About Post-Quantum Cryptography

Post-Quantum Cryptography (PQC) refers to cryptographic algorithms designed to be secure against attacks by quantum computers. As quantum computing advances, traditional public-key cryptography systems like RSA and ECC will become vulnerable.

In 2024, NIST standardized the first set of post-quantum cryptographic algorithms: ML-KEM (FIPS 203) for key encapsulation, ML-DSA (FIPS 204) for digital signatures based on lattice cryptography, and SLH-DSA (FIPS 205) for hash-based digital signatures. These algorithms provide security against both classical and quantum attacks.
