Secure Communication System Using Quantum Cryptography

Authors- S. Bala Chandran, Dr. S. Prasanna

Abstract--Quantum cryptography offers an attack-proof model for communication that is resistant to quantum computing advances. This study proposes a hybrid model that unifies Quantum Key Distribution (QKD) with Post-Quantum Cryptography (PQC) to ensure security in diverse networks. Efficient key distribution, life-cycle management, and performance monitoring are facilitated through a collaborative Quantum Key Management System (QKMS) and Q-controller. By having QKD in the center and using PQC in the user terminals, this model overcomes the limitations based on the range and expense of QKD. Scalable, fault-tolerant, and end-to-end secure communications are made possible by the proposed approach.
