Network Management System for Quantum Key Distribution

Quantum Key Distribution (QKD) is developed to improve the security network in key exchange field. There are several success network equipments in implement QKD. However, the key distribution is limited to use in point-to-point scope. In this paper, we propose a design in quantum cryptography network that will extend the ability of number of users in present quantum cryptography network from point-to-point to multi-user network and sustain the security of the network. The developed system is implemented based on the existing quantum cryptography by managing the pairs joining of QKD system. The result of simulation is proven the feasibility to implement the proposed concept in real implementation.
