IoT trust management

Introduction

The Internet of Things (IoT) integrates physical objects into information networks to provide advanced services. Trust management is crucial in IoT for ensuring reliable data fusion, qualified services, and enhanced security. This synthesis explores various trust management approaches in IoT, highlighting key insights from multiple research papers.

Key Insights

Hierarchical and Scalable Trust Management:
- Hierarchical trust-based service management protocols, such as IoT-HiTrust, achieve scalability and accuracy in large-scale mobile cloud IoT systems, outperforming contemporary protocols.
- Trust2Vec manages trust relationships in large-scale IoT systems and mitigates large-scale trust attacks using network embeddings.
Trust Management Architectures:
- IoTrust integrates Soft Defined Network (SDN) in IoT and uses cross-layer authorization protocols for efficient trust management.
- A formal trust management control mechanism based on architecture modeling of IoT decomposes IoT into sensor, core, and application layers, each managed by trust mechanisms for specific purposes.
Energy-Efficient Trust Management:
- Trust management mechanisms adapted to the IEEE 802.15.4 protocol can significantly reduce the active listening time of IoT nodes, making them more energy-efficient.
Service-Oriented and Adaptive Trust Management:
- Adaptive and scalable trust management techniques support service composition in SOA-based IoT systems, using distributed collaborative filtering to minimize convergence time and trust estimation bias.
Reputation and Behavior-Based Trust Evaluation:
- Behavior-based Reputation Evaluation Scheme (BES) and Organization Reputation Evaluation Scheme (ORES) provide efficient trust establishment in IoT by evaluating node behaviors and organizational reputations.
- Trust management systems use local and global perceptions to measure trust, aiding in decision-making tasks like secure routing and device authentication.
Blockchain-Based Trust Management:
- A hierarchical and scalable blockchain-based trust management protocol supports mobility and resilience against malicious attacks, enhancing trust evaluation in distributed IoT systems.

Conclusion

Trust management in IoT is essential for ensuring reliable and secure operations. Various approaches, including hierarchical protocols, architecture-based mechanisms, energy-efficient adaptations, service-oriented techniques, reputation-based evaluations, and blockchain integration, contribute to effective trust management. These methods collectively enhance scalability, accuracy, energy efficiency, and resilience against attacks, paving the way for trustworthy IoT systems.
