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😃.

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.

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.
