Abstract: Protection of data from cyber attacks and illegal access involves the application of cryptographic methods. Using images to encrypt and hide information, visual cryptography presents a new ...

A collection of classical cryptographic algorithms implemented in C++, including Caesar Cipher, Vigenère Cipher, Playfair Cipher, and more. Ideal for learning encryption fundamentals and cryptography ...

This project implements the Caesar Cipher algorithm to encrypt and decrypt text using a shift value. The Caesar Cipher is one of the simplest and most widely known encryption techniques in ...

Diffie-Hellman’s key-exchange method runs this kind of exponentiation protocol, with all the operations conducted in this way ...

In cryptography, a Caesar Cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter ...

Abstract: S-boxes are the only nonlinear component in most cryptographic algorithms, which determine the security strength of the whole symmetric ciphers algorithm. In this work we utilize a ...
