More interposer fun, this time with DDR5 memory. Breaking TDX, SGX, SEV and even Nvidia TEEs. Checkout our work at TEE.fail, and get a personally-signed Intel attestation report at @TEEdotFail.

Embarking on a new project that needs physical access to an H100 GPU. Any chance anyone is willing to let us borrow one (we promise to return it), in exchange for a security exploration into the land of confidential computing? If so, DM me for further details. Thanks :)

A great summary of the Zerocash/Zcash origin story. Truly humbled and grateful to have been a part of this, and appreciative of IEEE S&P for the recognition.
Ian Miers@secparam
Zerocash won the 2024 IEEE S&P Test of Time Award. Published in 2014, it pioneered using zkSNARKs for blockchains. Its techniques ended up in Zcash, Tornado Cash, Railgun, and other deployed protocols for private payment on public blockchains. It started with last years winner...

Congrats to @arushi1250 for successfully defending her PhD today! (My first student!) If you haven't seen it, checkout her great work on improving the security/privacy of Tor with our Bento architecture. Very proud of the work she's done and great things she'll do in the future!

@SecretShahar 👍 Yes definitely check out the post from Secret Network as well where they discuss both their response and mitigations for the vulnerability we reported, as well as planned future work.

Excited to finally release the paper we've been working on that explores the challenges of using SGX for real world applications! tl;dr, it's very hard, post-compromise recovery is hard, and we can leak secrets. Also a great resource for learning about SGX attacks and defenses!

Our survey of SGX attacks is out! Come learn about how SGX fails in real life. Check out our website sgx.fail including attacks on @SecretNetwork and @CyberLink PowerDVD.

Congrats to my student Stephen Herwig for making the paper he led “Achieving Keyless CDNs with Conclaves” reproducible! Conclaves are containers of enclaves, allowing legacy apps (even multi-process with shared memory) to be deployed in secure enclaves. Joint work with @CryptoGPS
