ICIGA: Improved Cryptography Inspired by Genetic Algorithms

Abstract

This work is a contribution to cryptography. We have developed a symmetrical blocks ciphering system, that is an improvement of our cryptosystem inspired from genetic algorithm published in AMSE periodical. His complexity is o(n) because all operations used are simple and they are applied randomly in ciphering. Furthermore, in our system the user can choose the size blocks and the length key
