In recent years, with the continuous growth of science and technology in our country, we are exposed to more and more information. Computers are gradually coming into people's lives and constantly changing people's way of life. The scale of emerging services is expanding rapidly. Social networks, big data, Internet of Things and cloud computing are all developing rapidly. However, with the continuous development of the times, so far, the research of big data encryption algorithm has been far from meeting people's needs. With large-scale data volume and information volume, GB, TB and PB have far exceeded the general data statistics volume; at the same time, the surge of redundant data information is also significant. Therefore, it is imperative to solve the problem of redundant data information. In such a large scale of data sets, we should use scientific and effective methods to analyze data and make decisions, and create a stable big data analysis model to deal with the relationship between data.

Lightweight devices such as smart cards and RFID tags have a very limited hardware resource, which could be too weak to cope with asymmetric-key cryptography. It would be desirable if the cryptographic algorithm could be optimized in order to better use hardware resources. In this paper, we demonstrate how identity-based encryption algorithms from bilinear pairing can be optimized so that hardware resources can be saved. We notice that the identity-based encryption algorithms from bilinear pairing in the literature must perform both elliptic curve group operations and multiplicative group operations, which consume a lot of hardware resources. We manage to eliminate the need of multiplicative group operations for encryption. This is a significant discovery since the hardware structure can be simplified for implementing pairing-based cryptography. Our experimental results show that our encryption algorithm saves up to 47 percent memory (27,239 RAM bits) in FPGA implementation.

As technology continues to advance, safeguarding personal privacy and information security has become increasingly critical. Facial image encryption algorithms involve encrypting and decrypting facial images to prevent unauthorized access and malicious use. Fuzzy computation is a practical solution for many decision problems in facial recognition encryption algorithms. To this end, this study proposes the use of fuzzy two-dimensional kernel principal component analysis for facial recognition and chaotic MapReduce for facial image encryption. The study introduces fuzzy membership functions to handle uncertainty in two-dimensional kernel principal component analysis. Experimental results indicated that the accuracy of the fusion fuzzy calculation and two-dimensional kernel principal component analysis method exceeded 75%, which was 13-37% higher than the comparison method. Furthermore, the proposed method combining chaotic systems and MapReduce has a uniform histogram distribution and runs 50% faster than the comparison method. Consequently, it is evident that the method proposed by the research institute is both feasible and efficient for safe facial image analysis.

A novel implementation of encryption algorithms based on FPGA gates is described in this paper. The encryption algorithm is focused on different FPGA devices with the same number of cascaded NOT gates but have different time delays to signals. The cascaded NOT gates are achieved by programming. These different time delays are the theoretical basis of the encryption algorithm. In this paper, we will firstly introduce the core idea of the algorithm. And then, the implementation of the encryption algorithm, IC design and Embedded Software will be explained in detail. At the end of the paper, the factors which affect the encryption will be analyzed.

Cloud computing is an emerging technology has grown a lot for virtualization and provides many services over the internet such as software as a service, platform as a service, infrastructure as a service and many more services which reduce the cost expenses and operating expenses. Now by using these services, data can store online in the cloud, then automatically a security concern will arise about data. Many protection techniques have been proposed till now. The best options available is encrypting the data before storing in third party cloud database and again decrypt the data after retrieving from the cloud. We introduce a more economical and robust encryption technique which allows a third-party cloud server to shield user data more expeditiously.

This paper describes an encryption algorithm based on a polynomial system of residual classes. We study the FPGA bitstream implementation on the Xilinx and 16-nm UltraScale™ ASIC architecture which enables floating-point operation, multi-processing, parallelism, pipelining, highperformance computing, etc. The software-based bitstream encryption and on-chip decryption are performed with the stored encryption key and encrypted bitstream, generated by a Vivado tool. The self-authenticating algorithms with a symmetric key are investigated. The encryption algorithms are implemented using the polynomial system of residual numbers. Data encryption in a residual number system is effectively implemented by ASICs. Design of irreducible polynomial is proposed and discussed. Our developments and findings are empowered by the low-power FinFET FPGA architecture.

In order to discuss the synchronization characteristic of a class of the cellular neural network and Lorenz hyper chaotic systems. This paper puts forward on the control method between different chaotic and dimensions system, using the controller and base on stability theory of Lyapunov to analysis of the synchronization stability. Finally a synchronization encryption algorithm for audio is presented as a new design. The simulation results show that there is not much correlation between the waveform of the audio document after it's encrypted with that of the original one. By comparing the spectrum, it further testifies that the encryption effect of this design is remarkable.

In the present time of increasing digital communication, the images are widely used over the multimedia networks for sharing of information. At the same time to ensure the security of images during transmission of data becomes a great challenge for cryptographers. In this paper, a new multi-phases image encryption algorithm based on the RSA cryptosystem and modified random matrix affine cipher (MRMAC) is proposed. The Chen's hyperchaotic system and Arnold cat map are used to create more distraction from the relationship between the original image and ciphered image. The Chen's hyperchaotic system is used for diffusion, whereas the Arnold cat map is used for increasing the confusion among pixels. In this proposed algorithm the image ciphering is carried out in different phases. Firstly the given image is encrypted using RSA algorithm with large primes. Secondly, in modified RMAC, random blocks of random entries using Chen's hyperchaotic system are generated and are diffused with image pixels using bitwise XOR operation. Also, we create confusion of pixels within these diffused blocks, and confusion of blocks as well using parameters of MRMAC. The randomness in the algorithm is improved using MRMAC is advantage against differential attacks. Further, the Arnold cat map is used to enhance the level of confusion. Since, it is tremendously difficult to factorize the product of large prime numbers, therefore, the security of data in RSA algorithm increases tremendously. For the proper decryption of ciphered images, one must have exact values of keys and their correct order. It is impossible to guess the decrypted image even with a very small change in a single key. The results obtained in statistical and security analysis shows that the proposed algorithm has a huge key space, extreme security and key sensitivity, which proves that scheme is efficient and highly secure.

In this paper, enhancement of an existing optical simultaneous fusion, compression and encryption (SFCE) scheme in terms of real-time requirements, bandwidth occupation and encryption robustness is proposed. We have used and approximate form of the DCT to decrease the computational resources. Then, a novel chaos based encryption algorithm is introduced in order to achieve the confusion and diffusion effects. In the confusion phase, Henon map is used for row and column permutations, where the initial condition is related to the original image. Furthermore, the Skew Tent map is employed to generate another random matrix in order to carry out pixel scrambling. Finally, an adaptation of a classical diffusion process scheme is employed to strengthen security of the cryptosystem against statistical, differential, and chosen plaintext attacks. Analyses of key space, histogram, adjacent pixel correlation, sensitivity, and encryption speed of the encryption scheme are provided, and favorably compared to those of the existing crypto-compression system. The proposed method has been found to be digital/optical implementation friendly which facilitates the integration of the crypto-compression system on a very broad range of scenarios.
