GPU Acceleration for FHEW/TFHE Bootstrapping

Transactions on Cryptographic Hardware and Embedded Systems
Fully Homomorphic Encryption (FHE) allows computations to be performed directly on encrypted data without decryption. Despite its great theoretical potential, the computational overhead remains a major obstacle for practical applications.

Cryptanalysis of TFHE-Friendly Cipher FRAST

IACR Transactions on Symmetric Cryptology
FRAST is a TFHE-friendly stream cipher that was published at FSE 2025. The cipher is defined over Z16, and makes extensive use of negacyclic S-boxes over Z16 as they are less costly in TFHE.

Sharing the Mask: TFHE Bootstrapping on Packed Messages

Transactions on Cryptographic Hardware and Embedded Systems
Fully Homomorphic Encryption (FHE) schemes typically experience significant data expansion during encryption, leading to increased computational costs and memory demands during homomorphic evaluations compared to their plaintext counterparts.

Improved homomorphic evaluation for hash function based on TFHE

Cybersecurity
Homomorphic evaluation of hash functions offers a solution to the challenge of data integrity authentication in the context of homomorphic encryption. The earliest attempt to achieve homomorphic evaluation of SHA-256 hash function was proposed by Mella ...

Improved FHE Bootstrapping and Its Applications in Discretized Neural Networks

IET Information Security
The inefficiency of bootstrapping is the primary bottleneck preventing fully homomorphic encryption (FHE) from practical applications. One of the main obstacles to improving the bootstrapping performance using hardware acceleration is the large storage ...

FRAST: TFHE-Friendly Cipher Based on Random S-Boxes

IACR Transactions on Symmetric Cryptology
A transciphering framework, also known as hybrid homomorphic encryption, is a practical method of combining a homomorphic encryption (HE) scheme with a symmetric cipher in the client-server model to reduce computational and communication overload on the

Fat mass and obesity-associated protein regulates arecoline-exposed oral cancer immune response through programmed cell death-ligand 1. [PDF]

Cancer Sci, 2022
PD‐L1 expression is upregulated in arecoline‐exposed OSCC cell lines and tissues and is associated with areca nut exposure. FTO promotes the stability and expression levels of PD‐L1 transcripts through modulating m6A modification and MYC, respectively.

The macrocycle inhibitor landscape of SLC-transporter. [PDF]

Mol Inform
Abstract In the past years the interest in Solute Carrier Transporters (SLC) has increased due to their potential as drug targets. At the same time, macrocycles demonstrated promising activities as therapeutic agents. However, the overall macrocycle/SLC‐transporter interaction landscape has not been fully revealed yet.
