The paper I co-authored (“A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography”) was accepted for publication by “EPJ Quantum Technology” today. 😊

You can find the preprint here, Nick will eventually update it with the final changes.

In short: We looked into existing use-cases for
#QuantumKeyDistribution and whether they make any sense and did so as a joint team between people with a QKD-background and cryptographers who started out very critical of QKD. (I’m firmly in the latter camp.)

My personal summary (though some of my co-authors won’t share it to this extend):
#QKD is bullshit and not useful for practical purposes as it stands.

SCA4PQC – die @Cyberagentur startet ein Forschungsprogramm zur Entwicklung seitenkanalresistenter Post-Quanten-Kryptographie. Ziel: Schutz vor Quantenangriffen und physischen Seitenkanalangriffen. Fokus: Cloud/Desktops, IoT und Smartcards. Forschung und Wirtschaft sind eingeladen.

Das Bild zeigt eine grafische Darstellung mit einem lila und pinkfarbenen Hintergrund, der von vielen feinen, verwobenen Linien durchzogen ist und an digitale Netzwerke erinnert. Im Vordergrund steht groß der Text „SCA4PQC“. Darunter in kleinerer Schrift: „PROGRAMM: SEITENKANALRESISTENZ IN DER POST-QUANTEN KRYPTOLOGIE“. Rechts daneben ist ein stilisiertes, weißes Symbol eines Vorhängeschlosses zu sehen, das von zwei Pfeilen umrahmt wird, die nach oben zeigen. Unten rechts ist das Logo der „Cyberagentur“ abgebildet, bestehend aus einem stilisierten C und dem Schriftzug „cyberagentur“. Die Farben sind in Violett- und Rosatönen gehalten und wirken modern und technisch. Das Bild thematisiert kryptographische Sicherheit in der Ära der Quantencomputer.

huh, that's neat. just discovered @cryspen's libcrux: github.com/cryspen/libcrux

i found it while looking for implementations of ml-kem

I had the pleasure to contribute to the #USENIX2024 paper "Divide and Surrender", recovering the full secret key from the reference implementation of the HQC Key Encapsulation Mechanism, exploiting a timing side channel arising from non-constant-time modulo operations.
Thanks to Robin Leander Schröder and Qian Guo for this opportunity and congratulations to Robin Leander Schröder for getting his first paper accepted at USENIX Security!

“This novel approach holds promise in providing robust defense against potential adversaries aiming to intercept and decrypt encrypted traffic in the future.”

@mahibi Futurezone lässt stark nach in letzter Zeit. Guck mal bei #PostQuantumCrypto, wenn dich Verschlüsselungsverfahren interessieren, die auch Quantencomputern standhalten.
