Method and system for remote initialization of Internet of Things virtual subscriber identity module card

Abstract

The invention provides a method and system for initialization of an Internet of Things virtual subscriber identity module (SIM) card. The method comprises the steps that an Internet of Things terminal is started and has access to the Internet and then sends a connecting request to a terminal certification device according to a preset address; a session key and a corresponding second certification number are generated and sent to a virtual card management device together with a terminal identification after the certification of the Internet of Things terminal is achieved through the terminal certification device, and the address of the virtual card management device, the session key and the corresponding second certification number are encrypted and then fed back to the Internet of Things terminal; the Internet of Things terminal encrypts the terminal identification by means of the session key and sends the terminal identification and the second certification number to the virtual card management device; virtual SIM card data are generated when the virtual card management device certificates the Internet of Things, and the SIM card data are encrypted by means of the session key and then fed back to the Internet of Things terminal. According to the method and system, a complete automatic management scheme is provided for initialization of the Internet of Things virtual SIM card, and safety of the initialization process can be guaranteed.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a remote initialization method and system for a virtual subscriber identification module card of the Internet of Things. Background technique [0002] Compared with conventional handheld mobile devices (such as mobile phones, tablet computers, etc.), the terminal devices of the Internet of Things are different in terms of application purposes, usage scenarios and working environments. Terminal devices in an IoT environment often have the following characteristics: [0003] Harsh working environment: Internet of Things terminal devices often need to work in harsh environments, such as cars in the Internet of Vehicles are often in strong vibration and high temperature environments; [0004] Remote work location: Some IoT terminal devices, such as smart meters, are often deployed in remote areas with few people; [0005] Network connectivity is time-sensitive: The network con...

Problems solved by technology

However, due to the particularity of IoT terminal application scenarios, in many cases (such as in remote areas or in harsh environments), IoT terminals can only be managed remotely, and users cannot perform initialization operations on site. If the virtual SIM card data is saved in the In the Internet of Things terminal, if it is contacted by criminals before the installation of the Internet of Things terminal, it is possible to steal or tamper with the data of the virtual SIM card, so there are unsafe factors

If it is considered to apply for the virtual SIM card data after the IoT terminal is installed in place, the IoT terminal needs to be able to automatically complete the whole process of identity authentication and downloading the virtual SIM card data, and ensure the security of the process; no effective solution
