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 ... WebThe shortest vector problem (SVP) is that of de-termining the shortest non-zero vector in L. Hermite’s theorem suggests that in a \random" lattice, min kvk: 0 6=v 2L p nDisc(L)1=n: The closest vector problem (CVP) is that of de-termining the vector in Lthat is closest to a given non-lattice vector w.
