Title: METHOD FOR IMPLEMENTING HOST CARD EMULATION, TERMINAL, AND DATA ROUTING METHOD AND APPARATUS
Abstract:
Provided in the embodiments of the present invention are a method and an apparatus for implementing host card emulation; a terminal in the present invention, on the basis of the type of an HCE application, installs the HCE application in a terminal environment corresponding to the HCE application type, said terminal environments comprising the trusted execution environment TEE and the rich execution environment REE; the terminal parses a first identifier of the HCE application and at least one second identifier contained in the HCE application, the first identifier being used for uniquely identifying the HCE application in the terminal, and the second identifier being used for identifying a message flow between a card reader device and the HCE application; and the terminal registers the routing information of the HCE application in the TEE, the routing information comprising the first identifier, at least one second identifier, and the terminal environment in which the HCE application is installed. By means of the present invention, an HCE application supporting the two different security levels of TEE and REE can be implemented on a terminal.
