Improved Programmable Bootstrapping with Larger Precision and Efficient Arithmetic Circuits for TFHE [PDF]

, 2021
Fully Homomorphic Encryption (FHE) schemes enable to compute over encrypted data. Among them, TFHE [CGGI17] has the great advantage of offering an efficient method for bootstrapping noisy ciphertexts, i.e., reduce the noise.

Differential Attacks by Algebraic Solving on a Series of HE‐Friendly Stream Ciphers

IET Information Security, Volume 2026, Issue 1, 2026.
In recent years, many symmetric encryption ciphers have been proposed for homomorphic encryption (HE) applications. Rasta and its variants Masta and Pasta have gradually become a self‐contained series of HE‐friendly stream ciphers. The feature of these ciphers is that a fresh affine layer is randomly generated for each encryption.

CRT representation of LWE Based TFHE

Computational and Applied Mathematics
Abstract Homomorphic encryption is a special type of encryption that allows you to perform homomorphic operations on encrypted data without decryption, ensuring data security. This is the most important system that needs to be developed for customer and/or patient privacy on behalf of all sectors using a cloud system.

Blockchain‐Based AI Intelligent Systems in Healthcare: A Decentralized Federated Learning Framework With Zero Trust

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Artificial intelligence (AI), blockchain (BC), and federated learning (FL) offer significant potential for strengthening data privacy, security, and decentralized decision‐making in healthcare. However, healthcare AI systems remain vulnerable to adversarial threats, including data poisoning, Byzantine behavior, Sybil attacks, and unauthorized access ...

A Bitwise Design and Implementation for Privacy‐Preserving Data Mining: From Atomic Operations to Advanced Algorithms

Security and Communication Networks, Volume 2019, Issue 1, 2019., 2019
Homomorphic encryption (HE) is considered as one of the most powerful solutions to securely protect clients’ data from malicious users and even severs in the cloud computing. However, though it is known that HE can protect the data in theory, it has not been well utilized because many operations of HE are too slow, especially multiplication.

Forschung für die Praxis: Bullöse Autoimmundermatosen unter Immuncheckpoint‐Inhibitoren

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 23, Issue 4, Page 441-446, April 2025.
Zusammenfassung Immuncheckpoint‐Rezeptoren und ‐Liganden wie das cytotoxic T‐lymphocyte‐associated Protein 4 (CTLA‐4), programmed death‐1 (PD‐1) und ligand‐1 (PD‐L1) werden sowohl auf Immun‐ als auch auf nicht‐Immunzellen in großem Umfang exprimiert und dienen der Feinabstimmung des Aktivierungsniveaus von Immunzellen, wodurch Immunreaktionen ...

Person‐centered care for older people with dementia in the acute hospital

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 4, Issue 1, Page 19-27, 2018., 2018
Abstract Introduction Patients with dementia (PWDs) are often subjected to enforced dependency and experience functional decline and emotional distress during hospital stay. Person‐centered care (PCC) with specialized psychosocial interventions, minimally obtrusive medical care, and physical restraints‐free practice holds potential to improve patient ...

Multikey Fully Homomorphic Encryption: Removing Noise Flooding in Distributed Decryption via the Smudging Lemma on Discrete Gaussian Distribution

IET Information Security, Volume 2025, Issue 1, 2025.
The current multikey fully homomorphic encryption (MKFHE) needs to add exponential noise in the distributed decryption phase to ensure the simulatability of partial decryption. Such a large noise causes the ciphertext modulus of the scheme to increase exponentially compared to the single‐key fully homomorphic encryption (FHE), further reducing the ...

Detaillierte Analyse der Bindepräferenz von Roquin an RNA‐Stammschleifen

Angewandte Chemie, Volume 136, Issue 50, December 9, 2024.
sRBNS (strukturiertes RNA Bind‐n‐Seq) ermöglicht die präzise Kartierung von RNA‐Protein‐Interaktionen inklusive RNA‐Strukturen auf Nukleotidebene. Mit dieser neuen Methode haben wir die RNA‐Bindepräferenzen von Roquin‐Proteinen gegenüber RNA‐Stammschleifen untersucht, neue hochaffine Motive identifiziert und den mRNA‐Targetraum in Zellen erweitert ...
