Abstract
Several encryption techniques based on DNA encoding have been presented in recent years for color image encryption. Image encryption is one of the most significant fields of study that has piqued the worldwide attention of scholars, and it is relevant in transferring important images via communication channels, that are insecure. In this paper, a review of color image encryption algorithms based on DNA coding is conducted from 2015 to 2021. The comparison findings on 12 included experiments in relation to correlation coefficient, key space, information entropy, NPCR, and UACI revealed that the encryption methods improved significantly. In conclusion, the DNA-based image encryption approaches offer a superior trade-off between security and computational complexity, and have been highlighted as an essential component in the construction of a trustworthy and authenticated cryptosystem.
