WebNTRU problems from the perspective of actual attacks, and whether there are worst-case to average-case reductions for NTRU problems like other lattice-based problems (e.g., the Ring-LWE problem) is still an open problem. In this paper, we show that for any algebraic number field , the NTRU problem with suitable parameters defined over the ring of WebThe 25 year-old NTRU problem is an important computational assumption in public-key cryptography. However, from a reduction perspective, its relative hardness compared to other problems on Euclidean lattices is not well-understood. Its decision version reduces to the search Ring-LWE problem, but this only provides a hardness upper bound.
