The Internet of Things has allowed for the connectivity of medical imaging devices to the healthcare sector's data backbone. This development, made possible by the IoT, will speed up the diagnosis and treatment phases of medical care. The increasing reliance on interconnected devices and cloud-based systems creates potential entry points for cyber-attacks and unauthorized access to sensitive medical data which not only jeopardize patient privacy but also have serious implications for patient safety and trust in healthcare systems. Medical images are critical assets in healthcare, and their confidentiality, integrity, and availability are paramount for accurate diagnoses, treatment planning, and patient care. This instigated research related to medical image security in IoT healthcare. For this, we investigated the usage of a cryptography-based network for image encryption and decryption, and its potential application to the safe transmission of medical images through deep learning. In the proposed work, we use a key learning network based on the ResNet-50 architecture to do the mapping between various image representations. Due to the incorporation of these "hidden properties" into the learning model, the encryption technique can be fine-tuned for each specific domain. As a first step in decryption, we use recon-structive networks to convert the encrypted image back into its "plaintext" form. Once the hidden entities have been uncovered, a Return on Investment (ROI) framework can be made available, and data mining can be simplified by drawing directly from the user's local information environment. Imaging tools for gauging therapy is a highly reliable by using the proposed system. We used two different kinds of publicly available datasets, and that helped us succeed in our mission. The comprehensive empirical setup and the findings of the security analysis suggest that the suggested method may give an unprecedented level of security and an unprecedentedly powerful o

In this work, we propose a medical image encryption method. It is based on the Jigsaw transform, cyclic permutations, and a deterministic noise approach to hide visual information in the images. On the other hand, Langton's ant is used to encrypt the images. The method proposed was tested on fundus retinal photographs. The robustness of our algorithm has been proven through several testing, such as statistical analysis (histograms and correlation distributions), visual testing, entropy testing, and keyspace assessment, showing in each one a high-security level.

At the pixel level, several chaos-based image encryption and decryption models have been developed throughout the years. However, due to long-haul, privacy, and security considerations, it has a number of drawbacks, including increased network complexity and low scalability, and actual text cracking avoidance is more challenging. In this study, we have proposed a novel approach for image encryption and decryption. The confusion and diffusion process is performed using fractional-order chaotic maps with the hybrid radiation heat transfer algorithm based sunflower optimization (HRHT-SO) algorithm. The proposed method works for both color and grayscale images. The HRHT-SO algorithm is the combination of both heat transfer search (HTS) and sunflower optimization (SO) algorithms. During the search process, the SO algorithm improves the radiation stage of the HTS model. Further, the DNA sequence improves the performance of image encryption and decryption using fractional-order chaotic maps with the HRHT-SO algorithm. The experimental investigations are carried out by using various parameters such as key sensitivity analysis, keyspace analysis, histogram analysis, correlation coefficient analysis, entropy analysis, PSNR, NPCR, and UACI analysis thereby analyzing the efficiency and complexity of the encryption scheme. Hence, the proposed method outperforms superior performances in all the experiments.

This paper investigates the fixed-time synchronization and the predefined-time synchronization of memristive complex-valued bidirectional associative memory neural networks (MCVBAMNNs) with leakage time-varying delay. First, the proposed neural networks are regarded as two dynamic real-valued systems. By designing a suitable feedback controller, combined with the Lyapunov method and inequality technology, a more accurate upper bound of stability time estimation is given. Then, a predefined-time stability theorem is proposed, which can easily establish a direct relationship between tuning gain and system stability time. Any predefined time can be set as controller parameters to ensure that the synchronization error converges within the predefined time. Finally, the developed chaotic MCVBAMNNs and predefined-time synchronization technology are applied to image encryption and decryption. The correctness of the theory and the security of the cryptographic system are verified by numerical simulation.

A genuine encryption/decryption algorithm has been developed by using a new chaotic circuit, namely modified Chua's circuit (MCC). The importance of MCC is that it exhibits hyper-chaotic behaviour for a large parameter regime due to the double frequency dependent nature. The numbers extracted from the solutions of the MCC are transmitted to the newly developed algorithm for the encryption and the decryption aims. The scrambling feature, which is implemented at the bit level using the MCC has been applied in the algorithm. Following the encryption procedure, the encrypted colored image has been tested by a variety of tests including the secret key size, secret key sensitivity analysis, histogram analysis, correlation analysis, differential analysis, information entropy analysis, noise attack analysis and occlusion analysis. The results are good and provide an efficient technique for the color image encryption and decryption in the theme of secure communication. Besides, it is not time consuming.

encryption is essential for protecting sensitive data, especially images, against unauthorized access and exploitation. The goal of this work is to develop a more secure image encryption technique for image-based communication. The approach uses particle swarm optimization, chaotic map and magic square to offer an ideal encryption effect. This work introduces a novel encryption algorithm based on magic square. The image is first broken down into single-byte blocks, which are then replaced with the value of the magic square. The encrypted images are then utilized as particles and a starting assembly for the PSO optimization process. The correlation coefficient applied to neighboring pixels is used to define the ideal encrypted image as a fitness function. The results of the experiments reveal that the proposed approach can effectively encrypt images with various secret keys and has a decent encryption effect. As a result of the proposed work improves the public key method's security while simultaneously increasing memory economy.

Finite fields are widely used in modern cryptographic architecture. The prominent finite field based symmetric and asymmetric cryptosystems are (ECC) elliptic curve cryptography, RSA, (AES) advanced encryption standard and pairing-based cryptography. The arithmetic operations of a finite field performed efficiently, that meet the design space constraints and execution speed. These aims resolve tremendous challenges, which required interdisciplinary efforts to render the best algorithms, implementations, architectures, and design practices. This study proposes convenient finite field arithmetic based symmetric key cryptosystem for multimedia data security. The scheme is comprised of diffusion and confusion. To execute the diffusion phase the random numbers generation is essential in utilizing the multiplication and inversion operations over the binary Galois field extensions. The main objective of using these operations is to establish substantial randomness with less computational exertions. In addition, a block cipher construction mechanism has been deployed for the confusion phase of the algorithm which generates multiple S-boxes with fewer rounds as compared to the customary block ciphers. Therefore, efficient creation of confusion in multimedia data and hence more security is attained. The experimental results and the time complexity manifest the efficiency of the scheme against various attacks. Also, as a result of a fast and simple implementation of the binary finite field in hardware and software, the proposed cryptosystem is more convenient to implement as compared to the prevailing schemes.

Ensuring information and communication security in military messages, government instructions, scientific experiments, as well as in personal data processing, is critical. In this study, a new hybrid classical-quantum cryptographic scheme to protect image information and communication security is developed by combining a quantum key distribution (QKD) and compressed sensing (CS). This method employs a QKD system to generate true random codes among the remote legitimate users and utilizes these random codes to encrypt and decrypt compressed 3D image information based on the CS algorithm. Therefore, this new technique can provide computational security in the image information transmission process by the encryption and decryption of CS algorithm, and the information and communication security can be evaluated in real time by monitoring the QKD system. Furthermore, this technique can directly transmit and reconstruct the compressed 3D image information based on the modified TwIST algorithm, and thus fewer random codes are required in QKD system, which can improve the information transmission bandwidth. Consequently, this technique not only provides a new application of a QKD system but also extends the CS-based image reconstruction from 2D to 3D. This study may open a new opportunity in the field of information and security communication.
