US 2025/0097015 A1 · Communication Authentication Method and Related Device

Abstract

communication authentication method and a related device, the method including sending, by a user terminal, a generic bootstrapping architecture (GBA) authentication request carrying a user terminal identifier, receiving, by the user terminal, an authentication request carrying an authentication token (AUTN) and a random number (RAND), and deriving, by the user terminal, a first authentication vector based on the AUTN and the RAND, where the first authentication vector is different from a second authentication vector of the user terminal, the first authentication vector is a 5th generation (5G) GBA authentication vector, and the second authentication vector includes at least one of a 3rd generation/4th generation (3G/4G) GBA authentication vector or a 5G authentication vector.

Dependent claims

A method, comprising:

receiving, by a unified data management entity, an authentication request carrying a user terminal identifier;
determining, by the unified data management entity, that the authentication request is a generic bootstrapping architecture (GBA) authentication request based on a dedicated authentication request message name or type of the authentication request;
generating, by the unified data management entity, a first authentication vector of a user terminal represented by the user terminal identifier, wherein the first authentication vector is different from a second authentication vector of the user terminal, the first authentication vector is a GBA authentication vector, and the second authentication vector is an authentication vector;
and
sending, by the unified data management entity, a GBA authentication response carrying the first authentication vector.

2 more elements

An apparatus, comprising:

at least one processor;
and
a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the apparatus to perform operations comprising:
receiving an authentication request carrying a user terminal identifier;
determining that the authentication request is a generic bootstrapping architecture (GBA) authentication request based on a dedicated authentication request message name or type of the authentication request;
generating a first authentication vector of a user terminal represented by the user terminal identifier, wherein the first authentication vector is different from a second authentication vector of the user terminal, the first authentication vector is a GBA authentication vector, and the second authentication vector is an authentication vector;
and
sending a GBA authentication response carrying the first authentication vector.

5 more elements

An apparatus, comprising:

at least one processor;
and
a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the apparatus to perform operations comprising:
sending an authentication request carrying a user terminal identifier, wherein the authentication request is with a dedicated authentication request message name or type indicating that the authentication request is an authentication request for generic bootstrapping architecture (GBA) authentication;
and
receiving a GBA authentication response carrying a first authentication vector of a user terminal represented by the user terminal identifier, wherein the first authentication vector is different from a second authentication vector of the user terminal, the first authentication vector is a GBA authentication vector, and the second authentication vector is an authentication vector.
