Lattice-Based proof of a shuffle [PDF]

, 2019
In this paper we present the first fully post-quantum proof of a shuffle for RLWE encryption schemes. Shuffles are commonly used to construct mixing networks (mix-nets), a key element to ensure anonymity in many applications such as electronic voting ...

Machine Learning-Based Models for the Estimation of the Energy Consumption in Metal Forming Processes

Metals, 2021
This research provides an insight on the performances of machine learning (ML)-based algorithms for the estimation of the energy consumption in metal forming processes and is applied to the radial-axial ring rolling process.

A New Algorithm for Solving Ring-LPN with a Reducible Polynomial [PDF]

, 2014
The LPN (Learning Parity with Noise) problem has recently proved to be of great importance in cryptology. A special and very useful case is the RING-LPN problem, which typically provides improved efficiency in the constructed cryptographic primitive.

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 ...

Anonymous Quantum Safe Construction of Three Party Authentication and Key Agreement Protocol for Mobile Devices

IEEE Access
Once the shared secret key is established, three parties can use it for secure communication using symmetric-key encryption AES (128, 192, 256) algorithms or other cryptographic primitives.

Multi-key homomorphic encryption with tightened RGSW ciphertexts without relinearization for ciphertexts product

Journal of King Saud University: Computer and Information Sciences, 2023
Most previous RLWE-based multi-key homomorphic encryptions (MKHEs) need to perform complex relinearization operations on ciphertext products to complete the evaluation of circuits of bounded polynomial depth.

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.

Provably weak instances of ring-LWE revisited [PDF]

, 2016
In CRYPTO 2015, Elias, Lauter, Ozman and Stange described an attack on the non-dual decision version of the ring learning with errors problem (RLWE) for two special families of defining polynomials, whose construction depends on the modulus q that is ...
