Wireless body area networks (WBANs) are an exciting technology that will revolutionize physiological monitoring in the coming years. However, the widespread deployment of WBANs is restricted by steep energy limitations. Furthermore, they require acute security measures to protect user medical data. We aim to measure the energy consumption of a cellphone as it transmits and encrypts data in a mock WBAN scenario. We evaluated the impact of various design parameters in an effort to discover the ideal WBAN operational protocols. In conclusion, we recommend an optimal file size strategy, data communication network, and encryption algorithm that minimize energy consumption and enhance WBAN operation.

The desire for new algebraic structures is always an interesting area of research for the design and development of new information confidentiality mechanisms. Confidentiality mechanism keeps information secure from unauthentic users and transforms information into a ciphered format that cannot be easily deciphered. The key components of data security are encryption/decryption algorithms. encryption/Decryption algorithms depend on mathematical structures used for substitution box (S-box) and key scheduling. In the present research, the Galois ring-based S-box is used in the Blowfish confidentiality technique and practically implement for electro-optical satellite image ciphering. The results of data ciphering are compared with Blowfish cipher with the standard S-box. Ciphered images have been evaluated by standard tests such as histogram equalization, randomness, correlation, and differential assaults analysis. These tests depict that the ciphered data by Blowfish based on Galois ring-based S-box is more secure and the security is achieved in the fourth round for electro-optical satellite images. Test results for satellite images illustrate that by less execution time found better satellite image ciphering in the fourth ciphering round by using the proposed scheme. With this addition, subsequent steps of the existing algorithm were modified which add more robustness to our digital information. Security analysis of this tested mechanism added more robustness to the confidentiality of digital images. The results of the anticipated ciphering scheme clarify the better performance as compared to the standard Blowfish algorithm for satellite images. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

Our approach permits to capitalize the expert's knowledge as business rules by using an agent-based platform. The objective of our approach is to allow experts to manage the daily evolutions of business domains without having to use a technician, and to allow them to be implied, and to participate in the development of the application to accomplish the daily tasks of their work. Therefore, the manipulation of an expert's knowledge generates the need for information security and other associated technologies. The notion of cryptography has emerged as a basic concept in business rules modeling. The purpose of this paper is to present a cryptographic algorithm based approach to integrate the security aspect in business rules modeling. We propose integrating an agent-based approach in the framework. This solution utilizes a security agent with domain ontology. This agent applies an encryption/decryption algorithm to allow for the confidentiality, authenticity, and integrity of the most important rules. To increase the security of these rules, we used hybrid cryptography in order to take advantage of symmetric and asymmetric algorithms. We performed some experiments to find the best encryption algorithm, which provides improvement in terms of response time, space memory, and security.

International Journal of Information and Communication Technology 2024年第7期25卷 57-74页

Traditional chaotic image encryption methods have certain limitations in terms of processing high-dimensional data, computational complexity and attack resistance, which limits their widespread promotion and use in practical applications. To solve these problems, this paper proposes a chaotic colour image encryption method based on differential evolutionary deep learning. Firstly, the security and stability of the image encryption algorithm is enhanced by introducing a six-dimensional cellular neural network (CNN). Secondly, the parameters of the six-dimensional CNN are optimised using differential evolutionary algorithms to improve the complexity and randomness of the chaotic sequences. The experimental results show that compared with the traditional CNN, AES and Chaotic encryption Algorithm, this paper’s method shows significant improvement in NPCR and UACI indicators.

Recently, multimedia has developed and become very important for transferring images securely through public networks. This paper uses the COOT optimization algorithm with compressive sensing (CS) for image encryption. A good method was proposed for encryption using compressive sensing with COOT optimization and chaos to encrypt images and obtain optimal encryption with the least correlation between pixels. This method will strengthen the encryption against various types of attacks. The natural image was sparsed using discreet wavelet transform (DWT) and the FAN transform. The image is divided into several blocks, and CS is applied to each block. The best measurement matrix was obtained using a COOT-optimized algorithm. All blocks are masked to get the compressed image, and the pixels are quantified. Next, the COOT optimization is used to Shuffle the image pixels to achieve the minimum correlation between the pixels. Then, a logistic map will be used to uniform the image pixel values by diffusion to get the final encrypted image. Chen’s chaotic and logistic map initial values are obtained from the input image after its division into four parts by taking a value from each part. The evaluation results obtained for this algorithm showed that it performs highly compared to other conventional methods. The average PSNR for the reconstructed images was 35.244, the average NPCR and UACI were 90.53 and 29.54, respectively, and the average correlation was (D = 0.0018, V = 0.0031, H = 0.0039). The results proved that the method is strong enough and very efficient to withstand attacks. © 2024 River Publishers.

The medical privacy of patients is protected by law. This paper briefly introduces the legal basis of medical privacy protection and the attribute-based encryption algorithm used for encrypting medical privacy data. After that, simulation experiments were conducted to test the encryption efficiency, encryption effectiveness, and security of the algorithm. It was found that the number of identity attributes contained in private data could affect the encryption efficiency of the algorithm. The more attributes, the lower the encryption efficiency. When the number of overlapping identity attributes between the enquirer and the ciphertext met the threshold value, the plaintext could be obtained smoothly;otherwise, it could not be decrypted. The ciphertext obtained by the encryption algorithm could effectively resist brute force cracking. © (2024), (International Journal of Network Security). All rights reserved.

Color Image encryption Based on Chaotic Systems and Dynamic Transformation Matrices

引用

International Journal of Network Security 2024年第5期26卷 867-873页

Matrix transformation has been successfully used in image encryption. However, conventional image encryption algorithms often employ fixed transformation matrices, which limits the randomness and versatility of image encryption. This paper proposes an image encryption algorithm based on dynamic transformation matrices to address this issue. Random variables generated from chaotic sequences correlated with the plaintext are used to select the transformation matrices. As a result, even slight changes in the plaintext or chaotic sequences lead to completely different encryption results. Furthermore, the proposed algorithm combines dynamic transformation matrices with Zigzag transformation to further shuffle the color image’s R, G, and B components, thereby enhancing the encryption effectiveness. Experimental simulations and result analyses demonstrate the algorithm’s strong security and high efficiency. © (2024), (International Journal of Network Security). All rights reserved.

The demand on the security and reliability of the communication and data link of unmanned aerial vehicle (UAV) is much higher since the environment of the modern battlefield is becoming more and more complex. Since the UAV communication link and its reliability evaluation represent an arduous field, we have concentrated our work on this topic. A UAV communication channel is a key factor that can affect the performance of the data link in terms of high data rate and reliable transmission of information. Moreover, the wireless communication channel opens up the door for several types of remote attacks. Therefore, the communication channel between the vehicle and ground control station (GCS) should be secure and has to provide an efficient data link. For this purpose, we have investigated the one-time pad (OTP) encryption technique for a UAV communication system. The comparative results present that OTP has better performance in terms of accuracy and execution time than other encryption algorithms.
