While cryptographically relevant quantum computers (CRQCs) capable of breaking RSA-2048 and Elliptic Curve Cryptography via Shor’s Algorithm remain years away, adversaries are currently executing “Harvest Now, Decrypt Later” (HNDL) data exfiltration attacks.
Encrypted governmental records, corporate intellectual property, and medical archives intercepted today can simply be archived on cold storage, awaiting quantum decryption capabilities in the 2030s.
The Standardized Algorithms: ML-KEM and ML-DSA
The National Institute of Standards and Technology (NIST) recently finalized the first wave of post-quantum standards based primarily on the hardness of high-dimensional lattice math problems:
- ML-KEM (formerly Kyber): General encryption and key establishment mechanism with compact public key sizes (~1,184 bytes).
- ML-DSA (formerly Dilithium): Digital signature generation providing tamper-evident authenticity across code signing and TLS handshakes.
Enterprises must conduct comprehensive crypto-agility audits across their public key infrastructure (PKI), updating hardware security modules (HSMs) and mutual TLS certificates to hybrid post-quantum cipher suites.
