Abstract
E-learning systems have gained significant attention in recent years, with the demand for secure data transmission among students, instructors, and examiners becoming increasingly crucial. The integration of intelligent devices, data analysis, and cybersecurity into e-learning environments is largely supported by the Internet of Things (IoT). When combined with Fog and Cloud computing, IoT can significantly enhance the performance of latency-sensitive and computing-intensive tasks. This paper presents an IoT-Fog-Cloud framework designed to address the security challenges associated with sharing E-exams, including fine-grained access control and the preservation of security. The proposed framework brings services closer to students, improves the efficiency of E-exam data analysis, and reduces the encryption burden on users' devices by offloading part of the encryption process to fog servers. Additionally, it provides fine-grained access control to E-exam content using various cryptographic techniques. The IoT-Fog-Cloud framework operates by integrating layer components and layer processes. Layer components include Fog Gateway Nodes (FGNs), cloud data centers, and General Fog Nodes (GFNs), while layer processes offer benefits such as reduced latency, enhanced response times, and improved privacy and security preservation. The framework achieves data confidentiality, fine-grained access control, collusion resistance, and unforgeability, ensuring secure procedures within the proposed framework.
