Abstract
A secure interaction method includes receiving, by a processor, a secure processing request sent by an application program, where the application program operates in a normal mode, and the processor operates in the normal mode when receiving the secure processing request, switching, by the processor, from the normal mode to a secure mode according to the secure processing request, reading, by the processor operating in the secure mode, data information into a memory operating in the secure mode, where the data information is data that the processor operating in the secure mode generates after parsing the secure processing request, and controlling, by the processor operating in the secure mode, an accessed device to operate according to the data information stored in the memory operating in the secure mode.
