Usually a complete computer network system has the following components: source of signals, signal host, cryptographic regime, attack, and interceptor. It is more vulnerable to attacks during the operation of the system, so the security of the system becomes more important. In this paper, by constructing a dual BP neural network combinatorial model and applying it to the computer data communication large integer decomposition encryption process, the constructed model is used to analyze the security against digital certificates, digital signatures, and the algorithms employed in the communication process of connected computer network.

encryption is crucial for securing sensitive data during transmission over networks. Various encryption techniques exist, such as AES, DES, and RC4, with AES being the most renowned algorithm. We proposed methodology that enables users to encrypt text messages for secure transmission over cellular networks. This approach utilizes the AES algorithm following the proposed protocols for encryption and decryption, ensuring fast and reliable data protection. This approach ensures secure text encryption and enables users to enter messages that are encrypted using a key at the sender's end and decrypted at the recipient's end, which is compatible with any Android device. SMS are encrypted with the AES algorithm, making them resistant to brute-force attempts. As SMS has become a popular form of communication, protecting personal data, email alerts, banking details, and transactions information. It addresses security concerns by encrypting messages using AES and cryptographic techniques, providing an effective solution for protecting sensitive data during SMS exchanges.

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.

In this paper we construct a new efficient updatable encryption (UE) scheme based on FrodoPKE learning with errors key encapsulation [1]. We analyse the security of the proposed scheme in the backward-leak uni-directional setting within the rand-ind-eu-cpa model. Since the underlying computationally hard problem here is LWE, the scheme is secure against both classical and quantum attacks. © 2024, CC BY-NC-ND.

The security of long-standing cryptographic protocols such as the RSA algorithm is under threat from the emergence of quantum computing, which is transforming the landscape of cryptography. The interaction between RSA and quantum-based threats—specifically, Shor’s Algorithm—is examined in this review. The paper emphasizes how RSA’s security depends on the challenge of factoring big integers after providing a thorough analysis of the algorithm’s creation, encryption, and decryption steps. Large integer factoring is made possible by quantum computing, which breaks this security paradigm by using concepts like superposition. This process is accelerated by Shor’s Algorithm, a quantum instrument that poses a danger to RSA encryption. To counter this threat, the paper emphasizes how urgent it is and supports post-quantum cryptography alternatives. The influence of Shor’s Algorithm on RSA at different key lengths is examined along with vulnerability assessments. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The broad spectrum of cryptography provides secure protocols for communication and data security. These protocols are based on structures of mathematics such as groups, rings and fields. In particular, cyclic groups and its algebraic features are extensively employed. Recent research on algebraic graph theory demonstrates the potential to create novel cryptographic algorithm. This is achieved by modifying graph structures and its algebraic properties. This research paper illustrates a cryptographic algorithm, which is based on the principles of cyclic group and algebraic graph theory. The proposed encryption algorithm employs multiplicative cipher in cyclic group zp integrated with dynamic shifts of vertex in graph. The use of Pseudo Random Number Generator for determining the number of shifts, provides additional layer of security. This is achieved by generating an independent and unrelated key for each plaintext element. Gray scale image is tested based on the proposed algorithm and results are assessed. The obtained cipher image is tested visually and quantitatively which proved as uniform thereby mitigating the statistical attacks. The result of key sensitivity analysis proves the robustness of algorithm. It is has been seen that it is very sensitive even for a small change of single bit in key. It is also evident that the proposed method foils the differential attack. The key space of the methodology is higher than the traditional multiplicative cipher. Overall, the proposed algorithm is proved to be efficient, secured and robust. © 2024, The Authors. All rights reserved.

For many block encryption algorithms, confusion properties are only related to the substitution box (S-box). The S-box is a crucial component of cryptography. The security of the whole system is affected by the Sbox. Consequently, alternative S-box designs and construction methods have been explored in various studies. In this paper, based on the chaotic Rabinovich-Fabrikant fractional order (FO) system, a new method for constructing a strong initial S-box is proposed. To comply with the objective, the numerical results of the FO chaotic Rabinovich-Fabrikant system are provided by using the four-step Runge Kutta method/Adams-Bashforth-Moulton method for a= 0.87,b= 1.1, and alpha= 0.99. A novel key-based permutation technique is also presented to enhance the functionality of the initial S-box and construct the final S-box. A comparison is made between the performance of the substitution boxes (S-boxes) proposed and that of some other existing chaotic S-box designs. It is perceived that the S-boxes obtained by our proposed methods are stronger. The results of the analysis of the initial and final S-box yield favorable statistics, which make sure of its importance in the use of secure communications. Furthermore, the proposed final S-box's effectiveness in image encryption applications is evaluated through the majority logic criterion (MLC), resulting in exceptional outcomes.

Advanced smart grid applications such as wide-area monitoring, protection, and control (WAMPAC), considerably depend on the synchrophasor measurements gathered from different locations of the power grid. These timestamped measurements are provided by Phasor measurement units (PMUs) and phasor data concentrators (PDCs). These devices are optimally deployed at selected nodes in the grid. PMUs and substation PDCs are routable protocol-based network devices and comply with the IEEE C37.118 standard. Since the PMUs generally communicate through a public wide area network, they are vulnerable to cyberattacks. As a result, these vulnerabilities lead to compromised data integrity, confidentiality, and availability of the smart grid. To cover the cybersecurity vulnerabilities in synchrophasor communication and achieve compatibility between the data transfer based on IEEE C37.118.2 with IEC 61850 standard, IEC 61850-90-5 was released. This part of the standard includes security measures to achieve authentication, integrity, and confidentiality if required. In this work, we implemented publisher and subscriber libraries capable of routing secure GOOSE messages while respecting the time delay specifications set by the IEC61850 standard. The performance of encryption and authentication algorithms was assessed and experimentally verified. In addition, the proposed framework's robustness against cyber-attacks was evaluated.

When it comes to delivering IT services to businesses or consumers, the cloud provides a scalable, reliable, and cost-effective option. However, there is an increased risk associated with cloud computing due to the fact that critical operations frequently go to another organization, making it more difficult to preserve privacy and security of data, sustain data and availability, and prove compliance. It is a difficult issue in cloud computing to ensure the security of outsourced data. Data integrity should be verified by the client or an external auditor before being outsourced. Many methods using various techniques, including Proof of Retrievability, proved data ownership, privacy preservation, etc., have been developed for this goal. Various security strategies to address the current security vulnerabilities have been offered in the literature by researchers and impacted companies. Security and privacy concerns in cloud computing are also well reviewed in the literature. Unfortunately, the literature presented works lack the adaptability to counter diverse attacks without undermining cloud security goals. As a corollary, the literature has highlighted security and privacy vulnerabilities without giving suitable technological techniques to alleviate both security and privacy risks. However, studies that provide technological responses to security issues have not provided enough reasoning for the existence of these dangers. The purpose of this article is to discuss potential cloud security and privacy challenges that might arise and need a flexible approach to finding a workable solution. This study provides a comprehensive review of the relevant literature, discussing how safe cloud conflicts have made the suggested models from prior works obsolete while also taking into consideration the works' adaptability to handle future threats. The STRIDE methodology is then used to convey, from the user's point of view, the security concerns associated with cloud computing.

Secure communication in the digital age is necessary;securing audio data becomes very critical since this is normally transmitted across susceptible networks. Traditional approaches to encryption, like Advanced encryption Standard and Rivest–Shamir–Adleman, are pretty solid but mostly too computationally intensive for real-time audio applications. This paper presents a new audio encryption scheme using chaotic systems, characterized by high sensitivity to initial conditions, pseudo-randomness, and determinism. These properties make chaotic systems ideal for generating keys for cryptographic purposes. Indeed, complex keys that would be nearly impossible to reverse-engineer without exact initial parameters can be obtained with them. This methodology first digitizes the audio signal and subsequently encrypts each sample according to chaotic sequences from multiple systems, like 2D Memristive Hyperchaotic Maps and 3D Hyperchaotic Quadratic Maps. The encryption processes enormously increase the randomness of the encrypted audio and blind the original data, demonstrating the strength of the chaotic systems in securing audio information. Simulation of this encryption approach confirms its effectuality in providing strong security for audio data while maintaining efficiency, thus being suitable for real-time applications. The developed encryption schemes show high resistance to differential attacks, while the quality of the encrypted audio remains acceptable after transformation. This result can demonstrate chaotic systems’ potential to provide a secure and efficient solution for audio communications, which has broad applications in telecommunications, military communications, and confidential conferencing systems. This work, described in the paper, thus satisfies the growing demand for robust security in digital communications and opens up avenues of future research toward chaotic parameter optimization and an extension to other forms of data, enhancing the security featur
