The Algorithms Already Exist: Why Post-Quantum Security Is Now a Migration Problem.

The post-quantum security problem has changed. The hard frontier is increasingly operational migration rather than invention of the first usable algorithms.

Module 1 — The Cryptography Problem Has Changed

The First Standards Are Ready. Deployment Is the New Work.

NIST has finalized three foundational PQC standards that are ready for implementation.

The first implementation-ready building blocks already exist; migration is now a coordination problem.

Real-world analogy

Standards solve specification; migration solves the installed base.

FIPS 203 · ML-KEMFIPS 204 · ML-DSAFIPS 205 · SLH-DSA
Practice Case 1
Which statement best reflects the current transition?
Practice Case 2
What does ML-KEM primarily standardize?
Practice Case 3
Why is that misleading?
Module 2 — You Cannot Migrate What You Cannot See

Cryptographic Inventory Becomes Security Infrastructure

Migration begins with visibility: where is cryptography actually used?

Unknown cryptographic dependencies become migration risk.

Risk lens: Long-lived sensitive data may deserve earlier priority.
Practice Case 4
What is the strongest first step?
Practice Case 5
Which deserves higher attention?
Practice Case 6
Which belongs in the inventory?
Module 3 — Interoperability Is Where Migration Gets Real

A Secure Algorithm Can Still Fail as a Deployment

Security properties do not eliminate integration problems.

Migration is often incremental, not a single switch-flip.

Crypto agility: Design migration so the next cryptographic change is less painful.
Practice Case 7
What kind of problem is this?
Practice Case 8
Why test first?
Practice Case 9
What does crypto agility improve?
Module 4 — The Coordination Problem

The Slowest Dependency Can Define the Migration Timeline

Migration speed is constrained by ecosystems, not only cryptographers.

Uncertain arrival time and long migration time can coexist.

Operational thesis: The hard part is orchestrating the whole transition.
