A data aggregation protocol based on TFHE [PDF]

open access: yesInternational Journal of Computer Mathematics: Computer Systems Theory
Torus Fully Homomorphic Encryption (TFHE) is a probabilistic cryptosytem over the real torus which allows one to operate directly on encrypted data without first decrypting them. We present an aggregation protocol based on a variant of TFHE for computing the sum of sensitive data, working only with the corresponding ciphertexts.

Integerwise Functional Bootstrapping on TFHE

Lecture Notes in Computer Science, 2020
We propose a new technique for implementing an arbitrary 1-variable function during a bootstrapping procedure based on an integerwise variant of the fully homomorphic encryption scheme TFHE. The integerwise TFHE was implicit in the original TFHE paper (Asiacrypt’ 2016), and Bourse et al. provided an explicit form (CRYPTO’ 2018).

Building Blocks for LSTM Homomorphic Evaluation with TFHE

open access: yesLecture Notes in Computer Science, 2023
Long Short-Term Memory (LSTM) is a Neural Network (NN) type that creates temporal connections between its nodes. It models sequence data for applications such as speech recognition, image captioning, DNA sequence analysis, and sentence translation. Applications that are often subject to privacy constraints.
