Problems solved by technology

[0005] (1) For some applications with consistent business scenarios, the functions implemented by these multiple TAs are completely consistent, which will inevitably cause waste of TEE resource space;
[0006] (2) For application developers, repeated development of TA is required every time, which reduces the development efficiency of trusted applications

Abstract

The invention relates to a user terminal, comprising: a multimedia execution environment configured to: set at least one client application program; A trusted execution environment is configured to include a sharing management module for selecting a corresponding trusted application template based on a trusted service request of a client application and loading corresponding characteristic data based on a personalized request from the client application to generate a trusted application instance in response to the trusted service request; Wherein each trusted application template corresponds to a set of client applications belonging to the same class. It can realize the full use of system resources, avoid the waste of TEE resource space, and improve the development efficiency of trusted applications.

Description

technical field [0001] The present invention relates to the technical field of trusted applications, and more specifically, to a user terminal and a trusted application management system. Background technique [0002] With the rapid development of e-commerce and mobile payment, the demand for security applications is also increasing. Developers of security applications need to develop specific client applications (Client Application, CA for short) and trusted applications (Trusted Application, TA for short) according to their actual needs. CA runs in REE (Multimedia Execution Environment), and TA runs in TEE (Trusted Execution Environment). CA is generally responsible for completing the external interface at the user space level of Rich OS and the function of sending commands (CMD) to TA, and TA according to The CMD sent by the CA implements specific security functions (such as enabling the TUI, securely processing and saving data, encrypting and decrypting data, etc.). ...
