The Role of Quantum Cryptography in Enhancing Cybersecurity.
Chris Gilbert, Mercy Abiola Gilbert · International Journal of Research Publication and Reviews · 2024
As quantum computing starts to pose significant security risks to traditional cryptographic systems, quantum cryptography is emerging as a key solution.This paper examines how quantum key distribution (QKD) and other quantum-based cryptographic methods can strengthen cybersecurity.By leveraging principles from quantum mechanics-like superposition and entanglement-quantum cryptography offers the potential to protect communications from highly advanced quantum threats.We delve into various quantum cryptographic protocols, including BB84 and device-independent QKD, exploring them both theoretically and through computational analysis.Real-world applications in sectors such as finance and telecommunications demonstrate the practical value of QKD.However, challenges like high costs, scalability issues, and compatibility with existing systems remain obstacles to broader implementation.Ultimately, this research underscores how quantum cryptography can enhance current security measures and meet the demands of a future shaped by quantum computing.
