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. 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.
