Abstract
In recent days, DNA cryptography is gaining more popularity for providing better security to image and text data. This paper presents a DNA based cryptographic solution for image and textual information. Image encryption involves scrambling at pixel and bit levels based on hyperchaotic sequences. Both image and text encryption involves basic DNA encoding rules, key combination, and conversion of data into binary and other forms. This new DNA cryptographic approach adds more dynamicity and randomness, making the cipher and keys harder to break. The proposed image encryption technique presents better results for various parameters, like Image Histogram, Correlation co-efficient, Information Entropy, Number of Pixels Change Rate (NPCR), and Unified Average Changing Intensity (UACI), Key Space, and Sensitivity compared with existing approaches. Improved time and space complexity, random key generation for text encryption prove that DNA cryptography can be a better security solution for new applications.
Highlights
Security is often a crucial necessity for sensitive data transmission over communication networks
Image Encryption plays a vital role in secured multimedia communication but the existing symmetric and asymmetric algorithms suffer from side-channel attack, Brute Force attack, Differential attack, and other statistical attacks [4]
The analysis of various parameters like Image Histogram, Correlation coefficient, Information Entropy, Number of Pixels Change Rate (NPCR), and Unified Average Changing Intensity (UACI), Key Space, and Sensitivity shows that the proposed technique overcomes the limitations of the existing image encryption techniques
