Terminal initiated identity hiding method for mobile communication system subscriber

Abstract

The invention discloses a terminal initiated identity hiding method for a mobile communication system subscriber. The method comprises the steps of dynamically generating a novel legal IMSI or SUPI bya terminal, subjecting a network to information updating, synchronizing and collision elimination by the terminal through using the novel IMSI or SUPI so as to change an identity of the subscriber during communication and decouple the identity of the subscriber and a communication identity. According to the method, only through customizing a USIM / eSIM card of the terminal or subjecting a customizable firmware part in a communication processor to software customization and carrying out a little revision on rear-end HSS or AUSF / UDM / UDR, subscribers or special industries with high security requirements can achieve the effect that a corresponding relationship between the same subscriber and the IMSI or SUPI changes randomly in a manner of not changing mobile communication standard frameworksand standard protocol flows, and the difficulty in tracking of the subscribers or derivation of the subscribers in real spaces by attackers through trapping the IMSI or SUPI is improved.

Description

technical field [0001] The invention relates to a mobile communication system user identity concealment method initiated by a terminal. Background technique [0002] The first phase of the current 5G mobile communication system standard has been determined, but as a complex ecosystem, the 5G network has various types of participants such as infrastructure providers, mobile communication network operators, and virtual operators. It is stored, transmitted and processed in a complex network that interacts with multiple access technologies, multiple devices, and multiple participants, and faces many risks of privacy leakage. [0003] A large number of virtualization technologies are introduced into the 5G network to support various vertical industry applications. While bringing flexibility, it also makes the network security boundary more blurred. In the case of multi-tenant sharing of computing resources, users' private data is more vulnerable to attacks and leaked. Compared ...
