Abstract: The present disclosure provides a method for preparing a superhydrophobic surface of an aluminum alloy through laser peening, including the following steps: coating a surface of the aluminum alloy as an absorption layer with an organic component-containing confinement layer to obtain a coated aluminum alloy, where the organic component-containing confinement layer is a mixed organic solution including 5 mL to 10 mL of perfluorooctyltriethoxysilane (FOTS), 100 mL to 200 mL of absolute ethanol, and 30 mL to 50 mL of distilled water; and subjecting a surface of the coated aluminum alloy to the laser peening to form the superhydrophobic surface.

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.
