A data transmission method is described, where first data is transmitted to a first processor, then second data based on the first data is transmitted to a second processor, and a check result is transmitted back to the first processor. This permits an independent check of data transmitted to a first processor by a second processor, so that abuse or prohibited use of first data in the first processor can be prevented.
