I am happy to announce that my first paper has been accepted at USENIX Security!

I'm very happy to announce our new Cohere+Reload: Re-enabling High-Resolution Cache Attacks on AMD SEV-SNP was accepted at DIMVA 2025!

In it @snee.la, @gruss.cc and I investigate AMD's ciphertext coherence mechanism and show even low resolution leakage can go a long way.

1st Microarchitecture Security Conference (uASC '25)

Got some negative or unrealistic threat model results that still bring interesting insights? A side channel that requires root to leak something from the kernel? Reproducing prior work? Somewhat related to microarchitecture? Here's your venue: uasc.cc
