“…Furthermore, the proposal in this work has larger space key, demonstrating the capability of the proposed cryptosystem to resist against well-known attacks effectively as shown in Table 10. Another motivational and major benefit of using our cryptosystem is the ability of real implementations by an integrated circuit such as a field-programmable gate array (FPGA), especially throughput Finite Field multipliers [54]. Considering this superiority, the proposed cryptosystem can guarantee the privacy and security of patients during WCE work.…”

Privacy preservation has become a prerequisite for modern applications in the cloud, social media, Internet of things (IoT), and E-healthcare systems.In general, health and medical data contain images and medical information about the patients and such personal data should be kept confidential in order to maintain the patients' privacy. Due to limitations in digital data properties, traditional encryption schemes over textual and structural one-dimension data cannot be applied directly to e-health data. In addition, when personal data are sent over the open channels, patients may lose privacy of data contents.Hence, a secure lightweight keyframe extraction method is highly required to ensure timely, correct, and privacy-preserving e-health services. Besides this, it is inherently difficult to achieve a satisfied level of security in a cost-effective way while considering the constraints of real-time e-health applications. In this paper, we propose a privacy preserving chaos-based encryption cryptosystem for patients' privacy protection. The proposed cryptosystem can protect patient's images from a compromised broker. In particular, we propose a fast

“…Aperi-odic orbits, generating identical statistical patterns, give dynamics of the chaotic attractor. Such designs may use substitution techniques to obscure simple signals [38]. On the other hand, diffusion is closely linked to chaotic systems sensitivity to starting conditions and parameters of regulation.…”

The concept Web of Things (WoT) goes well beyond the emphasis on the Internet as a means of sharing data, instead of introducing all resources and connections involving computers, data, and people to the Web. It, therefore, focuses on a range of problems and opportunities, thus paving the way for several exciting industries applications. In cryptography a range of main characteristics of chaotic systems such as non-linearity, initial condition sensitivity, and mixing properties are available. These characteristics provide an essential connection between cryptography and chaos. GOST block cipher is based on secret key secrecy. However, when the encryption process with the same key is used for plaintext, the same cipher text is created. Message replication can be easily detected by an adversary who is a bad link in every communication. In this paper, propose to use a 5d chaotic system combined with GOST block cipher to create a new secure Web of Things (WoT) cryptography system. The 5D chaotic system was used to generate chaotic random keys used in GOST algorithm to provide proper security with as high hardness randomly enhances the NIST fifteen statistical tests and modifies key schedule as security operations.

“…Figure 4 shows that the modified algorithm using bit permutation has reduced the encryption of the standard AES 16.88% and reduced the decryption of the standard AES by 11.96% for encrypting images. A faster encryption algorithm for images is needed to provide better security of digital images [22][23].…”

<span>The paper proposes a modification of the Advanced Encryption Standard (AES) to address its high computational requirement steaming from the complex mathematical operations in the MixColumns Transformation which makes the encryption process slow. Bit Permutation was used instead of the MixColumns Transformation since the use of bit permutation in an encryption algorithm achieves efficiency by providing minimum encryption time and memory requirement. Results of the study showed that the modified AES algorithm exhibited faster encryption by 18.47% and faster decryption by 18.77% for text files. The modified AES algorithm also resulted to 16.53% higher avalanche effect compared with the standard AES thus improving the security performance. Application of the modified AES in encrypting images in Cipher Block Chaining mode showed that the modified algorithm also exhibited 16.88% faster encryption and 11.96% decryption compared with the standard AES. Likewise, modifying the algorithm achieved the ideal result in the histogram analysis, information entropy, the correlation coefficient of adjacent pixels to resist statistical attack. The ideal value in number of pixels change rate and unified average change intensity were also achieved making the modified algorithm resistant to differential attack. These results show that modifying AES by using bit permutation to replace MixColumns Transformation was able to address the high computational requirement of the algorithm resulting in a faster and more secure encryption algorithm for text files and images</span><span>.</span>
