“…In [24], the Arnold cat map is utilized to strongly eliminate the correlation among adjacent pixels and logistic map plays a key role in confusing the pixels between plain and cipher image. In [23], the block based shuffling and masking are done to make the system immune against differential and brute force attacks. Though these schemes achieve better security compared with traditional encryption system, they are still inefficient to perform effective encryption.…”

“…For instance, a novel full and selective chaos-based image encryption scheme suitable for medical image encryption applications is given in [11], where the speed is improved employing a pseudorandom matrix, but only simulation results are provided to demonstrate the suitability for real-time secure image communication; in [12], another novel image encryption scheme is given using a chaotic true random bits generator (TRBG), so that the bit sequence is used to encrypt and decrypt grayscale images; in [14], the authors present a color image encryption algorithm based on total plain image characteristics that can be implemented in realtime applications where a high security is required; a the channel goes to zero, e.g., using 2 scrolls, it was −0.3334, and using 6 scrolls, it was −0.0314. In addition, realizing more scrolls requires a minimum percentage of the used resources in the DSP block 18-bit elements, e.g., 2% of difference using 6-scroll attractors versus using 2-scroll ones.…”

“…Recently, image processing is an interesting research topic [11][12][13][14], and from the successful application of FPGAs to implement chaotic oscillators [2,15,16], we introduce the synchronization of two chaotic oscillators to design a secure communication system for which our experimental results demonstrate its suitability for image transmission.…”

The hardware realization of a chaotic communication system from the description of continuoustime multi-scroll chaotic oscillators is introduced herein by using field-programmable gate arrays (FPGA). That way, two multi-scroll chaotic oscillators generating 2 and 6 scrolls are synchronized by applying Hamiltonian forms and observer approach. The synchronized master-slave topology is used to implement a secure communication system by adding chaos to an image at the transmission stage and by subtracting chaos at the recover stage. The FPGA realization begins by applying numerical methods to solve the system of equations describing the whole chaotic communication system. Further, the replacement of multipliers by single constant multiplication blocks reduces the use of hardware resources and accelerates the processing time as well. Using chaotic oscillators with 2 and 6 scrolls, three kinds of images are processed: one in black and white and two in gray tones. Finally, the experimental results confirm the appropriateness on realizing chaotic communication systems for image processing by using FPGAs.

“…However, this widespread use and the growth of the amount of data are also a great challenge for the security design of image encryption algorithms, especially for such private images as medical images [1,2]. Traditional encryption methods such as the Data Encryption Standard, the International Data Encryption Algorithm (DES) [3], and the Advanced Encryption Standard (AES) [4] are not suitable for image encryption; those methods including chaotic encryption method perform poorly due to their low efficiency [5].…”

This paper proposes a new image scrambling algorithm based on the periodic characteristics of the Josephus ring. The algorithm composes the pretreatment part of the entire image encryption system and scrambles the rows and columns of the plain image. The Josephus scrambling algorithm is adjustable by using three kinds of parameters: step, m 0 , and n. Different values affect the size of the periodic value of the Josephus ring. In this paper, we focus on the method of determining the period of the Josephus cycle when the parameters are set and the Josephus rule space under arbitrary parameters. Because the Josephus ring is a mathematical problem, we analyze it using the group theory of modern algebra. After the Josephus scrambling, the plain image is encrypted. Because a CA is suitable for image encryption, the encryption part adopts a CA encryption algorithm using a one-dimensional, four-neighbor CA, which has chaotic behavior at the rules of 9d62 (hex). Finally, the number of pixels change rate, the unified averaged changed intensity test, and correlation detection are carried out on the experimental results. The results show that the use of the Josephus scrambling algorithm greatly improves the security of the entire encryption system.
