In this work the definition of codes as modules over skew polynomial rings of automorphism type is generalized to skew polynomial rings, whose multiplication is defined using an automorphism and a derivation. This produces a more general class of codes which, in some cases, produce better distance bounds than module skew codes constructed only with an automorphism. Extending the approach of Gab...

Let K be a field of characteristic pi^O, to exclude trivial cases) and let G be a finite goup. A XG-module M is a finite dimensional K-vector space, on which G acts Jf-linearly from the left. The Green ring a(G) of G(w.r.t. K) is the free abelian group, spanned by the isomorphism classes of indecomposable i£G-modules, with the multiplication induced from the tensor product © x of KGmodules (see...

Securing the data stored on E-passport is a very important issue. RSA encryption algorithm is suitable for such application with low data size. In this paper the design and implementation of 1024 bit-key RSA encryption and decryption module on an FPGA is presented. The module is verified through comparing the result with that obtained from MATLAB tools. The design runs at a frequency of 36.3 MH...

Galois/Counter Mode of Operation (GCM) is a block cipher mode operation used to provide encryption and authentication using universal Hashing based on multiplication over binary Galois/Finite Field.GCM can be implemented on both hardware and software effectively and efficiently. GCM supports pipelined and parallelized implementations to have minimal computational latency in order to be useful a...

All rings are commutative with identity and all modules are unital. Let R be a ring, M an R-module and R (M), the idealization of M . Homogeneous ideals of R (M) have the form I (+)N where I is an ideal of R, N a submodule of M and IM ⊆ N . The purpose of this paper is to investigate how properties of a homogeneous ideal I (+)N of R (M) are related to those of I and N . We show that if M is a m...

We investigate interconnected aspects of hyperderivatives polynomials over finite fields, q -th powers polynomials, and specializations Vandermonde matrices. construct formulas for Carlitz multiplication coefficients using symmetric we prove identities hyperderivative power sums in terms the inverse matrix. As an application these results give a new proof theorem Thakur on explicit Anderson's s...

A Q-curve is an elliptic curve defined over Q that is isogenous to all its Galois conjugates. The term Q-curve was first used by Gross to denote a special class of elliptic curves with complex multiplication having that property, and later generalized by Ribet to denote any elliptic curve isogenous to its conjugates. In this paper we deal only with Q-curves with no complex multiplication, the c...

This research is motivated by the need to provide teaching materials in form of electronic-based modules (e-modules) integrated with numeracy literacy learning. Where math books are less able delivery related literacy. Given lack a learning process during covid 19 period improve students' abilities field numeracy. The objective develop an e-module for multiplication and division fractions grade...

let a be a banach algebra and e be a banach a-bimodule then s = a  e, the l1-direct sum of a and e becomes a module extension banach algebra when equipped with the algebras product (a; x):(a′; x′) = (aa′; a:x′ + x:a′). in this paper, we investigate △-amenability for these banach algebras and we show that for discrete inverse semigroup s with the set of idempotents es, the module extension bana...
