A Dynamic Tree Topology-based Method for Secure Transmission of Ciphertext Data in the Cloud for the Internet of Things for Electric Power

Due to the lack of rationality of channel resource allocation in the transmission phase, the effect of transmission has certain limitations, therefore, a study on the secure transmission of ciphertext data in the cloud of power Internet of Things (IoT) based on the dynamic tree topology is proposed. When planning the channel resources in the secure transmission of ciphertext data in the cloud of electric power Internet of Things using the frame slot allocation algorithm in the dynamic tree topology, the parent-child relationship in the tree topology subdivides a single superframe into multiple frames and further divides each frame into three independent time slots, and avoiding the time slot conflict within the vertical distance of two hops from the perspective of improving the overall efficiency of the network; Ciphertext transmission is realized under the distributed consensus mechanism. In the test results, the data transmission completion effect is always stabilized above 0.975, and the energy consumption is always lower than that of the control group.
