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.

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 ...
