Post-Quantum Cryptography (PQC) Introduction
Post-Quantum Cryptography (PQC) refers to cryptographic algorithms (primarily public-key algorithms) designed to be secure against an attack by a future quantum computer. The motivation for PQC is the threat that large-scale quantum computers pose to current cryptographic systems. Today’s widely used public-key schemes – RSA, Diffie-Hellman, and elliptic-curve cryptography – rely on mathematical problems (integer factorization, discrete logarithms, etc.) that could be easily solved by…
