Abstract
Color image encryption has enticed a lot of attention in recent years. Many authors proposed a chaotic system-based encryption algorithms for that purpose. However, due to the shortcomings of the low dimensional chaotic systems, similar rule structure for RGB channels, and the small keyspace, many of those were cryptanalyzed by chosen-plaintext or other well-known attacks. A Security vulnerability exists because of the same method being applied over the RGB channels. This paper aims to introduce a new three-channel three rules (3C3R) image encryption algorithm along with two novel mathematical models for DNA rule generator and bit inversion. A different rule structure was applied in the different RGB-channels. In the R-channel, a novel Block-based Bit Inversion (BBI) is introduced, in the G-channel Von-Neumann (VN) and Rotated Von-Neumann (RVN)- based 2D-cellular structure is applied. In the B-channel, a novel bidirectional State Machine-based DNA rule generator (SM-DNA) is introduced. Simulations and results show that the proposed 3C3R encryption algorithm is robust against all well-known attacks particularly for the known-plaintext attacks, statistical attacks, brute-force attacks, differential attacks, and occlusion attacks, etc. Also, unlike earlier encryption algorithms, the 3C3R has no security vulnerability.
Highlights
With the vast improvement of network and communication technology, communications were improved significantly
To conquer the issue of low sensitivity to the secret key or low security against known plain or cipher-text attacks, this paper introduced a 3C3R robust image encryption algorithm with adequate security level against well known attacks
Uniform histogram and ideal cumulative entropy 8.00 for some images are the proof of robustness and better security of an image by 3C3R
Summary
With the vast improvement of network and communication technology, communications were improved significantly. Communication for multimedia content, especially the image content over the Internet has become more and more chronic. The security of the multimedia has a serious risk in the progression of communication because of the openness and distribution of the Internet. The public has to take great care in terms of confidentiality and security of multimedia communication [1]. Image encryption is one of the most efficient and frequent strategies for digital information protection. Greater and more new techniques are proposed for image encryption, which pursuits to reduce image content’s redundancy by means of distinctive operations, such as DNA-based encryption operations [2] and chaos-based ciphers [3,4]
