Abstract

The invention discloses a virtual SIM card information storage method and system. The method comprises the steps that a, a security system receives an operation instruction initiated by a user for operation on a virtual SIM card; b, the security system stores data about operation on the virtual SIM card according to the operation instruction to a resource sharing control area; c, a main system reads the data stored by the security system to the resource sharing control area; the security system and the main system are two secure systems isolated by hardware, and the resource sharing control area is arranged between the security system and the main system; the main system only has a reading right on the resource sharing control area without a modification right. In combination with the secure two-system technology, the virtual SIM card technology is more secure and reliable, and the risks that user information in the virtual SIM card is tampered and property is subjected to loss are reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication terminals, in particular to a virtual SIM card information storage method and system. Background technique [0002] The existing virtual SIM card technology generally cooperates with the operator to directly write the virtual SIM card information into the chip ROM, so as to realize automatic selection of different networks across countries for authentication and Internet access. However, our ordinary system is not secure enough, and there is a risk of hijacking and tampering with virtual SIM card information. [0003] How to ensure security while giving customers convenience and cheap traffic is an urgent problem to be solved by virtual SIM card technology. It is not enough to directly store the relevant information of the virtual SIM card in the mobile phone system for security. If the mobile phone is rooted, the information and data of the virtual SIM card may be tampered with or h...
