Efficient and Compact Full-Domain Functional Bootstrapping via Subring Folding

open access: yesTransactions on Cryptographic Hardware and Embedded Systems
Functional bootstrapping has emerged as a powerful tool in fully homomorphic encryption (FHE), integrating noise reduction and function evaluation. FHEW/TFHE-based functional bootstrapping has demonstrated high efficiency in evaluating arbitrary non ...

Accelerated Multi-Key Homomorphic Encryption via Automorphism-Based Circuit Bootstrapping

open access: yesIEEE Access
In FHEW-like bootstrapping, blind rotation is based on the CMUX Gate (The CMux gate is a controlled selector gate that uses a control input to choose between two data inputs for the output), and blind rotation based on automorphism (A bijective ...

Fast Transciphering Via Batched And Reconfigurable LUT Evaluation

open access: yesTransactions on Cryptographic Hardware and Embedded Systems
Fully homomorphic encryption provides a way to perform computations in a privacy preserving manner. However, despite years of optimization, modern methods may still be too computationally expensive for devices limited by speed or memory constraints.

New Techniques for Multi-value Input Homomorphic Evaluation and Applications [PDF]

open access: yes, 2019
In this paper, we propose a new technique to perform several homomorphic operations in one bootstrapping call over a multi-value plaintext space. Our construction relies on the FHEW-based gate bootstrapping; we analyze its structure and propose a ...

General Bootstrapping Approach for RLWE-based Homomorphic Encryption [PDF]

open access: yes, 2021
We propose a new bootstrapping approach that works for all three Brakerski-Gentry-Vaikuntanathan (BGV), Brakerski/Fan-Vercauteren (BFV), and Cheon-Kim-Kim-Song (CKKS) schemes. This approach adopts a blind rotation technique from FHEW-type schemes.

Bootstrapping in FHEW-like Cryptosystems [PDF]

open access: yes
FHEW and TFHE are fully homomorphic encryption (FHE) cryptosystems that can evaluate arbitrary Boolean circuits on encrypted data by bootstrapping after each gate evaluation. The FHEW cryptosystem was originally designed based on standard (Ring, circular

PEGASUS: Bridging Polynomial and Non-polynomial Evaluations in Homomorphic Encryption [PDF]

open access: yes, 2020
Homomorphic encryption (HE) is considered as one of the most important primitives for privacy-preserving applications. However, an efficient approach to evaluate both polynomial and non-polynomial functions on encrypted data is still absent, which ...
