Registration method of 5G user terminal, user terminal equipment and medium

Abstract

The embodiment of the invention provides a registration method of a 5G user terminal, user terminal equipment and a medium, and the method comprises the steps of enabling the 5G user terminal equipment to send a registration application to a temporary identity registration server in a block chain, wherein the registration application comprises a first public key corresponding to a temporary identity generated by the equipment; receiving block information returned by the temporary identity registration server, and performing hash value verification on the block chain and blocks in the block chain according to the block information; when the verification is passed, searching for a public key of the target operator from the block information returned by the temporary identity registration server according to the identifier of the target operator; and according to a preset encryption algorithm, encrypting a second public key of the target operator by adopting the public key of the target operator and the first public key, and sending encrypted data obtained by encryption to a temporary identity registration server for identity registration. According to the scheme provided by the embodiment of the invention, the data security and confidentiality of the 5G user terminal equipment during identity registration 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...
