A New Trick for Polynomial Multiplication

Transactions on Cryptographic Hardware and Embedded Systems
In this paper we present a novel transformation strategy for polynomial multiplications and apply it to NTRU Prime, specifically the parameter sets sntrup761 and ntrulpr761 working in the ring Z4591[x]/⟨x761−x−1⟩.

Revisiting LWR: A Novel Reduction Through Quantum Approximations

IET Information Security, Volume 2025, Issue 1, 2025.
Pseudorandom functions (PRFs) are a very important tool in cryptography, and the learning with rounding (LWR) problem is one of the main issues in their construction. LWR problem, is to find s∈Zqn from ⌊As⌋p, where A∈Zqm×n and ⋅p:Zq→Zp is the rounding function.

Improved FHE Bootstrapping and Its Applications in Discretized Neural Networks

IET Information Security, Volume 2025, Issue 1, 2025.
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 overhead of the bootstrapping keys.

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 ...
