- Post-Quantum Cryptography: The Algorithms Replacing RSA Before the Quantum Computer Arrives
Every TLS connection, every signed certificate, every encrypted email uses cryptography that Shor's algorithm can break. NIST finalised four post-quantum cryptographic standards in 2024 — ML-KEM, ML-DSA, SLH-DSA, and FN-DSA — based on mathematical problems that quantum computers are not known to solve efficiently. Here is the threat model, the mathematics, the size trade-offs, and why migration is already urgent even though the quantum computer does not exist yet.
- Harvest Now, Decrypt Later: The Quantum Threat Reshaping Global Cryptography
Every encrypted message sent today could be stored by adversaries and decrypted once a sufficiently powerful quantum computer exists. The window to act is narrowing — here is what the world is doing about it.
