The Construction and Dynamic Maintenance Mechanism of Trusted Groups in Edge Computing

Aiming at the problem of lack of an edge computing-oriented Internet of Things (IoT) node group management mechanism. Based on the trusted model of multi-dimensional attributes, this paper designs a trusted group construction mechanism considering the commonalities and differences of node trusted characteristics. Further resist the attack behavior of malicious nodes and ensure the trusted operation of edge computing. In addition, the malicious feedback behavior of nodes and the impact of system dynamic changes. A dynamic maintenance mechanism (DMM) is proposed for the trusted group, and the reward mechanism is used to encourage collaboration between nodes to further maintain the validity and reliability of the trusted group.
