We're on our way to Germany for the AMD Security Working Group.
We'll be showcasing a demo of a side channel attack targeting ML-KEM on an STM32, and how we approach hardware investigations.

In Zukunft wird OpenPGP – und damit auch mein PGP-Keygen – die folgenden Post-Quantum-Cryptography (PQC)-Algorithmen unterstützen, sobald der aktuelle IETF-Draft (draft-ietf-openpgp-pqc-14) als RFC veröffentlicht wird.

Diese Algorithmen wurden vom NIST standardisiert und sind für die Integration in OpenPGP vorgesehen:

➡️ ML-KEM (ehemals CRYSTALS-Kyber)
➡️ ML-DSA (ehemals CRYSTALS-Dilithium)
➡️ SLH-DSA (ehemals SPHINCS+)

Die Bilder, die ich erstellt habe, geben einen Überblick über die Verwendung und Sicherheitsniveaus der Algorithmen.

I think the best summary until now about Post-quantum cryptography is from Peter Gutmann in the cryptography mailing-list.

Given that after 20 years and hundreds of millions of dollars spent researchers have yet to demonstrate a single legitimate cryptanalysis result using a quantum physics experiment, it's a bit like arguing over which brand of unicorn repellent is the most cromulent.

The current state of things in terms of pure vs. hybrid systems seems to be:

- Governments = Pure: “We’re putting all our eggs in one basket and hoping that the dial stops spinning at ‘not broken’”

- Everyone else = Hybrid: “We trust this new stuff so little that we’re requiring you use the crypto that we claim is broken alongside it”

Peter.

Did I just spend almost 3 hours watching a video on post-quantum cryptography? This video is so well made and unfortunately the algorithm won't push it to people because of its length.

Everyone thought the “hedged” mode of ML-DSA (Dilithium) fixed fault attacks. New research presented at CHES shows that’s not the case. A "fault then correct" trick still works.

We break it down in our latest Expert Review. ➡️ eshard.com/posts/expert-review

Why upgrade to Red Hat Enterprise Linux 9.6 or 10 now?

Every Linux distro is out there to scratch a certain itch. For a lot of of organization the choice is Red Hat Enterprise Linux or . I'd like to share this blog from my colleague Gil Cattelain on some of the compelling capabilities in our latest releases.
