Problems solved by technology

However, in actual network deployment, on the one hand, not all operators around the world can implement this, and on the other hand, SIM / USIM cards cannot provide public keys or certificates for operators in all countries and regions.
Therefore, SUPI will still be leaked and the user's location will be tracked

Abstract

The invention relates to the field of communication, and discloses a method and device for realizing SUPI conversion, an identification card and a storage medium. The method comprises at least one SUPI updating process: receiving an authentication request sent by a terminal, wherein the authentication request carries an original SUPI / SUCI; creating an authentication vector AV according to the authentication request, generating a new SUPI, and attaching the new SUPI to the AV to form a new authentication vector AV'; sending the NAS authentication message carrying the AV' to the terminal; and when an authentication success notification is received, updating the user SUPI mapping table to enable the current user and the new SUPI to form a mapping relationship. According to the embodiment of the invention, the conventional unique mapping mode of the user identity and the SUPI is changed, and the SIM / USIM card is used for realizing SUPI conversion, so that the new SUPI is started when the attachment process is started again, the network tracking can be effectively prevented, and the protection strength is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for realizing SUPI conversion, an identification card and a storage medium. Background technique [0002] In the 2G / 3G / 4G mobile network, when the user equipment (UE) registers for the first time, since the UE and the network have not negotiated the air interface key for air interface encryption, the permanent identification of the user, such as: international mobile user The identifier (international mobile subscriber identifier, IMSI) can only be transmitted in clear text over the air interface. However, the IMSI is transmitted in clear text over the air interface, which may easily lead to the interception of the user's IMSI information, thereby causing the user's information (such as location information) to be leaked. [0003] In the 5G mobile communication network, use Network Function Virtualization (Network Function Virtualization, NFV) / Software...
