Embodiment 1

[0033] reference image 3 with Figure 4 In this embodiment, a method for implementing SIM card data security protection by using an embedded secure element (eSE) includes: using an embedded secure element (eSE) to divide the SIM application into a security-related part and a non-security-related part. A virtualized SIM card; a modem (Modem) uses the virtualized SIM card to interact with the network side through an air interface according to instructions from the application processor (AP); sends the instructions originally sent to the physical SIM card to the application processor (AP) ; The application processor (AP) performs security protection processing and non-security protection processing respectively according to the security attributes of the instructions.

[0034] reference Figure 5 , Further, security protection processing includes: security data personalization processing and security data use processing.

Abstract

The invention provides a method utilizing an embedded safety element to realize safety protection for SIM card data. According to the method, an SIM application is divided through employing the embedded safety element into a safety related portion and a non-safety related portion to realize an virtual SIM card; the virtual SIM card is utilized by a modem according to an instruction of an application processor to interact with a network side through an air interface; an instruction supposed to be sent to a physical SIM card is sent to the application processor; safety protection processing and non-safety protection processing are carried out by the application processor according to safety attributes of the instruction. The method is advantaged in that the embedded safety element (eSE) is taken as a storage and calculation entity of a safety function, on one hand, safety protection for the SIM card data is realized, on the other hand, functions of the non-safety related portion can be processed through utilizing application processor software, and performance and flexibility are relatively improved.

Description

Technical field [0001] The invention relates to the technical field of mobile communication terminals and Internet of Things communication terminals, in particular to a method for realizing SIM card data safety protection by using embedded safety elements. Background technique [0002] SIM card (Subscriber Identification Module) is also called subscriber identification card or smart card. Mobile communication terminals and IoT communication terminals must be installed with this card before they can be used. The SIM chip stores user identification, encryption key, phone book and other content, which can be used for the network to authenticate the customer's identity and encrypt the communication process. Such as figure 1 As shown, the physical SIM card is an independent security entity. The disadvantage of the physical SIM card is that it takes up physical space and the replacement process is complicated. [0003] In addition to the aforementioned physical SIM cards, there is also ...
