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. Webcryptosystem of McEliece [22]. The security of GGH is related to the hardness of ap-proximating the closest vector problem (CVP) in a lattice. The GGH article [9] focused on encryption, and ﬁve encryption challenges were issued on the Internet [10]. Two years later, Nguyen [29] found a ﬂaw in the original GGH encryption scheme, which al-

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. WebThe hardness of the NTRU and Ring-LWE problem directly depends on the degree of the polynomial f(X). Based on the current state of knowledge, obtaining 128-256 bit hardness requires taking dimensions somewhere between 512 and 1024.
