Where Every Country Stands on Post-Quantum Migration
More than a dozen national authorities have published post-quantum deadlines. They agree on 2035 and disagree on almost everything before it. A field guide…
Why the World Can’t Agree on Hybrid PQC Deployment
Germany expects hybrid key exchange. Australia expects pure ML-KEM. The US sets a date for dropping the classical half. What to build when the…
The Two Dates in NIST IR 8547 That Govern Your Migration Plan
NIST IR 8547 is usually reduced to 2035. It sets two dates, and the earlier one is already shaping procurement and risk acceptance decisions.
The Four Axes Where National PQC Requirements Diverge
Approved algorithm lists are the first of four axes on which national post-quantum requirements diverge. The other three are harder to abstract away.
How Hybrid Cryptography Works, Byte by Byte
Hybrid key exchange and dual signatures, explained from the combiner outward: what goes into the KDF, what the extra kilobytes cost, and how to…
Quantum Key Distribution, Read as a Security Control
Three national agencies advise against QKD for their own networks. Twenty-seven EU states are funding one. Both positions hold, and the reason explains how…
Why You Can’t Just Drop In Post-Quantum Cryptography
The algorithms are standardised. The plumbing around them was sized for 32-byte keys. Here is where post-quantum objects break real infrastructure, and what to…
Why Telecom PQC Migration Is Harder Than Enterprise Migration
Operators face two problems enterprises mostly don't: most of their cryptography is written by someone else, and every cryptographic relationship has a counterparty they…
Crypto-Agility When You Can’t Swap the Algorithm
Algorithm swaps almost never happen cleanly. A more useful definition of crypto-agility, and the four mitigation patterns architects can deploy before a full replacement…
Where Trust Sits in a Quantum Network
Quantum key distribution moves the trust boundary rather than removing it. A working guide to trusted nodes, device-level attacks, and the questions to ask…
