Abstract

The rapid growth of the Internet of Things (IoT) has introduced significant security challenges due to the increasing interconnectivity of devices and the sensitive nature of the data exchanged. Securing IoT communications is crucial to prevent unauthorized access, data breaches, and cyberattacks. However, traditional cryptographic methods often fail to meet the unique needs of IoT systems, which are constrained by resource limitations such as processing power and energy consumption. This research aims to develop a comprehensive information security framework that integrates cryptographic protocols tailored to secure IoT communications while maintaining efficiency. The study employs a mixed-methods approach, combining simulation-based experiments and expert interviews. Various cryptographic techniques, including AES, RSA, and Elliptic Curve Cryptography (ECC), are evaluated in IoT network configurations across different environments. Performance metrics such as encryption time, energy consumption, and data integrity are measured to assess the framework’s effectiveness. The results demonstrate that ECC offers the best balance between security and resource consumption, outperforming AES and RSA in terms of efficiency. Expert feedback confirms the feasibility and scalability of the proposed framework. This research contributes to the field by offering a novel approach to IoT security that can be applied to real-world networks, ensuring secure and efficient communication.

Abstract

The rapid growth of cloud computing, large-scale data centers, and heterogeneous network traffic has exposed structural limitations in traditional distributed routing architectures. Conventional switching and routing mechanisms often lack global network visibility, resulting in suboptimal path selection, inefficient bandwidth utilization, and delayed convergence under dynamic traffic conditions. This study aims to design and evaluate a Software Defined Networking (SDN)-based optimization framework to enhance switching and routing performance through centralized programmability and adaptive traffic engineering. A quantitative experimental design was employed using network emulation across small-, medium-, and large-scale topologies. Comparative analysis was conducted between conventional routing protocols and the proposed SDN-based model. Performance metrics included throughput, end-to-end delay, packet loss rate, convergence time, and bandwidth utilization efficiency. Inferential statistical testing was applied to validate performance differences. Results demonstrate statistically significant improvements under the SDN framework, including increased throughput, reduced latency, lower packet loss, and faster failure recovery. Performance gains were more pronounced in large-scale and high-traffic scenarios, indicating strong scalability and resilience characteristics. The findings confirm that centralized control architecture fundamentally enhances routing optimization and network adaptability. SDN-based approaches provide a scalable and efficient solution for modern programmable network infrastructures.

Abstract

Purpose – This study aims to examine the influence of AI Literacy on students’ Intention to Use Generative AI in learning activities through the mediating role of Perceived Usefulness and the moderating role of AI Anxiety within the higher education context. Design/methods/approach – The study employed a quantitative explanatory approach using a cross-sectional survey design. Data were collected from 250 university students who had prior experience using generative AI for academic purposes. Respondents were selected through purposive sampling based on predefined inclusion criteria. The research instrument consisted of structured questionnaire items measured using a five-point Likert scale. Data analysis was conducted using Structural Equation Modeling–Partial Least Squares (SEM-PLS) to evaluate the measurement model, structural relationships, mediation effect, and moderation effect among variables. Findings – The results indicate that AI Literacy significantly influences both Perceived Usefulness and Intention to Use Generative AI. Perceived Usefulness was also found to positively affect behavioral intention and partially mediate the relationship between AI Literacy and Intention to Use. Furthermore, AI Anxiety negatively moderated the relationship between Perceived Usefulness and Intention to Use, suggesting that psychological concerns toward AI weaken students’ willingness to adopt generative AI despite recognizing its educational benefits. Research implications/limitations – This study contributes to the development of AI-based technology acceptance research by integrating cognitive and psychological factors into a single analytical framework. However, the use of a cross-sectional design and self-reported data may limit the generalizability and causal interpretation of the findings. Originality/value – The originality of this study lies in the integration of AI Literacy, Perceived Usefulness, and AI Anxiety within the Technology Acceptance Model to explain generative AI adoption behavior in higher education learning environments.
