Our last session of the day: The PhD Forum—here our participants got the chance to share their research in short 5-min presentations!
Hopefully, this will help them to get connected with others working on similar topics and spark some interesting discussions this week!

I am happy to announce that my first paper has been accepted at USENIX Security!
We propose TEEcorrelate, a mitigation that statistically decorrelates reported performance counters from real ones during TEE execution.

We find that AMD does ciphertext coherence with cache line granularity, but instead 32 cache lines (half a page)!
And even crazier, it's not 32 adjacent cache lines, but they're spread over a page in varying patterns: each accessed line evicts all others in its half of the page.
