Electronic Health Records (EHRs) are steadily becoming the central information system for the healthcare industry. EHRs are not completely secure and highly vulnerable to the malicious attacks. Blockchain provides an encouraging solution to this problem and with cryptographic algorithms, there is end-to-end encryption and digital signature on the complete architecture of the transactions involved in every healthcare organization. The proposed model provides an immutable and unforgeable transaction record to patients and healthcare institutions to transmit secured data across the cloud server layer. A private and safe environment is created to store physiological data using distributed ledger system using the proposed modified logarithmic-based Rivest-Shamir-Adleman (rsa) algorithm. The performance of the considered system based on defence efficiency and time to decrypt the ciphertext is evaluated. A significant improvement in the parameters is observed to increase by 38.8% as compared to traditional EHR models using rsa algorithm. In addition, the modified rsa algorithm is tested to provide high security levels, thereby making it more robust against two factorization attacks- ciphertext attack and Fermat’s factorization attack with an increased security level. © 2023, The Author(s), under exclusive licence to Bharati Vidyapeeth's Institute of Computer Applications and Management.

An algorithm for substitution box (S-box) construction is proposed by using fractional-order (FO) 4D hyperchaotic system in this paper. Based on hyperchaotic sequences generated by the FO 4D hyperchaotic system, exclusive-or (XOR) operations, and permutation the S-box is constructed. A comprehensive evaluation based on various algebraic criteria demonstrates that the proposed S-box exhibits favorable performance in terms of strict avalanche criterion (SAC), differential approximation probability (DP), nonlinearity (NL), bit independence criterion (BIC), linear approximation probability (LP), fixed point (FP), reverse fixed point (FPr), and correlation immunity (CI). The proposed S-box exhibits excellent NL of 112, comparable to that of the Advanced Encryption Standard (AES) S-box. Furthermore, a novel color image encryption technique is developed to ensure the privacy of color images. The proposed color image encryption algorithm combines Arnold Cat map (ACM), a high-performance generated S-box, Rivest-Shamir-Adleman (rsa) algorithm with 2D Henon chaotic map (HCM). Through rigorous testing, analysis, and comparison with recently reported image encryption algorithms, the suggested algorithm demonstrates its security, efficiency, and resistance to different standard attacks. Notably, the suggested algorithm for color image encryption offers a substantial key space and achieves an approximate correlation of 0 between adjacent pixels. Additionally, the entropy approaches the ideal value of 8.

Recent innovations in cloud computing and the Internet of Things (IoT) have reshaped numerous real-time applications. However, the exchange of sensitive information within these systems requires strong security measures to ensure privacy, confidentiality, and integrity. In the Internet of Vehicles (IoV), which connects vehicles to each other and to servers, securing communication is critical for maintaining system performance and safety. The proposed model tackles these challenges by integrating cryptography and steganography, offering a multi-layered security solution for information exchange in the IoV network. In the proposed model, secret messages are initially encrypted using the Improved rsa (Irsa) technique, followed by a binary reversal of the encrypted data. The Pixel Value Difference (PVD) technique, enhanced with the Pixel Indicator Technique (PIT), is then employed to embed these reversed binary bits into the cover image. This process ensures the security of the hidden data while preserving the quality of the image. Performance evaluations show that the model achieves excellent image imperceptibility after embedding, as evidenced by improved PSNR and SSIM values. It also exhibits strong resistance to various complex attacks, while achieving an average embedding capacity of 3.98 bits per pixel (bpp). Extensive testing confirms the model's effectiveness in preventing steganalysis attempts, making it a reliable solution for secure data hiding in IoV networks. This innovative method safeguards sensitive data's privacy and integrity without compromising system performance.

Despite the development of numerous cryptographic algorithms over the last decade to ensure greater security for the users, the cyberattack forms are still advancing, which creates a challenge for the research community to build more efficient infrastructure. It motivates us to design more advanced algorithms based on a set of matrices that form a group under matrix multiplication, meaning they satisfy the group axioms of closure, associativity, identity, and irreversibility. Specifically, this study explores the application of three cryptographic algorithms on a special linear group of matrices over a ring of integers modulo m. The first algorithm relies on the rsa key exchange algorithm, which we modify to a special linear group. The second is an asymmetric rsa variant of a cryptographic algorithm defined on the co-adjoint orbit of element K belonging to a special linear group. All matrices from the orbit of matrix K have the same order and can be easily encrypted and decrypted by a pair of secret asymmetric cryptographic keys. We apply the Kronecker product of non-Abelian groups to construct an energy-efficient cryptographic algorithm with possible application on sensor networks. Due to the multiplicative property of the Kronecker product, both the encryption and decryption can be performed in parallel over the matrices of low degree. The third one is another rsa variant of a symmetric cryptographic algorithm, which can be encoded with a special linear group to significantly increase its complexity at the stage of non-negative matrix factorization. To encrypt a given set of numbers, we write it in a matrix form with a secret sequence of generators. As a result, the decryption relies on solving a simple system of nonlinear equations. Security of the algorithm lies in its complexity, aimed at building a correct sequence of generators necessary for encryption.

Delving into the dynamic realm of communication networks, the Network Simulator-2 (NS-2) emerges as a versatile, object-oriented, and event-driven mirror, analysing the intricacies of computer network. NS-2, an open-source, is a strong tool for protocol innovation that supports numerous routing protocols designed for both wired and wireless networks in addition to the TCP/IP protocol suite. However, the security frontier has remained a latent challenge amidst its diverse protocol array. This research defiantly explores the security void in NS-2 and presents a novel solution by adding a state-of-the-art security module. Elevating NS-2's prowess, this module seamlessly integrates message integrity and sender authentication features, injecting a muchneeded security boost. We meticulously detail the inner workings of the security modules, the innovative processes deployed, and the simulation and implementation intricacies within NS-2. The limelight is on the propagation of sender authentication protocols and the embodiment of message integrity in wired communication networks. Network Animator steps onto the stage to make the simulation journey more vivid, providing an engaging visual narrative. At its core, this module strives to democratize the integration of Digital Signature features, carving a path toward a more secure NS-2 landscape. This paper augments NS-2's resilience and charts new territories in the dynamic intersection of communication networks and cutting-edge security protocols.

To protect secrecy without compromising data, the study outlines a strong security framework for communications between mobile devices and servers and recommends encryption as the best option. Traditional encryption techniques are not immediately transferable due to the limitations of e-health data, including its size, redundancy, and bandwidth especially when patient data is moving across public networks. Patient privacy may be compromised as a result of this security flaw. Strong encryption measures must be put in place in the healthcare industry to combat this and ensure that confidential patient data may only be retrieved securely and by authorised personnel, protecting data integrity and privacy. To strengthen communication in the healthcare industry, the study presents a new, simplified encryption and decryption technique. We carefully examine, evaluate, and then benchmark this technique against accepted encryption standards. © Bharati Vidyapeeth's Institute of Computer Applications and Management 2024.
