Several ideal-lattice-based cryptosystems have been broken by recent attacks that exploit
special structures of the rings used in those cryptosystems. The same structures are also …

Over the last years lattice-based cryptography has received much attention due to versatile
average-case problems like Ring-LWE or Ring-SIS that appear to be intractable by quantum …

In the emerging Internet of Things, lightweight public-key cryptography is an essential
component for many cost-efficient security solutions. Since conventional public-key …

With the rapid increase in demand for data trustworthiness and data security, distributed
data storage technology represented by blockchain has received unprecedented attention …

In recent years, lattice-based cryptography has attracted a high degree of attention in the
cryptologic research community. It is expected to be in wide use in the foreseeable future …

Recently in two independent papers, Albrecht, Bai and Ducas and Cheon, Jeong and Lee
presented two very similar attacks, that allow to break NTRU with larger parameters and …

NTRU is a fast public key cryptosystem remaining unbroken. However, there is no known
worst-to-average reduction for the original NTRU cryptosystem. Several provably secure …

NTRUEncrypt is generally recognized as one of candidate encryption schemes for post
quantum cryptography, due to its moderate key sizes, remarkable performance and potential …

Leveled authentication allows resource-constrained IoT devices to be authenticated at
different strength levels according to the particular types of communication. To achieve …

NTRUEncrypt is a fast and standardized lattice-based public key encryption scheme, but it
lacks a proof of security. Stehle and Steinfeld (EUROCRYPT 2011) first gave a variant of …
