The Future of Cyber Security Policy in the Post-Quantum Era

Abstract

The advent of quantum computing presents unprecedented challenges to the existing cybersecurity framework, especially in the realm of cryptographic algorithms. Current encryption methods, such as RSA and ECC, which secure sensitive data, are vulnerable to quantum-based attacks due to the capabilities of quantum algorithms like Shor’s and Grover’s. This research paper explores the future of cybersecurity policy in the post-quantum era, analyzing the gaps in current policies and the need for quantum-resistant solutions. By examining emerging cryptographic algorithms, including lattice-based and hash-based cryptography, this study underscores the necessity for governments and industries to collaborate in developing post-quantum cryptographic standards. Furthermore, the paper addresses the economic and ethical considerations of transitioning to quantum-safe systems and provides case studies to illustrate the real-world implications of quantum threats on critical sectors such as finance, national security, and cloud computing. Ultimately, the study advocates for an adaptable, globally coordinated policy framework to ensure resilient cybersecurity in the quantum age.
