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.

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.
