In 2012, Ding et al. published the first key exchange system based on LWE problem that is provably secure [9]. It can be easily proven that the security of NTRU depends on the difficulty to solve the SVP in NTRU lattice.

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. dainty rings silverWebform over its domain.
