Item Embargo ENHANCING LOCATION INFORMATION PRIVACY AND SECURITY IN IoBT USING DECEPTION-BASED TECHNIQUES(Florida Atlantic Uniiversity, 2024-09) Alkanjr, Basmh; Imadeldin, MahgoubIoBT stands for the Internet of Battlefield Things. This concept extends the principles of the Internet of Things (IoT) for military and defense use. IoBT integrates smart devices, sensors, and technology on the battlefield to improve situational awareness, communication, and decision-making in military operations. Sensitive military data typically includes information crucial to national security, such as the location of soldiers and equipment. Unauthorized access to location data may compromise operational confidentiality and impede the element of surprise in military operations. Therefore, ensuring the security of location data is crucial for the success and efficiency of military operations. We propose two systems to address this issue. First, we propose a novel deception-based scheme to enhance the location-information security of IoBT nodes. The proposed scheme uses a novel encryption method, dummy IDs, and dummy packets technology. We develop a mathematical model to evaluate our scheme in terms of safety time (ST), probability of failure (PF), and the probability of identifying the real packet in each location information update (PIRP). Then, we develop NetLogo simulations to validate the mathematical model. The proposed scheme increases ST, reduces PF and PIRP. We develop a scheme to protect the node's identity using dummy ID, silence period, and sensitive area’s location privacy enhancement concepts. We generate a pseudonym location for each node in the IoBT environment to protect the node's real location information. We propose a new metric called the average probability of linkability per dummy ID (DID) change to assess the attacker's effectiveness in linking the source node with its new DID following the silent period. We develop Matlab simulations to evaluate our scheme in terms of average anonymity and average probability of linkability per DID change. The results showed further privacy enhancement by applying the sensitive area concept. Tampering with location information, such as falsification attacks, can lead to inaccurate battlefield assessments and personnel safety risks. Thus, we design ANFIS and ensemble methods for detecting position falsification attacks in IoBT. Using the VeReMi dataset, our method achieved high detection accuracy while reducing false negative rate and computation complexity. Cross-validation further supports the reliability of our model.32 0Item Restricted A Systematic Review of Renewable Energy Policy and Development Strategies in the Kingdom of Saudi Arabia(University of Shaffield, 2024-09) Alqarni, Mohammed; Ankit, KumarThe Kingdom of Saudi Arabia commits to reduce carbon emissions by 50% by 2030, a goal envisioned in the strategic framework of Vision 2030. The framework suggests that Saudi Arabia is increasingly investing in alternative energy to reduce over-reliance on conventional fossil fuels. The ambitious roadmap has attracted significant research interest to understand the different variables involved and their role in achieving sustainable future. However, given the recency of renewable energy initiatives in the Kingdom, the current status of policy and strategy dimensions of the energy landscape remains still unclear. This study undertook a systematic literature review of 87 scholarly articles to examine the policies and strategies characterizing renewable energy development in the Kingdom. Emergent themes from the reviewed articles include the pervasiveness of Vision 2030, Renewable Energy Project Development Office (REPDO), and standardized power purchase agreements (PPAs). Saudi Arabia was found to adopt strategies such as public-private partnerships (PPPs), localization of the renewable energy industry, grid integration, and international collaboration to develop renewable energy. The effectiveness of these strategies is evidenced by impacts such as economic diversification, job creation, environmental sustainability and enhanced energy security. However, several challenges and opportunities were also identified. These include regulatory and policy barriers, technological and infrastructure constraints, financial and investment hurdles, and the need for capacity building and local expertise. The study concludes with implications for policy and practice to achieve the full potential of renewable energy development.15 0Item Restricted Diversity on Boards of Directors: Exploring the Benefits and Challenges of Promoting Board Diversity in Corporate Governance(Saudi Digital Library, 2023-11-23) Alqarni, Omar; Mollica, Vivianadissertation on (Diversity on Boards of Directors: Exploring the Benefits and Challenges of Promoting Board Diversity in Corporate Governance)72 0
