Data processing method and device based on 5G core network

Abstract

The embodiment of the invention provides a data processing method and device based on a 5G core network. The method comprises the steps that a DSEF receives a processing instruction; when the processing instruction is a safety parameter acquisition instruction, the DSEF generates a safety parameter, and the 5G core network executes an authentication operation, a signaling encryption operation, a signaling decryption operation and a signaling integrity protection operation based on the safety parameter; when the processing instruction is a safety parameter comparison instruction, the DSEF generates a safety parameter comparison result, and the 5G core network executes authentication operation based on the safety parameter comparison result; when the processing instruction is a signaling processing instruction, the DSEF generates a processed signaling, and the 5G core network communicates with the terminal based on the processed signaling; and when the processing instruction is an integrity protection instruction, the DSEF generates an MAC check code, and the 5G core network performs integrity protection of communication with the terminal based on the MAC check code. According to the embodiment of the invention, the special safety equipment generates the safety parameter, compares the authentication parameter and the MAC check code, and encrypts and decrypts the NAS signaling.

Description

technical field [0001] The present application relates to the field of communications, in particular to a data processing method and device based on a 5G (5th generation mobile networks, fifth generation mobile communication technology) core network. Background technique [0002] The 5G core network implements two-way authentication between the terminal UE (User Experience) and the network through network functions, user plane data encryption, integrity protection, signaling encryption, and integrity protection. [0003] In practical applications, for some terminal UEs with special needs, it is necessary to provide services with a higher security level based on the operator's network infrastructure, and the existing 3GPP (3rd Generation Partnership Project, third generation cooperation project) R15 (Release 15, Under the 15th edition) standard, the 5G core network only uses network functions for security verification, and cannot use higher security level services in authenti...
