    摘要： A method of trusted data communication. The method comprises executing a data communication application in a trusted security zone of a processor, wherein the processor is a component of a computer, commanding a controller of a peripheral device to execute a control application in a trusted security zone of the controller, wherein the controller is a component of the computer, commanding at least one of another peripheral device or a user interface device to not access a data bus of the computer, verifying that the controller is executing the control application in the trusted security zone of the controller, sending data from the processor to the controller over the data bus of the computer, and the controller one of transmitting the data sent by the processor on an external communication link, reading a memory storage disk, or writing to a memory storage disk.
