Image Data Protection Using a Novel 2D-HIM and DNA Based Encryption
2026
Overview
The advancement in digital communication poses a risk to the confidentiality of every individual. To protect information, chaos-based encryption is being exploited in recent research. The complexity of the algorithm is yielded by introducing a hyperchaotic map. This paper proposes a novel Two-Dimensional Henon Ikeda Map (2D-HIM) by combining the Henon map and the Ikeda map. The pseudo-random sequence is generated by the novel 2D-HIM applied to the DNA-based image encryption algorithm. This algorithm ensures the scrambling of pixels into an encrypted form that is unrecognisable. The cryptosystem has been analysed on various colour images, obtaining nearly an NPCR of 99.75%, a UACI of 33.84%, and an entropy of 7.99. Thus, the proposed algorithm ensures resistance against various statistical attacks and differential attacks, implying a robust solution to confidentiality in open communication and suitability for use in cryptographic applications.
