Quantum Key Distribution-based Techniques in IoT

Abstract

Quantum key distribution (QKD) is a cryptographic technique that creates a secure channel of communication between two parties by applying the ideas of quantum physics. QKD ensures the confidentiality and integrity of data transmission by providing a unique key that the intended recipient can only access. Secure communication has become paramount with the proliferation of IoT (Internet of Things) devices. IoT devices have confined computational power and storage, making them vulnerable to attacks. QKD provides a safe and efficient solution for securing communication between IoT devices. This paper examines how QKD can be utilized in IoT, discussing its benefits and limitations, followed by the discussion on various QKD protocols suitable for IoT devices. In addition, the paper demonstrates that QKD is a promising solution for securing IoT communication, and its adoption significantly enhances the security and reliability of IoT networks.
