FogTrust: Fog-Integrated Multi-Leveled Trust Management Mechanism for Internet of Things

The Internet of Things (IoT) is widely used to reduce human dependence. It a network interconnected smart devices with internet connectivity that can send and receive data. However, the rapid growth IoT has raised security privacy concerns, identification removal compromised malicious nodes being major challenge. To overcome this, lightweight trust management mechanism called FogTrust proposed. multi-layer architecture includes edge nodes, trusted agent, fog layer. agent acts as an intermediary authority, communicating both layer for computation. This reduces burden on ensures trustworthy environment. calculates degree transmits it layer, which uses encryption maintain integrity. encrypted value shared aggregation improve degree’s accuracy. performance approach was evaluated against various potential attacks, including On-off, Good-mouthing, Bad-mouthing. simulation results demonstrate effectively assigns low degrees in different scenarios, even varying percentages network.
