Colour Image Encryption Using DNA Coding and Logistic Diffusion

The necessity to meet the security demands of digital images has led to effective encryption methods. The suggested encryption technique combines image encryption utilizing chaotic transforms and DNA (Deoxyribonucleic acid) coding procedures. DNA computing techniques are 100 times faster and have less power consumption than other algorithms in modern computers. Using a suitable chaotic map, the encryption technique is done separately on the color image's R, G, and B channels. After chaotic encryption, a technique called DNA encoding is used. A novel conditional shift based on Mandelbrot Set is presented to apply confusion to the three channels successfully. The suggested encryption method, according to security analysis, performs admirably in terms of security.
