Comparing a Novel DNA N-XOR Encoding to DNA Subtractive Encoding Improves the Entropy of RGB Image Encryption.

Abstract

Aim: In this paper, the entropy of Red Green Blue image encryption using novel Deoxy Nucleic Acid N-XOR encoding is compared with DNA subtractive encoding using MATLAB software. Materials and Methods: The Image Encryption is performed using Novel DNA N-XOR encoding where number of samples (N=10) and subtractive encoding with number of samples (N=10) having pre-test power of 80% using MATLAB software. Results: The entropy of Novel DNA N-XOR encoding is 1.6206 whereas the entropy of DNA subtractive encoding is 1.5910. There is a significant difference in the results obtained for entropy and were considered to be error-free since it has the significance value p=0.0192 (p<0.5) in SPSS statistical analysis. Conclusion: Novel DNA N-XOR encoding performs significantly better in increasing entropy in RGB image encryption when compared to DNA subtractive encoding.
