On the hardness of the ntru problem

Webanalyzing the ‘statistical region’ NTRU key cracking problem in Section 4.3, and then in Section 4.4 briefly look at how the NTRU ciphertext cracking problem relates to the now well-known Ring-LWE problem and worst-case lattice problems. Moving to recent novel applications of NTRU in Section 5, in Section 5.1 we review the ho- Webform over its domain. The security then follows from the already proven hardness of the Ideal-SIS and R-LWE problems. Keywords. Lattice-based cryptograph,y NTRU, ideal lattices, proablev securit.y 1 Introduction The NTRU encryption scheme devised by Ho stein, Pipher and Silverman, was rst presented at the rump session of Crypto'96 [16].

In this paper, we construct Fiat-Shamir signatures based on variant Module-NTRU lattices. Further generalizing Module-NTRU, we introduce the inhomogeneous … 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.
