Post-Quantum Cryptography Migration at Meta: Framework, Lessons, and Takeaways
Quantum computing is expected to break today's public-key cryptography, creating immediate “store now, decrypt later” risk for sensitive data. NIST and the UK NCSC are pushing migration timelines toward 2030, and first standards like ML-KEM (Kyber) and ML-DSA (Dilithium) are now published, with HQC also selected. Meta says it is already rolling out post-quantum encryption internally and recommends a staged approach: crypto inventorying, application risk prioritization, and hybrid deployment to reduce exposure while standards mature.
