Suitability of Generalized GAROs on FPGAs as PUFs or TRNGs Considering Spatial Correlations

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2023
In the last years, guaranteeing the security in Internet of things communications has become an essential task. In this article, the bias of a wide set of oscillators has been studied to determine their suitability as both true random number generators ...

Projections of Galois Rings

open access: yesAlgebra and Logic, 2015
Let R and R (phi) be associative rings with isomorphic subring lattices and phi be a lattice isomorphism (a projection) of the ring R onto the ring R (phi) . We call R (phi) the projective image of a ring R and call the ring R itself the projective preimage of a ring R (phi) . We study lattice isomorphisms of Galois rings.

On the Galois Theory of Division Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1959
1. Throughout this paper, K will represent a division ring and L a galois division subring. We are interested in establishing a galois theory for the extension K/L when K/L is locally finite. In order to do this one must identify the galois subrings of K containing L. An example given by Jacobson [4] shows that not every such division subring is galois.

The general Ikehata theorem for H-separable crossed products

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Let B be a ring with 1,   C the center of B,   G an automorphism group of B of order n for some integer n,   CG the set of elements in C fixed under G,   Δ=Δ(B,G,f) a crossed product over B where f is a factor set from G×G to U(CG). It is shown that Δ is

Calculation of Fourier-Galois transforms in reduced binary number systems [PDF]

open access: yesКомпьютерная оптика, 2018
The paper proposes a new method for calculating Fourier-Galois transforms (number-theoretical transforms), which are a modular analog of the discrete Fourier transform.

Finite completely primary rings in which the product of any two zero divisors of a ring is in its coefficient subring

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
According to general terminology, a ring R is completely primary if its set of zero divisors J forms an ideal. Let R be a finite completely primary ring. It is easy to establish that J is the unique maximal ideal of R and R has a coefficient subring S (i.

Interactive Proofs for Rounding Arithmetic

open access: yesIEEE Access, 2022
Interactive proofs are a type of verifiable computing that secures the integrity of computations. The need is increasing as more computations are outsourced to untrusted parties, e.g., cloud computing platforms.

On Azumaya algebras with a finite automorphism group

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Let B be a ring with 1, C the center of B, and G a finite automorphism group of B. It is shown that if B is an Azumaya algebra such that B=⊕∑g∈GJg where Jg={b∈B|bx=g(x)b   for all   x∈B}, then there exist orthogonal central idempotents {fi∈C|i=1,2,…,m ...

ON THE IRREDUCIBLE COMPONENTS OF SOME CRYSTALLINE DEFORMATION RINGS

open access: yesForum of Mathematics, Sigma, 2020
We adapt a technique of Kisin to construct and study crystalline deformation rings of $G_{K}$ for a finite extension $K/\mathbb{Q}_{p}$. This is done by considering a moduli space of Breuil–Kisin modules, satisfying an additional Galois condition, over ...

Polynomial composites and certain types of fields extensions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2023
In this paper, we consider polynomial composites with the coefficients from $K\subset L$. We already know many properties, but we do not know the answer to the question of whether there is a relationship between composites and field extensions.
