Fully Homomorphic Encryption (FHE) ensures data confidentiality, but not integrity: Clients have no way to verify whether the results are correctly computed. While Zero-Knowledge Proofs can solve this problem, they come at a high cost—up to 10,000x more expensive than FHE.…

Excited to share our CHES 2025 paper on Fully Homomorphic Encryption (FHE)! FHE suffers from high encryption costs, and Transciphering is a technique that mitigate such costs by encrypting with some efficient symmetric encryption method (e.g., AES), then the server converts…
XOR gates are free in MPC, but how about FHE? Check our latest results😃

Mitigating racial bias from LLMs is a lot easier than removing it from humans! Can’t believe this happened at the best AI conference @NeurIPSConf We have ethical reviews for authors, but missed it for invited speakers? 😡
Proud to share our latest result in MPC: Secure vector search on 10 million dataset in 23 seconds.

Private Set Intersection (PSI) is perhaps one of the most frequently used privacy preserving techniques in production, however there are too many PSI protocols available. We wrote an ietf draft trying to standardize the simplest ECDH-PSI. datatracker.ietf.org/doc/draft-ecdh…

I love how Black Myth: Wukong starts with the Monkey King Sun Wukong fighting God Erlang Shen, the highlight of Monkey King Wrecking Havoc in Heaven, 1 of the most beloved chapter in the novel Journey to the West. It marks Wukong as the ultimate rebel

Can't wait to share our latest results in MPC: PUMA - Secure Inference of LLaMA-7B in Five Minutes ! arxiv.org/abs/2307.12533
Our new results on MPC binary circuits (three-party, honest majority) has been accepted by USENIX'Sec 2023. This is more than 3x faster than previous state-of-the-art.

This year's @IEEESSP really provides a good hybrid conference experience. Easy-to-access livestream in Whova, well adjusted network. Most of the sessions we feel no problem when listening and asking questions to remote authors. Hope other conferences could be done in this way.
