Abstract

In this paper, a novel quantum encryption algorithm for color image is proposed based on multiple discrete chaotic systems. The proposed quantum image encryption algorithm utilize the quantum controlled-NOT image generated by chaotic logistic map, asymmetric tent map and logistic Chebyshev map to control the XOR operation in the encryption process. Experiment results and analysis show that the proposed algorithm has high efficiency and security against differential and statistical attacks.

Summary

INTRODUCTION

QUANTUM interest for computer, mathematics, and physical scientists. It is a discipline devoted to the development of novel quantum protocols/algorithms for storing, processing, and retrieving visual information [1]. One year later, based on double random-phase encoding and generalized Arnold transform, a quantum image encryption algorithm is proposed by Zhou et al [8]. 2016, based on Chen’s hyper-chaotic system, a quantum color image encryption algorithm is proposed in Tan et al.’s work [11]. To the best of our knowledge, in the earlier works, there is no quantum image encryption algorithm based on multiple discrete chaotic systems The study of utilizing multiple discrete chaotic systems in quantum color image encryption algorithms is required. A novel quantum color image encryption algorithm is proposed based on multiple discrete chaotic maps. Based on simulations results and numerical analyses, the proposed quantum color image algorithm demonstrates the efficiency as well as security against differential and statistical attacks
