Abstract
In this paper, we present a network based on quantum key distribution (QKD) security. Photon has been used here to exchange keys between sender and receiver as photon possess unique quantum properties such as superposition, entanglement, and non-cloning, making them ideal for secure key exchange protocols. The proposed model integrates overlay networks with blockchain and quantum keys to ensure security against interception, cryptanalysis, including attacks from quantum computers, and provides a robust approach to key management. Additionally, Message Authentication Code (MAC) is incorporated for data authentication, using shared quantum keys. In digital signatures, quantum keys together with hash protocols are used to authenticate data between sender and receiver.
