On the hardness of ntru problems

WebNTRU problem is equivalent to finding a short vector in the NTRU lattice, which has been conjectured to be a hard problem. The hardness lies with the fact that if we take two random small polynomials , then is indistinguishable from random in . The NTRU problem is investigated from the early time of NTRU cryptosystem and is well studied in [42 ... Web1 de jan. de 2024 · Although very few theoretical hardness results are known for \textrm {NTRU}, it has been widely studied for more than two decades from a cryptanalytic standpoint. Unless for overstretched parameter sets, e.g. [ 15 ], it is believed to be a reliable hardness assumption to design public-key cryptosystems, e.g., [ 2, 11 ].

Both the signature and the verification are … WebLattice Attacks on NTRU Revisited. NTRU cryptosystem was proposed by J. Hoffstein, J.Pipher and J.H. Silverman in 1996, whose security is related to the hardness of finding sufficient short vectors in NTRU lattice with dimension 2N. Many researchers conjecture that the private key vector is indeed the shortest vector in the lattice in most cases. 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. focal power bird

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.
