Cao Minh Thang, Nguyen Binh

Open publisher page 7 citations

Abstract

NTRU is a probabilistic public key cryptosystem having security related to some hard problems in lattices. The original NTRU operates on the on a N-ft degree truncated polynomial ring R = Z[x]/(xn+ 1). In this paper, DBTRU, a new variant of NTRU based on two binary truncated polynomial rings GF(2)[x]/(xn+ 1)|n ϵ Z+is proposed along with some security and performance advantages in comparison with standard NTRU.
