Kyber, Saber, and SK‐MLWR Lattice‐Based Key Encapsulation Mechanisms Model Checking with Maude
IET Information Security, Volume 2023, Issue 1, 2023., 2023 Facing the potential threat raised by quantum computing, a great deal of research from many groups and industrial giants has gone into building public‐key post‐quantum cryptographic primitives that are resistant to the quantum attackers. Among them, there is a large number of post‐quantum key encapsulation mechanisms (KEMs), whose purpose is to provide

Improved lattice enumeration algorithms by primal and dual reordering methods
IET Information Security, Volume 17, Issue 1, Page 35-45, January 2023., 2023 Abstract The security of lattice‐based cryptosystems is generally based on the hardness of the Shortest Vector Problem (SVP). The original enumeration (ENUM) algorithm solving SVP runs in exponential time due to the exhaustive search, which is used as a subroutine for the block Korkin–Zolotarev (BKZ) algorithm.

LaTLS: A Lattice‐Based TLS Proxy Protocol
Chinese Journal of Electronics, Volume 31, Issue 2, Page 313-321, March 2022., 2022 The function of the Internet proxy is to check and convert the data exchanged between client and server. In fact, the two‐party secure communication protocol with good security is turned into an unsafe multiparty protocol. At present, there are relatively few proxy protocols that can be applied in practice.

Lattice‐based hash‐and‐sign signatures using approximate trapdoor, revisited
IET Information Security, Volume 16, Issue 1, Page 41-50, January 2022., 2022 Abstract For the purpose of improving the efficiency of the cryptosystems built upon lattice trapdoors, Chen, Genise and Mukherjee at ASIACRYPT 2019 modified the gadget trapdoor (G‐trapdoor) to an approximate trapdoor, which enables one to sample short preimages approximately from a discrete Gaussian distribution.

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Forward‐secure revocation is a powerful cryptographic technique to alleviate key exposure attacks on identity‐based cryptosystems. In recent years, quantum computers have made some breakthroughs, so in the foreseeable future, existing cryptographic systems will be subject to quantum attacks.

A New Attack on NTRU Public Key Cryptosystem Depend on Using Public Key and Public Information [PDF]
Engineering and Technology Journal, 2010 This paper proposed a new method to attack the NTRU cryptosystem [Hof00a,Hof98b]. It tried to exploit the public information about the parameters of NTRUcryptosystem and using the public key, to recover the private keys without delvingin the detail of ...

Generalisations of NTRU cryptosystem
Security and Communication Networks, 2016 AbstractSince the proposal of NTRU cryptosystem, many variants were proposed by the researcher using different‐different algebraic structure. In this article, we try to explore the existing variants of NTRU cryptosystem with their comparative study. Copyright © 2016 John Wiley & Sons, Ltd.

MaTRU: A New NTRU-Based Cryptosystem [PDF]
, 2005 In this paper, we propose a new variant of the NTRU public key cryptosystem – the MaTRU cryptosystem. MaTRU works under the same general principles as the NTRU cryptosystem, except that it operates in a different ring with a different linear transformation for encryption and decryption.
