Enhancing Cloud Security through Quantum Cryptography for Robust Data Transmission

Abstract

The exponential growth of data transmission in cloud environments has heightened the need for robust security measures to protect sensitive information from cyber threats. Quantum cryptography, leveraging the principles of quantum mechanics, offers a revolutionary approach to securing data transmission through its unique capabilities of quantum key distribution (QKD). This paper explores the integration of quantum cryptography in cloud environments, examining its potential to enhance data security, confidentiality, and integrity. By providing an unbreakable encryption method based on the fundamental laws of physics, quantum cryptography mitigates risks associated with classical cryptographic techniques vulnerable to advances in computational power and algorithms. The study presents a comprehensive analysis of various quantum cryptographic protocols, such as BB84 and E91, and evaluates their performance and applicability in cloud-based systems. Additionally, we discuss the challenges and limitations of implementing quantum cryptography in real-world cloud infrastructures, including hardware requirements, network compatibility, and scalability. The paper concludes with recommendations for integrating quantum cryptography into existing security frameworks, ensuring that organizations can leverage this cutting-edge technology to achieve secure data transmission in increasingly complex and interconnected cloud environments
