“…Potentially rich dynamic behaviors as defined as [11] Xn+l=sin(axn) and Xn+l=cos(bxn), where the constants a and b are parameters associated with the frequencies of sine and cosine functions, respectively, have been offered by a section of trigonometric functions including sine and cosine maps [12,13]. The chaotic regions is still not sufficient due to periodic characteristics, even though a high complexity in terms of nonlinear dynamics is offered by sine and cosine [14,15].…”

In this study, we propose an innovative image encryption Techniques based on four different image encryption Algorithm. Our methodology integrates scrambling followed by Symmetric and Asymmetric Encryption Techniques, to make the image meaningless or disordered to enhance the ability to confront attack and in turn improve the security. This paper mainly focused on the multiple encryption Techniques with multiple keys on a single image by dividing it into four blocks. So instead of using one Encryption method a combination of four different Encryption Algorithm can make our image more secure. The Encryption is done first by using DNA as secret key, second by using RSA, third by DES and fourth by Chebyshev. The pros and cons for all the Encryption methods are discussed here. Proposed methodology can strongly encrypt the images for the purpose of storing images and transmitting them over the Internet. There are two major benefits related with this system. The first benefit is the use of Different Algorithm with different keys. The second benefit is that even though we are using four different Algorithm for a single image, the time taken for encryption and decryption is few seconds only. Our method is methodically checked, and it shows an exceptionally high level of security with very good image quality.

“…However, some cryptosystems are still cracked [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. The reason is that the performance of chaos dynamics is not fully considered in the design of algorithms [ 19 , 20 , 21 , 23 ]. In order to overcome the shortcomings, hyperchaotic system can be applied to chaotic cryptography [ 23 , 24 , 25 ].…”

In this paper, we construct a five dimensional continuous hyperchaotic system and propose an image encryption scheme based on the hyperchaotic system, which adopts DNA dynamic coding mechanism and classical scrambling diffusion encryption structure. In the diffusion stage, two rounds of diffusion are adopted and the rules of DNA encoding (DNA decoding) are dynamically changed according to the pixel value of the plaintext image, that is, the rules of DNA encoding (DNA decoding) used to encrypt different images are different, which makes the algorithm can resist chosen-plaintext attack. The encryption (decryption) key is only the initial value of the chaotic system, which overcomes the difficulty of key management in the “one time pad” encryption system. The experimental results and security analysis show that the algorithm has some advantages of large key space, no obvious statistical characteristics of ciphertext, sensitivity to plaintext and key and able to resist differential attacks and chosen plaintext attack. It has good application prospects.

“…Thus, these image encryption schemes cannot resist some attacks, such as the chosen/known plaintext. In addition, some image encryption algorithms are inefficient, such as using bit-level image scrambling, DNA encoding mechanism, key related to plaintext Hash value [ 41 , 42 ], and the high-dimensional chaotic system [ 43 , 44 ]. Encryption algorithms with low efficiency are not suitable for some resource-constrained environments, such as mobile social network [ 45 ], sensor network communication environment [ 46 ] and searchable encryption [ 47 ].…”

In order to improve the security and efficiency of image encryption systems comprehensively, a novel chaotic S-box based image encryption scheme is proposed. Firstly, a new compound chaotic system, Sine-Tent map, is proposed to widen the chaotic range and improve the chaotic performance of 1D discrete chaotic maps. As a result, the new compound chaotic system is more suitable for cryptosystem. Secondly, an efficient and simple method for generating S-boxes is proposed, which can greatly improve the efficiency of S-box production. Thirdly, a novel double S-box based image encryption algorithm is proposed. By introducing equivalent key sequences {r, t} related with image ciphertext, the proposed cryptosystem can resist the four classical types of attacks, which is an advantage over other S-box based encryption schemes. Furthermore, it enhanced the resistance of the system to differential analysis attack by two rounds of forward and backward confusion-diffusion operation with double S-boxes. The simulation results and security analysis verify the effectiveness of the proposed scheme. The new scheme has obvious efficiency advantages, which means that it has better application potential in real-time image encryption.Entropy 2019, 21, 790 2 of 20 (or shuffling, scrambling) process plays a role in confusing the relationship between the cipher image and plain image. The function of the diffusion process is to spread the change of one pixel value in the plain image to the whole range of the cipher image. Based on the basic confusion-diffusion architecture, researchers have proposed many novel concrete encryption strategies. In Ref. [18][19][20][21][22][23][24], authors proposed some different permutation strategies for image scrambling aiming at the confusion process. In Ref. [22,[25][26][27][28][29], authors put forward some novel image diffusion algorithm. In Ref. [30][31][32][33][34][35][36], authors adopt new chaotic systems to improve the complexity and randomness of chaotic key streams. Some other cryptographic methods have also been tried by many researchers. For example, some cryptographic algorithms are based on bit-level permutation and diffusion [30], and some algorithms introduce the DNA coding mechanism [37], and some algorithms mainly use S-box to encrypt images [38][39][40]. However, some image encryption schemes exist as obvious security vulnerabilities. Thus, these image encryption schemes cannot resist some attacks, such as the chosen/known plaintext. In addition, some image encryption algorithms are inefficient, such as using bit-level image scrambling, DNA encoding mechanism, key related to plaintext Hash value [41,42], and the high-dimensional chaotic system [43,44]. Encryption algorithms with low efficiency are not suitable for some resource-constrained environments, such as mobile social network [45], sensor network communication environment [46] and searchable encryption [47]. Compared with high-dimensional continuous-time chaotic systems, low-dimensional discrete chaotic systems can generate chaot...
