Abstract

Abstract : Nanotechnology has provided immense increment in computational power. This high computational strength is very dangerous for existing cryptographic protocols and DES (Data Encryption Standard) is a classic example for that. So it is the urgent requirement that we develop new protocols or mathematical methods for data security which can remain secure from fast modern computers powered by nanotechnology. We consider the example of military communication as data communication security in military communication is a matter of national security. We present a new method for message exchange for military communication which has never been presented till now. This novelty creates a hard task for intruders and we use steganography as a supporting tool for cryptography. Security of encrypted data increases when it is hidden in a carrier file. Nobody knows (except sender and intended receiver) that there is some hidden data. We want to compare different algorithms for size restrictions because size is an important factor for steganogram and that's the only chance of guessing that the open file contains something suspicious (hidden encrypted data).
