Migrating to quantum safe crypto -

### Engineering Strategies for Post-Quantum Migration At 00:00, Christian Paquin from Microsoft Research presents on preparing enterprise software architectures for the post-quantum cryptographic transition at the Crypto and Privacy Village. Paquin outlines the timeline and engineering hurdles facing secure communications.

### Cryptographic Agility in Enterprise Software At 05:20, Paquin emphasizes the necessity of cryptographic agility. He explains that systems must be designed to swap cryptographic algorithms dynamically without requiring major software redesigns, drawing parallels to historical migrations from MD5 to SHA-256 and TLS version upgrades.

### Hybrid Post-Quantum Key Exchange Architectures At 10:29, the presentation explores hybrid cryptographic protocols. By pairing classical elliptic curve Diffie-Hellman (ECDH) algorithms with post-quantum lattice or isogeny-based algorithms (such as SIKE or Kyber), organizations ensure communications remain secure against future quantum decryption without sacrificing current classical security guarantees.

### Tracking the NIST Post-Quantum Standardization Effort At 15:24, Paquin reviews the status of the ongoing NIST post-quantum standardization process. He evaluates leading candidate algorithms across lattice-based, code-based, and multivariate mathematical families, detailing performance trade-offs in key size and computational latency.

### Prototyping Post-Quantum TLS with Open-Source Tooling Concluding between 20:52 and 25:30, the speaker details open-source testing platforms, highlighting the Open Quantum Safe (OQS) project and post-quantum OpenSSL forks. He demonstrates how developers can benchmark post-quantum TLS handshakes across realistic network environments today.
