Enhancing Database Security Through Quantum Cryptography: A Research Perspective

Abstract

In the age of quantum computing, classical cryptographic techniques are under increasing threat. Quantum cryptography offers an innovative method for data protection by utilizing the principles of quantum mechanics to achieve unbreakable encryption. With the escalating volume of sensitive information stored in databases, conventional cryptographic techniques are becoming more vulnerable, particularly in light of advancements in quantum computing. This paper explores the application of Quantum Key Distribution (QKD) and quantum cryptographic techniques into database systems to bolster security. By implementing the BB84 protocol and quantum encryption, we propose a secure data communication framework that prevents eavesdropping and data tampering. The study evaluates the feasibility of integrating QKD with existing database systems, demonstrates a simulated implementation using Python, and compares its resilience to classical attacks. Results indicate significant improvement in confidentiality and key exchange security, marking a step toward quantum-resilient database systems.
