Electric power 5G network slice authentication message matching method and device based on edge calculation

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.
