Construction and dynamic maintenance method of trusted group in electric power Internet of Things environment

The invention discloses a credible group construction and dynamic maintenance method in an electric power internet of things environment, which is characterized in that a credible group construction and dynamic maintenance mechanism combines credible measurement among nodes to divide the nodes with certain similar credible characteristics into one group based on a credible quantitative result obtained by credible modeling, so that the credible group construction and dynamic maintenance is realized. And meanwhile, a group rule and an individual rule are introduced, so that benefits of most individual nodes are guaranteed, and normal survival and operation of trusted groups in the network are maintained. According to the management scheme, the credible interaction efficiency of the nodes of the power internet of things in power edge calculation is improved, meanwhile, the credible group has certain adaptive capacity to dynamic network changes, and the defense defect of a trust model facing malicious feedback at
