S-DAC: A Novel Dynamic Substitution boxes using hybrid chaotic system and Deoxyribonuceic Acid(DNA) coding for counterfeiting Side-Channel Attacks.

With the advent of the Internet of Things (IoT), security methods need improvisation to prevent data stealing. Since IoT transfers the various heterogeneous data such as video, text, data signals, and even voices, efficient security systems must overcome the various attacks in the networks. IoT is often connected with low power devices, and these devices are vulnerable to attacks as it contains low security. Therefore, this requires a robust encryption method to protect the user data from the attacker. Traditional methods such as Data Encryption Systems (DES) and Advanced Encryption Systems (AES) are playing an essential role in ensuring the security in IoT devices, and the presence of substitution boxes (S-boxes) makes the system even more complex to counterfeit the attacks mainly side-channel attacks. Researchers claim that these traditional S-boxes need to be improvised when transmitting heterogeneous data, especially the images over the network. In this paper, A Novel dynamic substitution boxes are designed based on hybrid logistic-Henon maps with the deoxyribonucleic acid (DNA) coding systems to improve the security level of images against the side-channel attacks. The proposed structure uses the three-dimensional hybrid chaotic maps to increase the key space and uses the DNA pattern of operations to endure more security. The extensive experimentations are carried out for the proposed scheme and compared with the existing AES S-box structures. Analysis shows that the proposed structure is more resistant against side-channel attacks, as alleged. [ABSTRACT FROM AUTHOR]
