“…Chaotic systems have initial value sensitivity, which means that small changes in the input value will cause unpredictable changes in the output value. The Lyapunov exponent (LE) is an important index to evaluate the nonlinear dynamic behavior of chaotic systems [24]. LE can reflect the separation degree of adjacent orbits with time, which can effectively indicate whether there is chaotic behavior in the system.…”

This paper introduces a novel one-dimensional sine chaotic system (1DSCS) with large parameter interval. The evaluation of 1DSCS indicates that the system has good chaotic characteristics and large parameters space. Based on 1DSCS, a new image encryption scheme is proposed. First, the image is scrambled by the row and column indexes, and then scrambled by the dynamic parameters Arnold map. This scheme avoids the inadequacy of row-column index scrambling and the periodicity of Arnold map. Second, four highly sensitive dynamic diffusion formulas related to plaintext are designed, and the dynamic formulas are selected through the chaotic sequence generated by 1DSCS. Third, the scheme proposed in this paper can also be applied to color image encryption. The experimental results demonstrate that the 1DSCS system is suitable for image encryption and the encryption scheme has good security to resist common attacks.

The majority of imaging techniques use symmetric and asymmetric cryptography algorithms to encrypt digital media. Most of the research works contributed in the literature focus primarily on the Advanced Encryption Standard (AES) algorithm for encryption and decryption. This paper propose an analysis for performing image encryption and decryption by hybridization of Elliptic Curve Cryptography (ECC) with Hill Cipher (HC), ECC with Advanced Encryption Standard (AES) and ElGamal with Double Playfair Cipher (DPC). This analysis is based on the following parameters: (i) Encryption and decryption time, (ii) entropy of encrypted image, (iii) loss in intensity of the decrypted image, (iv) Peak Signal to Noise Ratio (PSNR), (v) Number of Pixels Change Rate (NPCR), and (vi) Unified Average Changing Intensity (UACI). The hybrid process involves the speed and ease of implementation from symmetric algorithms, as well as improved security from asymmetric algorithms. ECC and ElGamal cryptosystems provide asymmetric key cryptography, while HC, AES, and DPC are symmetric key algorithms. ECC with AES are perfect for remote or private communications with smaller image sizes based on the amount of time needed for encryption and decryption. The metric measurement with test cases finds that ECC and HC have a good overall solution for image encryption.

“…As a non-linear component, S-box is widely used in AES and DES algorithm to enhance the effect of confusion. This encryption technology is widely used in image encryption because of its simple implementation and easy embedding [28,29,30]. Such as, Ben Farah et al [28] proposed an image encryption scheme based on mixed chaotic map and optimized s-box.…”

An Efficient and Secure Image Encryption Algorithm Based on Non- Adjacent Coupled Maps

et al. 2020

In this paper, an image encryption algorithm based on non-adjacent coupled map lattices is designed. Compared with coupled map lattices, non-adjacent coupled map lattices have few periodic windows in bifurcation, and larger parameter range in chaos dynamics. Combined with the proposed chaotic system, a new alternative encryption structure between permutation, diffusion and substitution is proposed to improve the security and encryption efficiency of the algorithm. In the diffusion process, multiplication operation in GF (257) and addition operation in GF (2) based on look-up table are adopted, which improves the encryption efficiency and enhances the permutation effect by choosing pixel value in Latin Square during the diffusion process. Moreover, based on the good cryptographic characteristics of the s-box, a dynamic sbox related to plaintext is constructed to substitute plaintext pixels. Experimental results and security analysis show that the proposed encryption scheme can resist all types of typical attacks and has good encryption effect.
