Abstract

The invention discloses a method, a device and a mobile terminal for encapsulating different TEE system interfaces into a standard interface. The method comprises the steps that the interfaces of thedifferent TEE systems are encapsulated targetedly, a TEE unified interface implementation layer calls different TEE system encapsulation interface layers, the call transition from a unified interfaceto the interfaces of the different TEE systems is completed, the access management of multiple applications is provided, and a unified TEE interface SDK is provided for outside; business application achieves a business application function for a TEE system by calling the TEE interface SDK. The TEE system interface encapsulating method, device and the mobile terminal can shield the difference of the access interfaces of the different TEE systems, provide a TEE unified calling interface to facilitate the development and debugging of a business function logic so that the business application canbetter pay attention to the business logic and the development and deployment efficiency is improved, and provide management functions such as concurrent access, mutual exclusion, garbage collection and the like at the TEE unified interface implementation layer.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a TEE system interface encapsulation method, device and mobile terminal. Background technique [0002] As the mobile and consumer market for connected devices matures and grows, security is a growing concern. There is a growing need for security in the use of open environments, especially mobile phones, when using a variety of different "lifestyle" applications. Content protection, corporate applications, connectivity and financial transactions further exacerbate these security concerns, with content owners, service providers, banks, mobile network operators, operating system and application developers, device manufacturers, platform providers and Silicon wafer providers are all important stakeholders in this market. [0003] TEE (Trusted Execution Environment, Trusted Execution Environment) provides the best path to achieve security goals while meeting the needs of impo...
