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.
