure key distribution scheme are verified by numerical simulations.
