Key based bit level genetic cryptographic technique (KBGCT)

This is an encryption and decryption algorithm with the help of genetic functions cryptography. This new algorithm is developed for encryption and decryption process. This algorithm combines the features of Genetic Algorithm in Cryptography. Here we generate random numbers for “Crossover” and “Mutation”. The encryption and decryption algorithms will be made public. The algorithm contains a key, which is known to only sender and receiver. In this technique the input file is broken down into different blocks of various sizes. The main algorithm works in two stages. Bit Level XOR operation followed by Genetic Crossover and Mutation.
