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.

Pasta: A Case for Hybrid Homomorphic Encryption

Transactions on Cryptographic Hardware and Embedded Systems, 2023
The idea of hybrid homomorphic encryption (HHE) is to drastically reduce bandwidth requirements when using homomorphic encryption (HE) at the cost of more expensive computations in the encrypted domain.

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 ...

Generalized Bootstrapping Technique Based on Block Equality Test Algorithm

Security and Communication Networks, Volume 2018, Issue 1, 2018., 2018
With the rapid development of cloud computation and big data, the data storage and outsource computation are delegated to the untrusted cloud, which has led to a series of challenging security and privacy threats. Fully homomorphic encryption can be used to protect the privacy of cloud data and solve the trust problem of third party. The key problem of

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 ...
