NTRU+: Compact Construction of NTRU Using Simple Encoding Method [PDF]
NTRU was the first practical public key encryption scheme constructed on a lattice over a polynomial-based ring and has been considered secure against significant cryptanalytic attacks over the past few decades. However, NTRU and its variants suffer from

In this work, we propose generic and novel side-channel assisted chosen-ciphertext attacks on NTRU-based key encapsulation mechanisms (KEMs). These KEMs are IND-CCA secure, that is, they are secure in the chosen-ciphertext model.

NTRU Public Key Cryptography [PDF]
本论文主要研究NTRU(NumberTheoryResearchUnit)公钥密码系统的数学基础、分析与实现、安全与攻击、以及应用于数字签名和PKI。NTRU公钥密码算法主要研究的对象是对多项式进行加、减、乘、模等运算。用NTRU产生密钥的方法比较容易,加密、解密的速度比RSA等著名公钥算法快得多。其算法的安全性主要取决于从一个非常大的维数格中寻找最短向量的困难性。可以用格基约减的方法对NTRU算法进行倒退攻击,为了提高安全性,要精心选取NTRU算法参数。从安全性和有效性方面分析 ...

NTRU over the Eisenstein Integers
NTRU is a fast public-key cryptosystem that is constructed using polynomial rings with integer coefficients. We present ETRU, an NTRU-like cryptosystem based on the Eisenstein integers.

NTRU算法是一个新的公钥密码算法,其安全性取决于从一个非常大的维数格中寻找最短向量的困难性.作者研究了NTRU算法的安全性,使用格约化方法对NTRU算法进行攻击.并找到了一类特殊的格,由于利用了NTRU私钥的特殊结构,该格的维(dimension)比常用的格更小.研究表明,具有某种特征的NTRU密钥特别容易被攻击,但是本文的方法可以用于攻击所有的NTRU密钥.该研究不会影响NTRU的应用,只是对NTRU格参数的选取有了更加严格的限制条件.从安全性和有效性综合考虑,NTRU公钥密码体制有着广阔的应用前景.

On estimating the lattice security of NTRU
. This report explicitly refutes the analysis behind a recent claim that NTRUEncrypt has a bit security of at most 74 bits. We also sum up some existing literature on NTRU and lattices, in order to help explain what should and what should not be classed ...

LDPC Strikes Again : New Key-Recovery Chosen-Ciphertext Side-Channel Attacks on NTRU-based KEMs
In this work, we introduce novel techniques for adapting the SCA-LDPC framework to conduct efficient plaintext-checking (PC) oracle-based side-channel attacks on NTRU-style Key Encapsulation Mechanisms (KEMs). We specifically address the unique algebraic

Generalized NTRU Algorithms on Algebraic Rings
The NTRU (Number Theory Research Unit) is a prominent post-quantum public key cryptography algorithm and a current focus of research. Although many NTRU variants have been proposed, a comprehensive generalization of these variants is still lacking.
