ISO-IEC 18033-2 Standardizes Classic McEliece for Post-Quantum Cryptography
The ISO/IEC Committee has integrated Classic McEliece into the ISO-IEC 18033-2 standard for asymmetric ciphers to mitigate the systemic risk posed by quantum computing. Unlike RSA or ECC, which rely on integer factorization and discrete logarithms, Classic McEliece utilizes code-based cryptography based on error-correcting codes, rendering it resistant to Shor’s Algorithm. This standardization addresses the "Harvest Now, Decrypt Later" (HNDL) threat vector, where adversaries capture encrypted data for future decryption. The integration ensures global interoperability across 177 member states, providing a high-assurance benchmark for protecting long-shelf-life data in critical infrastructure, defense VPNs, and tactical systems.
