Abstract

A trusted user interface display method and system, for use in an electronic device using both a secure operating system (10) and a mobile operating system (20). The method comprises: a) before display, sending interface data to be displayed from a mobile operating system (20) to a secure operating system (10); b) said secure operating system (10) receiving the interface data to be displayed from the mobile operating system (20), and processing said interface data; c) sending said processed interface data to be displayed to the display component of an electronic device (30) for display.

Description

technical field [0001] The present invention relates to the field of intelligent mobile terminals, and more specifically, relates to technologies related to trusted user interface display. Background technique [0002] TEE (Trusted Execution Environment, Trusted Execution Environment) is a solution proposed to solve the security risks existing in current mobile smart terminals. TEE constructs a safe operating environment isolated from mobile smart terminal operating systems (such as Android, IOS, windows phone, etc.). TEE is located in the security area of ​​the main processor of the mobile smart terminal, which can ensure the storage, processing and protection of sensitive data in a trusted environment. TEE provides a secure execution environment for authorized security software (trusted software), enabling end-to-end security through execution protection, confidentiality, integrity, and data access rights. [0003] In other words, the smart terminal using TEE runs two op...
