The Ring Learning With Errors Problem: Spectral Distortion
, 2020 We answer a question posed by Y. Elias et al. in [8] about possible spectral distortions of algebraic numbers. We provide a closed form for the spectral distortion of certain classes of cyclotomic polynomials. Moreover, we present a bound on the spectral distortion of cyclotomic polynomials.

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

The Ring-LWE Problem in Lattice-Based Cryptography: The Case of Twisted Embeddings
Entropy, 2021 Several works have characterized weak instances of the Ring-LWE problem by exploring vulnerabilities arising from the use of algebraic structures. Although these weak instances are not addressed by worst-case hardness theorems, enabling other ring ...

Fast Number Theoretic Transform for Ring-LWE on 8-bit AVR Embedded Processor
Sensors, 2020 In this paper, we optimized Number Theoretic Transform (NTT) and random sampling operations on low-end 8-bit AVR microcontrollers. We focused on the optimized modular multiplication with secure countermeasure (i.e., constant timing), which ensures high ...

Lattice-Based Group Signature with Message Recovery for Federal Learning
Applied Sciences, 2023 Federal learning and privacy protection are inseparable. The participants in federated learning need to be the targets of privacy protection. On the other hand, federated learning can also be used as a tool for privacy attacks.

Estimating the Security of Ring Learning with Errors (RLWE)
, 2022 This article was written by my colleague, Cathie Yun. Cathie is an applied cryptographer and security engineer, currently working with me to make fully homomorphic encryption a reality at Google. She's also done a lot of cool stuff with zero knowledge proofs.

Shorter Linkable Ring Signature Based on Middle-Product Learning with Errors Problem
The Computer Journal, 2022 Abstract DualRing is a novel generic construction introduced by Yuen et al. (CRYPTO’21), which can transform a special kind of (Type-T*) canonical identification scheme to a ring signature scheme. Compared with the classical approaches, this method can get a shorter signature.
