Abstract: In this paper, we have proposed an encryption method which is developed by extending Playfair Cipher to make it more secure. Known as Polyalphabetic cipher, Playfair uses a key matrix ...
Abstract: As digital communication grows, protecting transmitted images, especially in wireless communication, is more important. This paper introduces an image encryption method that combines the ...
A modern web application for encrypting and decrypting messages using the Playfair cipher algorithm. Features a clean, professional UI built with HTML, CSS, and JavaScript, backed by a Java HTTP ...
A cryptographically secure implementation of the Vernam Cipher (one-time pad) using the Blum-Blum-Shub (BBS) pseudorandom number generator for key generation. This project demonstrates a practical ...
