A consensus mechanism for indirect trust assessment is introduced in this paper. The specific consensus process is shown in Figure 2. Each round of the consensus process includes 3 stages: node division, consensus process, and consensus verification. Before the first round, the list of consensus nodes that can participate in the consensus needs to be filtered. The consensus nodes will send the feedback trust value to the master node to trigger the trust aggregation and verification mechanism. Till the end of consensus, the nodes participating in this round of consensus will be updated with reputation, and malicious nodes will be replaced to guarantee the security of the next round of consensus. |
