Thanks Stepan for presenting our paper SUIT with me at ASPLOS, it was great fun! If you're interested in secure CPU undervolting with instruction traps, find the paper here: jonasjuffinger.com/papers/suit.pdf

I recently found an exploitable timing leak in the reference implementation of Kyber (ML-KEM), the soon-to-be NIST standard for post-quantum key encapsulation. Let’s see if you can spot it in the source code - msg is secret:

Congratulations to Martin Schwarzl for winning Austria's most prestigious PhD award, the Heinz Zemanek Award! This is so well deserved. Martin is incredibly brilliant, talented, and hard-working but also one of the kindest people I know. Really happy that he receives this recognition!

We received the best paper award at AsiaCCS - Thank you and everyone involved for this award! Congratulations to all authors - especially Lukas Giner ! Try out the live demo for AsiaCCS showing WebGPU cache timings in your browser here: ginerlukas.com/asiaccs/

Join Lorenz (@hetterichlorenz) and me tomorrow at our #BHUSA briefing "Arbitrary Data Manipulation and Leakage with CPU Zero-Day Bugs on RISC-V." We'll unveil a novel architectural CPU bug that breaks all security isolations on affected RISC-V hardware. blackhat.com/us-24/briefing…

After a long embargo, I'm happy to announce the public launch of our website on our latest finding: GhostWrite. Our research uncovered a critical CPU bug that compromises all security isolations on affected RISC-V hardware. ghostwriteattack.com #GhostWrite #BlackHat #BHUSA

With the #GhostWrite CPU vulnerability, all isolation boundaries are broken - sandbox/container/VM can't prevent GhostWrite from writing and reading arbitrary physical memory on affected RISC-V CPUs. Deterministic, fast, and reliable - no side channels. ghostwriteattack.com

Diffusion Models Are Real-Time Game Engines abs: arxiv.org/abs/2408.14837 project page: gamengen.github.io Google presents GameNGen, the first game engine powered entirely by a neural model that enables real-time interaction with a complex environment over long trajectories

My time IAIK TU Graz is coming to an end. I'd like to extend a warm thank you to all my colleagues for the past 4 years! I'll definitely come by for the hard-earned alumni right to drink free coffee. ☕️

Very happy to announce that my ERC Starting Grant proposal "KEYLESS" was selected for funding by European Research Council (ERC)! We will explore new research directions on keyless cryptographic functions to improve both efficiency and security. IAIK TU Graz Computer Science & Biomedical Engineering @TUGraz TU Graz
