Abstract: A network may authenticate a user equipment (UE) to access an edge data network. The network generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network corresponding to the network component, receives an identifier associated with the first credential from a further network component in response to the UE transmitting an application registration request to a server associated with an edge data network and retrieves the first credential based on the identifier. The network also receives a multi-access edge computing (MEC) authorization parameter, verifies the MEC authorization parameter and transmits an authentication verification response to a second network component.

Abstract: A graft copolymer and a preparation method and use thereof. The method for preparing a graft copolymer includes: dissolving an N-ethyl-2-pyrrolidinone-substituted flavan-3-ol (EPSF) and a starch in a polar organic solvent, to obtain a raw material solution; and mixing the raw material solution with ascorbic acid and hydrogen peroxide to obtain a mixture, and subjecting the mixture to a grafting reaction, to obtain the graft copolymer.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for secured user equipment communications over a user equipment relay. In some embodiments, symmetric or asymmetric encryption may be used for the secured user equipment communications.

Abstract: A device for double-sided processing through single shot peening includes: a shot peening system, a workpiece clamping mechanism for clamping a workpiece, and a rebound system. The workpiece is provided with a first through-hole, and the first through-hole directly faces a nozzle. The rebound system includes a reflecting surface, an open container, and a reflecting surface gripping unit. The reflecting surface includes an upper reflecting surface, a middle reflecting surface, and a lower reflecting surface. The middle reflecting surface is provided with a second through-hole. The upper reflecting surface and the lower reflecting surface are both made of flexible elastic materials and are both provided with waterproof layers. A partition plate is disposed in the open container and partitions the open container into a first cavity and a second cavity. The second cavity is provided with a filling liquid, and the partition plate is slidable in the open container.
