Abstract
An interaction method includes receiving a service request from a client application (CA) installed on a terminal and that runs in a rich execution environment (REE), determining a trusted user interface (TUI) identifier, sending a TUI call instruction carrying the TUI identifier to a trusted execution environment (TEE) to instruct to draw an image based on the TUI template or the TUI function component to call a TUI to display the drawn image, receiving response information from the TEE, and executing a corresponding service procedure based on the response information.
