The security of this digital signature is based on the assumptions about hardness of Ring-LWE and Ring-SIS problems, along with providing public key and signature of Webform over its domain. The security then follows from the already proven hardness of the Ideal-SIS and R-LWE problems. Keywords.

"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.

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.
