Fherret: Proof of FHE Correct-and-Honest Evaluation with Circuit Privacy from MPCitH
Cryptology ePrint Archive, 2025
J. Huth, A. Joux, G. Santato
A novel proof system based on MPC-in-the-Head that protects FHE clients from reaction-based attacks while preserving circuit privacy.

Dimensional eROSion: Improving the ROS Attack with Decomposition in Higher Bases
Cryptology ePrint Archive, 2025
A. Joux, J. Loss, G. Santato
We extend the polynomial ROS attack to work in lower dimensions using higher-base decompositions and some LLL magic.

On Circuit Private, Multikey and Threshold Approximate Homomorphic Encryption
IACR Communications in Cryptology, vol 2, issue 1
K. Kluczniak, G. Santato
We analyze how to achieve circuit privacy in approximate FHE and security in multiparty approximate FHE with noise flooding by proving that strong noise is essential, and encrypting the function is not adding security.
