As technology has progressed, people have begun to perform various daily tasks by using different online applications and services, which has led to a large number of incidents of identity theft. These unpleasant events incur expensive costs for individuals, companies, and authorities, and as a result, identity theft concerns them greatly. Although scholars of information security have devoted their efforts to developing technology to prevent identity theft, it is not clear what factors influence an individual’s security protection motivation. Few empirical and behavioral studies on this topic have been conducted. To fill this gap, this study extends the protection motivation theory with anxiety, elucidating the influences of a future negative event (identity theft) on an individual’s current emotion, which in turn determines protection motivation. This study proposes a research model that explores the influences of threat appraisal (perceived severity and perceived susceptibility) and coping appraisal (response efficacy and self-efficacy) on anxiety, which affects protection motivation. The results in this study provide a more holistic comprehension of identity theft and protection motivation, and can be referred to when developing efficient security guidance and practices.

The globe is observing the emergence of the Internet of Things more prominently recognized as IoT. In this day and age, there exist numerous technological apparatuses that possess the capability to be interconnected with the internet and can amass, convey, and receive information concerning the users. This technology endeavors to simplify existence, however, when the users information is the central concern for IoT operation, it is necessary to adhere to security measures to guarantee privacy and prevent the exploitation of said information. The customary cryptographic algorithms, such as RSA, AES, and DES, may perform adequately with older technologies such as conventional computers or laptops. Nevertheless, contemporary technologies are heading towards quantum computing, and this latter form possesses a processing capability that can effortlessly jeopardize the aforementioned cryptographic algorithms. Therefore, there arises an imperative necessity for a novel and resilient cryptographic algorithm. To put it differently, there is a requirement to devise a fresh algorithm, impervious to quantum computing, that can shield the information from assaults perpetrated utilizing quantum computing. IoT is one of the domains that must ensure the security of the information against malevolent activities. Besides the conventional cryptography that enciphers information into bits, quantum encryption utilizes qubits, specifically photons and photon polarization, to encode data.

The result from second step converted to DNA then applying AddRoundKey with DNA key. The evaluation performance results proved that the proposed algorithm cipher the important data with high security levels.

Operational technology (OT) systems use hardware and software to monitor and control physical processes, devices, and infrastructure - often critical infrastructures. The convergence of information technology (IT) and OT has significantly heightened the cyber threats in OT systems. Although OT systems share many of the hardware and software components in IT systems, these components often operate under different expectations. In this work, several hardware root-of-trust architectures are surveyed and the attacks each one mitigates are compared. Attacks spanning the design, manufacturing, and deployment life cycle of safety-critical operational technology are considered. The survey examines architectures that provide a hardware root-of-trust as a peripheral component in a larger system, SoC architectures with an integrated hardware root-of-trust, and FPGA-based hardware root-of-trust systems. Each architecture is compared based on the attacks mitigated. The comparison demonstrates that protecting operational technology across its complete life cycle requires multiple solutions working in tandem.

With the advances in 5G communication and mobile device, internet of drones (IoD) has emerged as a fascinating new concept in the realm of smart cities, and has garnered significant interest from both scientific and industrial communities. However, IoD are fragile to variety of security attacks because an adversary can reuse, delete, insert, intercept or block the transmitted messages over an open channel. Therefore, it is imperative to have robust and efficient authentication and key agreement (AKA) schemes for IoD in order to to fulfill the necessary security requirements. Recently, Nikooghadm et al. designed a secure and lightweight AKA scheme for internet of drones (IoD) in IoT environments. However, we prove that their scheme is not resilient to various security threats and does not provide the necessary security properties. Thus, we propose the essential security requirements and guidelines to enhance the security flaws of Nikooghadm et al.’s scheme.

On this basis, we propose a UAV honeypot active defense strategy based on reinforcement learning. The active defense model of UAV honeypot is described of four dimensions: state, action, reward, and strategy. The simulation results show that the UAV honeypot strategy can maximize the capture of attacker data, which has important theoretical significance for the research of UAV information security.

The energy revolution is primarily driven by the adoption of advanced communication technologies that allow for the digitization of power grids.

Substations are the electricity transmission systems’ most critical assets. Substation outages caused by cyber-attacks produce widespread power outages impacting thousands of consumers. To plan and prepare for such rare yet high-impact occurrences, this paper proposes an integrated defense-in-depth framework for power transmission systems to reduce the risk of cyber-induced substation failures. The inherent resilience of physical power systems assesses cyber-attacks’ impact on critical substations. The presented approach integrates the physical implications of substation failures with cyber vulnerabilities to analyze cyber-physical risks holistically.

Cyber security is a critical problem that causes data breaches, identity theft, and harm to millions of people and businesses. As technology evolves, new security threats emerge as a result of a dearth of cyber security specialists equipped with up-to-date information. It is hard for security firms to prevent cyber-attacks without the cooperation of senior professionals. However, by depending on artificial intelligence to combat cyber-attacks, the strain on specialists can be lessened. as the use of Artificial Intelligence (AI) can improve Machine Learning (ML) approaches that can mine data to detect the sources of cyberattacks or perhaps prevent them as an AI method, it enables and facilitates malware detection by utilizing data from prior cyber-attacks in a variety of methods, including behavior analysis, risk assessment, bot blocking, endpoint protection, and security task automation. However, deploying AI may present new threats, therefore cyber security experts must establish a balance between risk and benefit. While AI models can aid cybersecurity experts in making decisions and forming conclusions, they will never be able to make all cybersecurity decisions and judgments.
