Efficient Lattice-Based Ring Signature Scheme without Trapdoors for Machine Learning. [PDF]
Comput Intell Neurosci, 2022 Machine learning (ML) and privacy protection are inseparable. On the one hand, ML can be the target of privacy protection; on the other hand, it can also be used as an attack tool for privacy protection. Ring signature (RS) is an effective way for privacy protection in cryptography. In particular, lattice‐based RS can still protect the privacy of users

NTRU-type fully homomorphic encryption scheme without key switching
网络与信息安全学报, 2017 In order to construct a fully homomorphic encryption scheme based on NTRU cryptosystem from ring learning with errors, noise growth and homomorphic property in the NTRU cryptosystem were analyzed. The con-cept of zero homomorphic encryption was introdced

CQTRU: A Commutative Quaternions Rings Based Public Key Cryptosystem [PDF]
Engineering and Technology Journal, 2016 In this paper, we propose a new version of the NTRU public key cryptosystem called CQTRU. It is a four-dimensional cryptosystem based on the commutative quaternion ring.

Lattice Attacks on NTRU Revisited
IEEE Access, 2021 NTRU cryptosystem was proposed by J. Hoffstein, J.Pipher and J.H. Silverman in 1996, whose security is related to the hardness of finding sufficient short vectors in NTRU lattice with dimension $2N$ .

Security Analysis of Hybrid Attack for NTRU-Class Encryption Schemes
IEEE Access, 2023 One of the significant post-quantum cryptographic candidates is the NTRU public key cryptosystem. It operates on polynomial rings, where the parameter largely determines the security of the system.

Quantum algorithms for attacking hardness assumptions in classical and post‐quantum cryptography
IET Information Security, Volume 17, Issue 2, Page 171-209, March 2023., 2023 Abstract In this survey, the authors review the main quantum algorithms for solving the computational problems that serve as hardness assumptions for cryptosystem. To this end, the authors consider both the currently most widely used classically secure cryptosystems, and the most promising candidates for post‐quantum secure cryptosystems.

Lattice‐based cryptosystems in standardisation processes: A survey
IET Information Security, Volume 17, Issue 2, Page 227-243, March 2023., 2023 Abstract The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives. Due to solid security and desirable performance, lattice‐based cryptosystems are viewed as promising candidates in the upcoming ...

Transactions on Cryptographic Hardware and Embedded Systems, 2023 The main protection against side-channel attacks consists in computing every function with multiple shares via the masking countermeasure. While the masking countermeasure was originally developed for securing block-ciphers such as AES, the protection ...

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

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.
