ABSTRACT

This paper introduces a new concept of the generation of a unending pool of keys through an image leaving behind the idea of sending keys every time for encryption and decryption. This can help in avoiding the problem of frequent key exchanges and the after affects associated with it. In this a single image is used to generate the various keys. Thus say ,if the image is of 2n bytes, taking n from 0 to any valid integer value gives a big pool of keys making it useful for any symmetric encryption technique, DES, AES, RC4, CAST, twofish, blowfish etc. This adds the advantage of one time usage of key and avoids the disadvantage of securing and sending it on the network.
