Abstract

The invention discloses an electric power 5G network slice authentication message matching method and device based on edge computing, and the method comprises the steps: carrying out the data interaction between user equipment (UE) and a core network element management module AMF, calculating the Euclidean distance between a slice request feature vector set and each slice supply scheme feature vector provided by the core network element management module AMF through the UE, and carrying out the Euclidean distance between the slice request feature vector set and each slice supply scheme feature vector provided by the core network element management module AMF; and the nearest slice supply scheme is selected as the slice selection of the user. In a slice selection matching process, a random number set C and a random key r are used for hiding feature information of a slice request scheme and a slice supply scheme, so that a third-party attacker is prevented from illegally obtaining slice information, and the security of the feature information of the slice scheme is ensured. Moreover, the deployment scheme is simple, a PKI system is not needed, and through simple arithmetical operation, reduction of data calculation and data transmission overhead is facilitated, transmission delay is reduced, and calculation and communication efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of 5G network slice communication, in particular to a method and device for matching authentication messages of power 5G network slices based on edge computing. Background technique [0002] With the popularization of 5G network communication technology, the application of network slicing is becoming more and more extensive. For example: in smart grid applications, with the rapid development of large-scale distribution network automation, advanced metering, distributed energy access, and user two-way interaction, the communication needs of various power grid equipment, power terminals, and electricity customers have exploded.
