Problems solved by technology

[0002] In the standard 5G registration process, a SIM card is inserted into the 5G user terminal equipment (referred to as UE), and the SIM card has the operator's public key, or the shared key between the 5G UE and the operator, and any middleman cannot modify the SIM card The built-in public key prevents man-in-the-middle attacks. However, in the no-SIM card access solution, when a 5G UE without a SIM card submits its own public key, a malicious middleman or listener can easily replace the public key. Operators are also unaware, so all confidential communications between 5G UEs and operators may be monitored

Abstract

The embodiment of the invention provides a registration method of a 5G user terminal, user terminal equipment and a medium. A third public key of a target operator, a block number of a block includingthe third public key and information of an adjacent node of the 5G user terminal equipment on the Internet are acquired from a temporary identity registration server, the block content correspondingto the block number is obtained from the adjacent node, and the third public key fed back by the temporary identity registration server is verified through the obtained block content, so that the third public key is prevented from being tampered or replaced, and the data security and confidentiality in the 5G UE registration process are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of blockchain, and in particular, to a registration method of a 5G user terminal, user terminal equipment and a medium. Background technique [0002] In the standard 5G registration process, a SIM card is inserted into the 5G user terminal equipment (referred to as UE), and the SIM card has the operator's public key, or the shared key between the 5G UE and the operator, and any middleman cannot modify the SIM card The built-in public key prevents man-in-the-middle attacks. However, in the no-SIM card access solution, when a 5G UE without a SIM card submits its own public key, a malicious middleman or listener can easily replace the public key. Operators are also unable to perceive, so all confidential communications between 5G UEs and operators may be monitored. Contents of the invention [0003] Embodiments of the present invention provide a registration method for a 5G user ter...
