INSPIRED PSEUDO BIOTIC DNA BASED CRYPTOGRAPHIC MECHANISM AGAINST ADAPTIVE CRYPTOGRAPHIC ATTACKS

摘要

DNA Cryptography is a new cryptographic paradigm from hastily growing bio molecular computation, as its computational power will determine next generation computing. As technology is growing much faster, data protection is getting more important and it is necessary to design the unbreakable encryption technology to protect the information. In this paper, we proposed a biotic DNA based secret key cryptographic mechanism, seeing as DNA computing had made great strides in ultra-compact information storage, vast parallelism, and exceptional energy efficiency. This Biotic Pseudo DNA cryptography method is based upon the genetic information on biological systems. This method makes use of splicing system to improve security, random multiple key sequence to increase the degree of diffusion and confusion which makes resulting cipher texts difficult to decipher and makes to realize a perfect secrecy system. The formal and experimental analysis not only shows that this method is powerful against brute force attack and chosen cipher text attacks, but also it is very efficient in storage, computation as well as transmission.
