31. What is Post-Quantum Cryptography?

    Post-Quantum Cryptography (PQC) refers to cryptographic algorithms designed to secure digital communication against attacks by quantum computers. Conventional algorithms such as RSA, Diffie–Hellman, and Elliptic Curve Cryptography (ECC) are vulnerable to Shor’s algorithm, which allows efficient factorization and discrete logarithm solving.
