COMPUTATIONAL SCIENCE GUIDED SOFT COMPUTING BASED CRYPTOGRAPHIC TECHNIQUE USING ANT COLONY INTELLIGENCE FOR WIRELESS COMMUNICATION (ACICT)

In this paper, a computational science guided soft computing based cryptographic technique using Ant Colony Intelligence (ACICT) has been proposed. In this proposed approach at first a metamorphosed based strategy is used to produce intermediate cipher text. Finally, ACI generated keystream is used to further encrypt the intermediate cipher text to produce the final cipher text. In this approach an ant agent having a pheromone deposition consisting of a group of alphanumeric characters is called a key stream and each character in the key stream is known as key. The key stream length always be less than or equal to the plaintext to be encrypt. The keystream generation is based on distribution of characters in the plaintext. Instead of transmitting the plain keystream to the receiver, further encryption is done on keystream and encrypted keystream get transmitted to the receiver. Parametric tests are done and results are compared with some existing classical techniques, which show comparable results for the proposed system
