Abstract

This paper presents a Quantum encryption technique which is built by adopting Haar Integer Wavelet Transform (HIWT), RC6 (Rivest Cipher) block cipher and DNA (deoxyribonucleic acid) sequences. A Unified Chaotic Logistic Tent Map (ULTM) has been employed in the permutation phase to produce the pseudo-random sequence for shuffling the RGB planes of the Quantum represented source image in spatial and transform domains. HIWT is adapted to extract various subband information from the Quantum represented source image. Then RC6 block cipher encryption is used to encrypt LL subband which contains an informative part of an image. Further, it is encoded based on the DNA sequence order and performed DNA-XNOR operation. The proposed encryption algorithm is implemented using Novel Enhanced Quantum Image Representation (NEQR) on various test images with statistical and differential attack analyses. This technique yields average entropy of 7.992, correlations of horizontal -0.000043, vertical 0.00002, diagonal -0.02204 and a larger keyspace of 10204 respectively. By various analyses, it has confirmed the significant immune level of the Quantum cryptosystem.
