Embodiment Construction

[0103]The embodiment of the application provides an authorization method and device of a service-oriented architecture, which is used to verify the legitimacy of the service request by the network function of the service provider after introducing SCP in the authorization process. Among them, the method and device are based on the same inventive concept. Since the principle of solving problems of the method and device are similar, the implementation of the device and method can refer to each other, and the repetition will not be repeated.

[0104] Some terms involved in the embodiments of the application are explained below for ease of understanding.

[0105] 1) Certificate: refers to a digital certificate, a file containing public key owner information and public key digitally signed by certificate authority (CA), which is used for identity authentication of both communication parties. The certificate includes the certificate version number (version), serial number (serialnumber)...

Abstract

The embodiment of the present application discloses a method and device for service-oriented architecture authorization. The method includes: a first network storage function network element generates a token after receiving a token request, and the first network storage function is included in the token Write the SCP certificate information of the service communication agent, and return the token carrying the certificate information to the sender of the token request; the service provider network function receives the service request, and the service request carries the token containing the SCP certificate information card or carry the token and the verification result of the certificate information; if the service request does not contain the verification result of the certificate information, the service provider network function verifies the certificate information of the SCP; if the verification result is successful Then continue the authorization process. Through the above technical solution, the problem that the network function of the service provider cannot verify the certificate information in the token after the introduction of the service communication proxy can be solved.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a service architecture authorization method. Background technology [0002] The fifth generation (5g) adopts service-based architecture (SBA). The 3rd Generation Partnership Project (3GPP) also proposes the enhancement of service-based architecture (esba). In SBA or esba, all network functions (NF) support transport layer security (TLS). NF allows other authorized NF to access its services. NF Repository Function (NRF) provides management, discovery and authorization services for NF. The service requester NF obtains the token corresponding to the service by requesting authorization from the NRF. The NRF also writes the certificate information of the service requester NF to the token. The service requester NF requests the service from the service provider NF that owns the service according to the token. After receiving the service request sent by the service requester,...
