Problems solved by technology

[0004] In the second-level authentication process, the third-party network needs to obtain the user's identity, but the user's identity is usually requested by the operator network from the terminal device and then forwarded to the third-party network. During the process, there is a risk of being leaked

Abstract

The embodiment of the invention provides a secondary authentication method and device, and the method comprises the steps that a core network function entity obtains the identity of first terminal equipment, and the identity of the first terminal equipment is the identity of a first network; and the core network function entity sends the identity identifier of the first terminal device to an authentication device in a second network, the identity identifier of the first terminal device is used for determining an identity identifier of the second network for performing secondary authenticationon a first user, and the identity identifier of the first user is different from the identity identifier of the first terminal device. According to the method, the core network function entity can send the identity identifier of the first terminal device to the authentication device in the second network, and the identity identifier of the first user can be determined through the identity identifier of the first terminal device; the implicit transmission of the identity of the first user can enhance the security protection of the identity of the user in the secondary authentication process.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a method and device for secondary authentication. Background technique [0002] With the rapid development of communication technology, in order to meet the diverse needs of users, many network slices can be deployed in the operator's network to meet the needs of different applications and vertical industries. Before an end device is allowed to access a network or network slice, it needs to perform mutual authentication with the network and / or network slice and be authorized by the network and / or network slice. [0003] At present, the 3rd generation partnership project (3rd generation partnership project, 3GPP) network can support the first-level authentication mechanism and the second-level authentication mechanism at the same time, wherein the first-level authentication mechanism is the authentication between the terminal device and the operator network, an...
