On the hardness of the ntru problem
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. Web5 de abr. de 2024 · English Page; 立教大学HPへ; 研究者情報トップページへ

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 ... 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
