Happy to share this great project from Ϲhristian Knabenhans that builds off OpenFHE - Open Source Fully Homomorphic Encryption with the additional ability to prove the correct evaluation of FHE circuits using a (zero-knowledge) succinct non-interactive argument of knowldege ((zk)SNARK). Open-source FTW! github.com/zkFHE/zkOpenFH…

Excited to share this new paper with Jack O'Connor and Nick Spooner! We improve our ZK-PCP construction to cover all of NEXP (with exponential proofs), scale it to NP with polynomial proofs, and obtain O(1)-locality via composition--yielding a ZK analogue of the PCP theorem. 1/3


If you're applying for a PhD in applied crypto/system security/privacy this year, you should absolutely consider applying to Anwar Hithnawi's new lab at UoT! She's a brilliant researcher and a wonderful advisor, don't miss this opportunity to work with her.
