Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0051] Wherein, the terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used in the examples of this disclosure and the appended claims, the singular forms "a", "said" and "the" are also intended to include the plural forms unless the context clearly dictates otherwise.

[0052] When calculating SUCI, if the USIM is set to USIM to perform SUCI calculation, and the terminal is set to ME to perform SUCI calculation, it will cause incompatibility between the terminal and the USIM in SUCI calculation, and finally both the terminal and the USIM cannot calculate SUCI, and SUCI generation fails. results, and further...

Abstract

The invention provides a subscription concealed identifier generation method, a terminal, a USIM, electronic equipment and a computer readable storage medium. The method comprises the following steps: when a terminal tries to calculate an SUCI and fails to read an SUCI calculation information basic file, obtaining first information, which is unavailable to the terminal, of the file; according to the first information, generating a first command requiring an USIM to enable the SUCI calculation information basic file to the terminal; sending the first command to the USIM, so that the USIM sets the SUCI calculation information basic file to be available to the terminal based on the first command, and sends setting success information to the terminal after setting succeeds; receiving the setting success information; and reading the SUCI calculation information basic file from the USIM, and calculating the SUCI based on the read SUCI calculation information basic file. According to the technical scheme, the problem that an SUCI cannot be generated normally can be solved, and execution of SUCI calculation is guaranteed.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method for generating a hidden user identifier, a terminal, a USIM, an electronic device, and a computer-readable storage medium. Background technique [0002] While 5G brings high-speed, short-latency, large-connection business experience and more application scenarios, it also has obvious innovations and improvements in many specific technical requirements, and user authentication is one of them. Aiming at the security problems existing in the 4G network authentication, the 5G authentication scheme has been revised and improved. The most typical one is to use the public-private key encryption system to encrypt the IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) to avoid IMSI The clear text transmission and the resulting problem of monitoring and capturing the IMSI in the air. 5G calls the IMSI equivalent to the ...
