    Quantum Vulnerabilities in Today’s Cryptography

    A Historical Perspective and a Forward-Looking Defense Strategy For decades, modern cryptography has relied on mathematical problems assumed to be computationally infeasible for classical computers. Algorithms like RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) derive their security from the hardness of factoring large integers or solving discrete logarithms. This design has worked because no…

    Post-Quantum Cryptography: The Final Digital Defense Line

    The rapid progress of quantum computing has forced a major shift in the foundations of modern cybersecurity. Today’s most widely used cryptographic systems — RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) — were designed under the assumption that certain mathematical problems require an impractical amount of time to solve. Quantum computers break that assumption.…
