Abstract

This invention discloses a method for obtaining service keys including: NAF determines services to be initiated to send a push service key request to BSF, which applies the key computation method to compute the obtained push service key based on the obtained push service key and returns it to the NAF to send the push information to UE, which computes to get the push service key. This invention can differentiate the service key initiated actively by NAF and that initiated by UE by altering the computation formula of the service key started up by UE or adding a push service authorization label parameter for the push service key so as to avoid that NAF not ordering the push service uses the service.

Description

Technical field

[0001] The present invention relates to the field of authentication technology, in particular to a method for obtaining a service key applied in a service initiated by a network side. Background technique

[0002] In the third-generation wireless communication standard, the General Authentication Framework (GAA) is a user identity verification structure used by multiple application service entities and provides a key for secure communication for users to access application services. Application services can be multicast / broadcast services, user certificate services, instant information provision services, etc., or agency services.

[0003] Figure 1 is a schematic diagram of the GAA structure. As shown in Figure 1, GAA is usually composed of a user terminal (UE) 101, a guided authentication server entity (BSF) 102 that performs initial check and verification of user identity, a user home server (HSS) 103, and positioning The subscriber entity (SLF) 104 and the netw...
