Ring packing and amortized FHEW bootstrapping [PDF]
, 2019 The FHEW fully homomorphic encryption scheme (Ducas and Micciancio, Eurocrypt 2015) offers very fast homomorphic NAND-gate computations (on encrypted data) and a relatively fast refreshing procedure that allows to homomorphically evaluate arbitrary NAND ...

Bootstrapping in FHEW-like Cryptosystems [PDF]
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

Accelerated Multi-Key Homomorphic Encryption via Automorphism-Based Circuit Bootstrapping
IEEE AccessIn 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
Transactions on Cryptographic Hardware and Embedded SystemsFully 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.

Circuit Privacy for FHEW/TFHE-Style Fully Homomorphic Encryption in Practice
IACR Communications in CryptologyA 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.

FHEW 계열 동형암호에서의 빠른 블라인드 로테이션에 대한 연구
학위논문(석사) - 한국과학기술원 : 정보보호대학원, 2024.8,[iv, 28 p. :]Homomorphic encryption allows for operations on ciphertexts, and due to its design characteristics, errors accumulate in the ciphertexts during operations. Therefore, after a certain number of operations,

Fast Blind Rotation for Bootstrapping FHEs [PDF]
Blind rotation is one of the key techniques to construct fully homomorphic encryptions with the best known bootstrapping algorithms running in less than one second. Currently, the two main approaches, namely, AP and GINX, for realizing blind rotation are

Unbounded Multi-Hop Proxy Re-Encryption with HRA Security: An LWE-Based Optimization [PDF]
Proxy re-encryption (PRE) schemes enable a semi-honest proxy to transform a ciphertext of one user $i$ to another user $j$ while preserving the privacy of the underlying message.
