Abstract

The invention discloses a method for authenticating an NF by an SEPP in a 5G core network. The method comprises the following steps of: when a pSEPP of a service supply side receives a service requestmessage, carrying out legality authentication on a network function cNF of a service consumer side sending the service request message; if the legality authentication is passed, forwarding the service request message to the network function pNF of the corresponding service supply side for service request processing by the security edge protection proxy pSEPP of the service supply end; otherwise,discarding the service request message. According to the method, the legality of the cNF of the service consumer side sending the service request message is authenticated, malicious applications are effectively prevented from being illegally disguised as the cNF of the service consumer side and further transmitting a control plane message to a network function pNF in the service supply side pPLMN,the NF data in the service supply side pPLMN is protected, and the security of the PLMN in the 5G core network is enhanced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for SEPP authentication of NF in a 5G core network. Background technique [0002] In the 5G 3GPP standard, in order to strengthen the internal security of each public land mobile network (hereinafter referred to as PLMN), a security edge protection proxy (hereinafter referred to as SEPP) is added. SEPP is to ensure the security of control plane messages between 5G network functions (hereinafter referred to as NFs) across PLMNs, so as to protect the security of the PLMN network where SEPP is located from external attacks. [0003] In the TS 3GPP 33501-g30 protocol specification, the functions and requirements of SEPP are specified in detail, but the authentication and authorization between SEPP and NF only stay at the network layer and physical layer under the PLMN ID and application layer. Data identification does not authenticate whether the NF subject exi...
