A few weeks back, I kicked off a public build challenge: constructing a blockchain from absolute zero, in Go, one layer at a time. We started at the very bottom, with finite fields. It's the ...

Abstract: The substitution box (S-box) component is the heart of the advanced encryption standard (AES) algorithm. The S-box values are generated from the multiplicative inverse of Galois finite field ...

Abstract: This paper presents a procedure for calculating multiplicative inverses Modulo 2 m, based on a novel mathematical approach. The procedure is suitable for software implementation on a general ...

Given the large volumes of sensitive information transmitted over the Internet, digital signatures are essential for verifying message authenticity and integrity. A key challenge is minimizing ...

A basic feature of number theory, prime numbers are also a fundamental building block of computer science, from hashtables to cryptography. Everyone knows that a prime number is one that cannot be ...

In Java, classes and objects are the building blocks of object-oriented programming. A class is a template or blueprint that defines a set of attributes and behaviors for objects of that class. An ...

This is a pure Java implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA). It is compatible with Java 8+ and OpenSSL. It uses elegant math such as Jacobian Coordinates to speed up ...

This is a basic Java Swing application to implement the most commonly used computations in elliptic curve cryptography. It is intended to be used for instructive purposes (by students or educators) ...

New software optimizes kinematics and plans paths for custom robots handling multiple axes. Flexible Robotic Environment (FRE) software was written by Bicommerce LLC, Rapid City, S. D., and it also ...

ABSTRACT: Numerous cryptographic algorithms (ElGamal, Rabin, RSA, NTRU etc) require multiple computations of modulo multiplicative inverses. This paper describes and validates a new algorithm, called ...
