The Ring-LWE Problem in Lattice-Based Cryptography: The Case of Twisted Embeddings [PDF]
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 ...

How to Construct Polar Codes for Ring-LWE-Based Public Key Encryption [PDF]
Entropy, 2021 There exists a natural trade-off in public key encryption (PKE) schemes based on ring learning with errors (RLWE), namely: we would like a wider error distribution to increase the security, but it comes at the cost of an increased decryption failure rate

Fast Number Theoretic Transform for Ring-LWE on 8-bit AVR Embedded Processor [PDF]
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 ...

A Ring-LWE-based digital signature inspired by Lindner–Peikert scheme
Journal of Mathematical Cryptology, 2022 In this article, we give a digital signature by using Lindner–Peikert cryptosystem. The security of this digital signature is based on the assumptions about hardness of Ring-LWE and Ring-SIS problems, along with providing public key and signature of ...

(In)Security of Ring-LWE Under Partial Key Exposure
Journal of Mathematical Cryptology, 2020 We initiate the study of partial key exposure in Ring-LWE (RLWE)-based cryptosystems. Specifically, we (1) Introduce the search and decision Leaky R-LWE assumptions (Leaky R-SLWE, Leaky R-DLWE), to formalize the hardness of search/decision RLWE under ...

An MLWE-Based Cut-and-Choose Oblivious Transfer Protocol [PDF]
EntropyThe existing lattice-based cut-and-choose oblivious transfer protocol is constructed based on the learning-with-errors (LWE) problem, which generally has the problem of inefficiency.

CHIMERA: Combining Ring-LWE-based Fully Homomorphic Encryption Schemes
Journal of Mathematical Cryptology, 2020 This paper proposes a practical hybrid solution for combining and switching between three popular Ring-LWE-based FHE schemes: TFHE, B/FV and HEAAN. This is achieved by first mapping the different plaintext spaces to a common algebraic structure and then ...

Characterizing Disease Severity Through Surgical Recurrence Rates in Idiopathic Subglottic Stenosis. [PDF]
LaryngoscopeThe following investigation examined endoscopic surgical interval rates across a patient with idiopathic subglottic stenosis (iSGS) first 2 years of treatment compared to their last 3 years of treatment over a total of 5 years of follow up. Through comparison of these two intervals a disease severity classification for iSGS based on decreasing ...
