Abstract: An interaction method and an apparatus are provided. The method is applied to an SE disposed in a terminal. The method includes: receiving a service request from a CA (201), where the CA is an application that is installed on the terminal and that runs in an REE; determining a to-be-used TUI identifier (202); sending a TUI call instruction carrying the TUI identifier to a TEE (204), where the TUI call instruction is used to indicate the TEE to obtain a stored TUI template or TUI function module corresponding to the TUI identifier, drawing an image based on the TUI template or the TUI function module (205), and calling a TUI to display the drawn image (206); receiving response information from the TEE (207), where the response information is information entered by a user for the displayed image by using the TUI or information generated by the TEE based on interaction between the user and the image displayed by the TUI (208); and executing a corresponding service procedure based on the response information (209). In this way, service development difficulty can be reduced.

Abstract: In this application, a terminal transaction method and a terminal are provided and used to resolve a problem existing in the prior art that an NFC application does not match a type of a POS, and there is relatively poor user experience. The method includes: establishing, by a terminal, a near field communication NFC radio frequency connection to a point of sale POS, and starting up a first transaction; and selecting, by the terminal, a first NFC application corresponding to the POS, and performing the first transaction when a use condition of the first NFC application is already satisfied.

Abstract: A method includes sending, by a trusted application (TA) entity, a certificate of the TA entity and a private key signature of the TA entity to a target security domain (SD). The certificate and the private key signature enable the target SD to perform trust verification via a server, obtaining, by the TA entity, a first key of the target SD when the trust verification of the TA entity succeeds, and establishing, by the TA entity, a trust relationship with the target SD.
