D-GIFT: Cryptography Algorithm Development Using Dynamic DNA and A Chaos Map

Abstract

Recently, the growth of data transmission through various networks has the necessity for an elevated level of security. Encryption is one of the essential technologies for protecting and ensuring the integrity of IoT devices. Secure communication among constrained devices is critical during data transmission from the client to the server devices. Lightweight cipher algorithms are defined as a secure solution for devices with limited computational functions and memory. On the other hand, most lightweight algorithms suffer from a trade-off between complexity and speed to produce a robust cipher algorithm. This paper evaluates the effectiveness of an image encryption technique that uses a Lightweight GIFT algorithm and logistic map equation-based dynamic DNA coding to create a secure, lightweight cipher algorithm for IoT devices. When we employed dynamic DNA coding by the binary bit method, we observed that the developed approach is more secure and has a high level of randomness due to the results. Additionally, the correlation between nearby pixels is approximately zero; there is no association between the two images. Therefore, the developed approach achieves a higher encryption efficiency when compared to the original algorithm.
