Integrating DNA Computing in International Data Encryption Algorithm 'IDEA'

Abstract

DNA cryptography is a field which is being explored worldwide and even in being in its primitive stages it has revolutionized the area of network security. Here we are applying DNA computing on well known IDEA algorithm for making it more secure. We are adding a layer of DNA cipher over the basic IDEA algorithm. The cipher now will be in form of DNA sequence which will even hide very existence of the underlying IDEA algorithm. Key space has been extended a bit to make it more immune to cryptanalytic attacks. It can transmit highly confidential data efficiently and securely. The Matlab has been used for implementation.
