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

open access: yesEntropy, 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 ...

On the Plus Parts of the Class Numbers of Cyclotomic Fields

open access: yesChinese Annals of Mathematics Series B
We exhibit some new families of cyclotomic fields which have non-trivial plus parts of their class numbers. We also prove the $3$ - divisibility of the plus part of the class number of another family consisting of infinitely many cyclotomic fields. At the end, we provide some numerical examples supporting our results.

Cyclotomic Function Fields with Ideal Class Number One

open access: yesJournal of Algebra, 2001
A congruence function field is a function field whose field of constants is the finite field of \(q\) elements \(\mathbb{F}_q\). A congruence function field \(K/\mathbb{F}_q\) is an imaginary quadratic extension of \(\mathbb{F}_q(x)\) if \(K/\mathbb{F}_q(x)\) is a quadratic separable extension of non-zero genus such that the infinite prime are ramified.

On Some New Almost Difference Sets Constructed from Cyclotomic Classes of Order 12

open access: yesRecoletos Multidisciplinary Research Journal, 2023
Almost Difference Sets have extensive applications in coding theory and cryptography. In this study, we introduce new constructions of Almost Difference Sets derived from cyclotomic classes of order 12 in the finite field GF(q), where q is a prime ...
