A method for writing an esim number, a security system, an esim number server and a terminal

Abstract

The embodiment of the present invention discloses a method for writing an ESIM number, which is used to improve the security of writing the ESIM number and avoid risks such as malicious hijacking or tampering of the ESIM number. The method in the embodiment of the present invention includes: the security system receives the ESIM number writing instruction; if the security system inquires that the ESIM number writing instruction matches the white list of the ESIM number server, the security system sends the ESIM number writing instruction through the virtual private network VPN according to the ESIM number writing instruction. The corresponding ESIM number server sends an ESIM number writing request; the security system receives the encrypted ESIM number data sent by the ESIM number server based on the ESIM number writing request; the security system decrypts the encrypted ESIM number data; the security system decrypts the decrypted ESIM number data Write to ESIM device. The embodiment of the present invention also provides a security system, an ESIM number server and a terminal, which can effectively avoid possible risks in each link of ESIM number writing and improve the security of the ESIM number.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for writing an ESIM number, a security system and a terminal. Background technique [0002] A SIM card (Subscriber Identity Module, customer identification module), also called a smart card, in a communication network, a SIM card is not only a subscriber identity card, but also a service carrier. The ESIM card is an embedded SIM card that can integrate the SIM card information into the device chip. Compared with the traditional SIM card, the ESIM card is similar to a virtual SIM card. If the device uses the ESIM card, the user no longer needs to buy it After installing the device, you can insert the card yourself, but you can directly use software registration or direct purchase to select the operator network and package. However, the logic of the ESIM card and the SIM card is the same, but it has changed from external to internal, and there is no improvement in security. [...

AI Technical Summary

Problems solved by technology

From the above process, it can be seen that the writing method of the ESIM number has the following problems: 1. The connection to the network is initiated by the ordinary system, and the transmission security is not guaranteed; 2. The ESIM number data information is written into the ESIM chip device by the ordinary system, and the data has been Risk of hijacking and tampering; 3. There is no whitelist mechanism established for mobile terminals, there may be interference with illegal servers, and there is a risk of malicious writing
