On the hardness of ntru problems
WebThe hardness of the NTRU and Ring-LWE problem directly depends on the degree of the polynomial f(X). Based on the current state of knowledge, obtaining 128-256 bit hardness requires taking dimensions somewhere between 512 and 1024. Since there are no powers of 2 in between, and because one may need to go beyond 1024 in Web14 de jun. de 2024 · Abstract. In this talk, we will describe different variants of the NTRU problem, and study how they compare to each other (and to other more classical lattice …

However, we could only estimate the hardness of the specific parameterized NTRU problems from the perspective of actual attacks, and whether … 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.
