Embodiment approach

[0072] As a possible implementation, the identity management entity may also include:

[0073] The verification unit 504 is configured to verify whether the certificate request message received by the receiving unit 501 is a legal message, and when the verification unit 504 verifies that the certificate request message is a legal message, trigger the generation unit 502 to generate a digital certificate for TE.

[0074] As a possible implementation, the certificate request message carries the TE's identity, encrypted identity signature, and encrypted signature public key;

[0075] Verification unit 504 may include:

[0076] The first decryption subunit 5041 is configured to use a symmetric key to decrypt the encrypted identity signature received by the receiving unit 501 and the encrypted signature public key to obtain the identity signature and signature public key of the TE. The symmetric key is managed by the identity Entity-determined secret key used to establish NAS comm...

Abstract

Disclosed are an authentication method, related device and system, the method being applied to an identity management entity, the identity management entity being deployed in a core network control plane of an LTE network, the method comprising: receiving a certificate request message from a terminal device; generating a digital certificate for the terminal device; and sending an identity requestmessage carrying the digital certificate to an identity agent entity, the identity agent entity being deployed in a blockchain network, the identity request message being used for acquiring a blockchain identity for the terminal device. By implementing the embodiment of the invention, the access authentication processes of the LTE network and the blockchain network can be fused.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to an authentication method, related equipment and a system. Background technique [0002] A terminal equipment (Terminal Equipment, TE) is an indispensable electronic product in people's daily life. Therefore, in order to facilitate people's life, the geographical location of the TE is not fixed, but changes according to needs. However, when the geographic location of the TE changes, it may cause the service network of the TE to switch from a Long Term Evolution (LTE) network to a blockchain network. Since the communication protocol of the LTE network is different from the communication protocol of the blockchain network, in order to ensure the rapid switching of TE from the LTE network to the blockchain network, the access authentication process of integrating the LTE network and the blockchain network has become an urgent need.
