Abstract
DNA cryptography is an exciting development in the growing area of DNA computing. Computing at the molecular level, such as that found in DNA, is known as bio-molecular computing. DNA is not just a data storage medium, but also a computational instrument. Researchers have placed a premium on DNA Computation because to its unique ability to store vast quantities of information. Traditional crypto algorithms have been shown to be flawed. Better information security may be achieved by integrating the fields of biology, chemistry, and computer science into a single, cohesive field of study. In this paper, we present a model that take image as a key and encrypts data by making use of DNA codons. Using a different key created by a key generation method in each cycle is a defining feature of the proposed technique, making it almost difficult to decrypt the picture using a cryptanalytic assault. It is also shown that the suggested method outperforms several preexisting algorithms when assessed by an avalanche effect.
