In order to hide image information more efficaciously, improve the radio of workpiece and quality of encryption, this paper proposes delayed chaotic neuron dynamical system, extracts a single neuron research model to determine its dynamic properties, analyzes the model's sensitivity, stability and the randomness of the chaotic sequence, and verifies its dynamics feasibility of combining the system with DNA encoding. The single delay neuron can simulate the unknown dynamic behavior and capability in the model in a certain sense which can effectively improve optimization ability and con-vergence speed of the neural to make the network more practical. DNA encoding also offers new train of thoughts and directions for the study of cryptography. In addition, by introducing the functional form of fuzzy number can further enhance the stability and adaptability of chaotic system in un-certain environment, and get more distinct chaotic phenomena. The experimental simulation and comprehensive data analysis of the algorithm are carried out in this paper. The data manifest that the system has a large chaotic range, can pass the randomness test of NIST and TestU01, has high complexity and sensitivity which could effectively avoid noise attacks. The encrypted information entropy of classical images can reach 7.9998, which confirms that it can effectively and safely realize the encryption of digital images.

This paper is a cryptanalysis of a recent proposed image encryption algorithm based on chaotic functions. The cryptosystem is composed of two-stage permutation and one-stage substitution for encryption of the gray scale plain-image. However, by applying chosen plaintext attack which is described in this paper, we show that all the secret parameters can be revealed. In addition, some other security defects of the cryptosystem are also highlighted. Both mathematical analysis and experimental results confirm the feasibility of this attack. As a result, the cryptosystem in this structure cannot be recommended when we need a higher level of security. (C) 2016 Elsevier GmbH. All rights reserved.

The popularity of machine learning, AI and the network has greatly facilitated life, but there are also many security risks, and users' privacy data have been greatly threatened. At present, this kind of problem is generally solved by using big data (BD) security and privacy protection model. However, the traditional BD security and privacy protection model also has its shortcomings. For example, when facing data privacy attacks and big data information intrusion attacks, the protection effect of traditional models is not ideal, and the protection speed for privacy is too slow. Through its shortcomings, the current BD security and privacy protection model is difficult to protect the current data privacy. The research on BD security and privacy protection model based on image encryption algorithm has become a hot field. Because of the advantages of image encryption algorithm in data encryption, it can be applied to BD security and privacy protection model. This paper proposed a BD security and privacy protection model based on image encryption algorithm, which aimed to improve the protection capability of the privacy protection model. The algorithm proposed in this paper was an image encryption algorithm based on chaotic system. Through this algorithm, the pixel correlation coefficient of the image can be reduced more thoroughly, and the user's image privacy and information can be encrypted better. In the test, the protection rates of traditional BD security and privacy protection model and BD security and privacy protection model constructed by image encryption algorithm based on chaotic system against tuple attacks were 75.15% and 82.25%, respectively. Its protection rates against attribute attacks were 77.26% and 82.41%, respectively, and against probabilistic attacks were 76.38% and 81.97%, respectively. It can be seen that the BD security and privacy protection model based on the image encryption algorithm of chaotic system has a higher protection rate against v

In this paper, techniques to improve the overall efficiency of an image encoding algorithm that is specifically designed to be used in Wireless Sensor Networks (WSN) are proposed. The inherent nature of WSN, which contains numerous network nodes each having its computational resources, makes the algorithm is being underutilized due to its sequential nature and hence there is a scope to improve speedup by applying the concepts of parallelization on it. The other avenues which are pertinent to the task are the usage of GPU for computation of large arrays as well as the concept of cluster computing to run the algorithm on a cluster of nodes. Another point of importance for such an algorithm is the utilization of memory and how to make its usage more efficient. Hence, the concept of pre-allocation is also applied to the algorithm to make it run faster. An in-depth study of the algorithm is conducted by considering various parameters such as the size and complexity of the key, histogram analysis, correlation values, etc.

This paper proposes a chaotic encryption algorithm based on Latin squares and adaptive Z-diffusion. First, in order to improve the defects of the traditional Sine system, two-dimensional enhance Sine chaotic system (2D-ESCS) is designed. In terms of bifurcation diagram, Lyapunov exponent and NIST, we can observe that 2D-ESCS have continuous and large chaotic ranges. Second, the generation of Latin squares through pseudorandom sequences generated by 2D-ESCS and then perform scrambling operation with the image. Third, adaptive Z-diffusion depends on the location of the pixels. the cipher image is calculated by different combinations of pseudorandom numbers, plain images pixel values and intermediate cipher image pixel values. Finally, simulation experiments and security analysis show that the proposed algorithm has a high security level to resist various cryptanalytic attacks and a high execution efficiency.

image encryption can effectively prevent unauthorized users from stealing personal information. Attackers usually analyze the information of the encrypted image according to the strong correlation between image pixels and use it as the breakthrough point of the image encryption algorithm. How to destroy the strong correlation of pixels is a hot topic of current research. In this paper, we propose a novel and simple encryption scheme that is no less effective than other algorithms, called Joseph shift encryption (JSE). To enhance the effectiveness of image encryption, we propose the static Joseph shift encryption (S-JSE) and the dynamic Joseph shift encryption (D-JSE) algorithms. S-JSE can decrease the dimension of the image and shift with the generated Joseph sequence group, then the encrypted image can be generated. D-JSE can increase the number of iterations on the basis of S-JSE, and the Joseph sequence of each iteration is different. Furthermore, the encrypted sequence is scrambled according to the Joseph mapping table and upgraded the dimension to complete the encryption. We analyze the effectiveness of the proposed S-JSE including the impact of the key selection on the effect of image encryption, and the encryption security. Thereafter, we utilize the proposed D-JSE to improve the security of grayscale and color image and verify the effectiveness of the proposed algorithm by extensive and comprehensive experiments in terms of correctness verification, histogram equalization and information entropy, adjacent pixel correlation, plaintext sensitivity, key sensitivity, encrypted image anti-interference, key space, encryption time and defense against special image attacks

The problems of vulnerability of the image encryption algorithm are proposed by the researchers analyzing the algorithm concerning pixel permutation and diffusion based on the hyper-chaos. Not given any knowledge of the key value, these vulnerable parts are attacked by three plaintext matrixes with their own characters, causing the ciphered-image being recovered at a low computing pay in which the theoretical analysis process, practical block diagram and simulation results of the chosen plaintext attacking are given. According to the results, these imperfect parts cause that the algorithm can not resist the chosen plaintext attacking.

In this paper, we construct a quantum logistic-tent map and extend it to the fractional order. Using bifurcation portrait, Lyapunov exponent spectrum, and spectral entropy, its nonlinear characteristics are investigated. The analysis results illustrate that this fractional map possesses higher nonlinearity and is better suited for image encryption. Thus, the fractional quantum logistic-tent map as well as compressed sensing (CS) are utilized to create an image cryptosystem. The measurement matrix of CS is generated by this fractional map. Moreover, the map is also used for confusion and diffusion. In this encryption algorithm, the plaintext image is first sparsely represented with discrete wavelet transform (DWT). We then segment and reassemble the sparse image, and apply Arnold map to confuse the reassembled image. Next, a partial Hadamard matrix samples the image, and the pixel value is quantified with limited accuracy. Finally, the pixels of the image are diffused by two-way diffusion. This scheme integrates sparsity, block exchange, confusion, measurement acquisition, and diffusion. The simulation experiment finds that this image encryption approach possesses good security and compression performance.

At present, the image encryption algorithm based on the bit-plane has the problem that the encryption speed and the encryption effect cannot be well balanced. To address the problem, an image layered scrambling encryption algorithm is proposed in this paper. First, a new one-dimensional Cosine Logistic compound chaotic map (1DCLC) is proposed. Several characteristics of the new chaotic map are analyzed by using various measures, such as bifurcation diagram, Lyapunov exponent, sample entropy etc. And the results show that the novel chaotic map has a better chaotic performance. Second, based on the chaotic map, an image encryption algorithm is proposed. The algorithm first performs an XOR encryption operation on the image. Second, the layered scrambling is applied to the XOR encrypted image. Then the layered and scrambled image is recombined for the second XOR encryption operation. In particular, in the layered scrambling, not only can the position of the pixel be changed but also the value of the pixel can be modified, which improves the security of the algorithm. In addition, in order to defend against various plaintext attacks and increase the security of the overall algorithm, the Hash function is introduced to update the key of the proposed algorithm. Finally, the original algorithm is improved and the improved algorithm's ability to resist differential attacks is analyzed. The experimental simulation and security test results show that the proposed encryption algorithm has a comparable encryption effect and a faster encryption speed.
