5G application access authentication method and 5G application access authentication network architecture

Abstract

The invention provides a 5G application access authentication method and a 5G application access authentication network architecture, and belongs to the field of communication security. The method comprises the steps that after a network access attachment request is completed, the electric power 5G system is accessed to an authentication network architecture through a 5G application for secondaryverification. The security authentication protocol interaction process among the electric power 5G terminal, the SMF / UPF and the DNAA server successively verifies network security and identity authentication of the electric power 5G terminal, realizes network and service dual authentication, can establish PDU (Protocol Data Unit) session connection only when 5G application access authentication islegal, otherwise, provides service for the PDU session connection through network rejection, and improves the security of the electric power 5G terminal. The attack surface of a power service domainis reduced, and the problem that a 5G terminal in a current power system has various security defects in 5G network access is solved.

Description

technical field [0001] The present invention relates to the field of communication security, in particular to a 5G application access authentication method and a 5G application access authentication network architecture. Background technique [0002] 5G technology is developing rapidly. In addition to the improvement in data transmission speed, 5G technology has also significantly enhanced security compared with 3G / 4G technology. On the one hand, 5G can provide industry users with end-to-end network connections based on network slicing. On the other hand, the 5G network can allow industry users to customize algorithms and protocols for secondary authentication, that is, user-defined algorithms / protocols can be used for secondary authentication between user terminals and servers. When the power system is maliciously attacked, it will cause very serious problems such as power grid paralysis. Therefore, 5G terminals in the power system have high security technical requirements ...
