ePrint Report: Circuit Privacy for FHEW/TFHE-Style Fully Homomorphic Encryption in Practice

Kamil Kluczniak

A fully homomorphic encryption (FHE) scheme allows a client to encrypt and delegate its data to a server that performs computation on the encrypted data that the client can then decrypt. While FHE gives confidentiality to clients' data, it does not protect the server's input and computation. Nevertheless, FHE schemes are still helpful in building delegation protocols that reduce communication complexity, as FHE ciphertext's size is independent …
