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.

However, from a reduc-tion perspective, its relative hardness … 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.

More precisely, we will show that one of the search variant of the NTRU problem is at least as hard as the shortest vector problem (SVP) in ideal lattices; and that ... greatest college basketball coach of all timeWebfunction was proven collision-resistant under the assumed hardness of the modi-fied average-case problem, called Ideal-SIS. The latter was itself proven at least as hard as the restrictions of standard worst-case lattice problems to a specific class of lattices (called ideal lattices). In 2009, Stehlé et al.
