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.
