The application discloses a method for establishing end-to-end secure communication of unmanned aerial vehicle under cloud network architecture, and takes cloud server as a security service center to provide full-process authentication service for unmanned aerial vehicle end system; the cloud server only issues public authentication materials to unmanned aerial vehicles, and session key negotiation and establishment of end-to-end secure communication are realized between unmanned aerial vehicles; the unmanned aerial vehicle end system does not need to store authentication materials of other unmanned aerial vehicles in advance, the cloud server is driven by specific tasks, and specific authentication materials required for key negotiation are issued to unmanned aerial vehicles which need to be securely cooperated according to task requirements. The application only requires that the cloud server and any one of the unmanned aerial vehicles for key negotiation establish a communication connection, and the authentication materials issued by the cloud server can make the unmanned aerial vehicles realize key negotiation and establish an end-to-end secure channel in a specific range; different temporary public keys are used for each request message, which can effectively prevent the harm caused by long-term and short-term secret leakage.

This utility model discloses a waste gas treatment device for the production of ferrite cores, relating to the field of waste gas treatment device design technology. It includes a fixed support plate, an impurity adsorption unit, and a waste gas purification body. A stable support leg is fixedly connected to each of the four corners of the lower surface of the fixed support plate. An impurity adsorption unit is provided on the upper surface of the fixed support plate, and the four corners of the fixed support plate are chamfered. The waste gas purification body includes a waste gas purification tower, a partition plate, a spray head, a water pump, a limiting plate, and a purification filter element. A waste gas purification tower is fixedly connected to the upper surface of the fixed support plate at the right side of the impurity adsorption unit. This device can treat the waste gas generated during the production of ferrite cores, preventing environmental pollution and minimizing harm to humans. The filter element is also easy to replace.
