On the hardness of the ntru problem
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 ...

The … 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
Webfunction 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.
