Quantum Key Distribution in the Era of Cybersecurity Threats: A Forward-Looking Perspective

Abstract

The necessity for sophisticated security solutions that can shield sensitive data from changing threats has been highlighted by the development in complex cyberthreats. Despite being the cornerstone of today's cybersecurity architecture, traditional cryptographic systems are seriously vulnerable to the development of quantum computing, which might jeopardize encryption techniques like RSA and ECC. By utilizing quantum physics, Quantum Key Distribution (QKD) offers a novel method for ensuring secure communication that was previously impervious to eavesdropping. The ideas, protocols, and benefits of QKD are thoroughly examined in this work, which also emphasizes how it may be used to solve cybersecurity issues brought on by quantum developments. By examining the limitations of classical cryptographic systems and the capabilities of QKD, this research emphasizes the necessity of adopting quantum-resistant solutions to secure data in an increasingly digital and quantum-aware world.
