Transciphering, Using FiLIP and TFHE for an Efficient Delegation of Computation
, 2020 Improved filter permutators are designed to build stream ciphers that can be efficiently evaluated homomorphically. So far the transciphering with such ciphers has been implemented with homomorphic schemes from the second generation. In theory the third generation is more adapted for the particular design of these ciphers.

Faster NTRU-based Bootstrapping in less than 4 ms
Transactions on Cryptographic Hardware and Embedded SystemsBootstrapping is a critical technique in constructing fully homomorphic encryption (FHE), which serves to refresh the noise in FHE ciphertexts, enabling an arbitrary number of homomorphic operations.

Towards a Functionally Complete and Parameterizable TFHE Processor
CoRRFully homomorphic encryption allows the evaluation of arbitrary functions on encrypted data. It can be leveraged to secure outsourced and multiparty computation. TFHE is a fast torus-based fully homomorphic encryption scheme that allows both linear operations, as well as the evaluation of arbitrary non-linear functions.

Hitchhiker's guide to a practical automated TFHE parameter setup for custom applications [PDF]
, 2022 Also referred to as the Holy Grail of Cryptography, Fully Homomorphic Encryption (FHE) allows for arbitrary calculations over encrypted data. As a basic use-case, FHE enables a User to delegate a computation over her sensitive data to a semi-trusted ...

Optimized Homomorphic Evaluation of Boolean Functions
Transactions on Cryptographic Hardware and Embedded SystemsWe propose a new framework to homomorphically evaluate Boolean functions using the Torus Fully Homomorphic Encryption (TFHE) scheme. Compared to previous approaches focusing on Boolean gates, our technique can evaluate more complex Boolean functions ...
