Abstract

The embodiment of the invention provides a building method and a building device for a root security domain, and a terminal. The method comprises the steps of acquiring user information of an application currently needing to be used by a user; sending the user information to a service provider corresponding to the application; acquiring individual information corresponding to the user informationand returned by the service provider; and building the root security domain in the terminal with a trusted execution environment (TEE) module, and writing the individual information into the root security domain. According to the scheme of the invention, the dynamic root security domain is built for the application and the individual data of the user is written in according to user needs during the using process of the user.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a creation method, device and terminal based on a security domain. Background technique [0002] Trusted Execution Environment TEE (Trusted Execution Environment) refers to an independent secure operating environment based on a security chip in a mobile terminal, which can be regarded as a miniature operating system. TEE is logically isolated from the normal application operating environment REE (Rich Execution Environment) (such as the Android environment), and can only interact through authorized APIs. TEE can provide high-reliability security services to common applications in REE, such as secure input, secure storage, data encryption, etc. These security features require the application service provider SP (Service Provider) to establish a root security domain rSD (Root Security Domain) in the security terminal, and preset relevant keys in it, or dynamically ...
