Quantum Cryptography: Enhancing Secure Communication in the Era of Quantum Computing

The current research focuses on quantum cryptography as a suitable solution of communication security given the growing quantum computing threat. Since RSA and ECC algorithms are becoming more and more susceptible to quantum algorithms, new quantum-resistant algorithms are required. In present work, an empirical and theoretical analysis is applied to assess the efficiency of QKD protocols – BB84 and Continuous Variable QKD – compared to the established CSPs. Some of the key findings include demonstrating provable security of information via QKD, defending against eavesdropping compared to failing classical systems. The future applications of quantum cryptography are described in organizations and areas of concern like health and finance, to secure and improve security and regulatory procedures. Also, the work seeks to look at the parity between classical and quantum computing structures with blended approaches as a more viable approach to scaling up. Solving integration and scalability issues, this research lays a foundation for implementing quantum cryptography around the world during the digital era.
