Colour Image Encryption Using Chaotic Trigonometric Map and DNA Coding

The problem of information privacy has grown more significant in terms of data storage and communication in the 21st century due to the technological explosion during which information has become a highly important strategic resource. The idea of employing DNA cryptography has been highlighted as a potential technology that offers fresh hope for unbreakable algorithms since standard cryptosystems are becoming susceptible to assaults. Due to biological DNA's outstanding energy efficiency, enormous storage capacity, and extensive parallelism, a new branch of cryptography based on DNA computing is developing. There is still more study to be done since this discipline is still in its infancy. This work proposes a DNA encryption strategy based on cryptographic key generation techniques and chaotic diffusion operation.
