Abstract
Methods and systems for processing secure information are disclosed. One method includes receiving secure data from a user via an input device. The method also includes routing the secure data to a secure processor using a hardware multiplexer. The method also includes processing the secure data using the secure processor. The method also includes receiving non-secure data from the user via the input device. The method also includes routing the non-secure data to a second processor using the hardware multiplexer. The method also includes processing the non-secure data using the second processor. The method also includes altering a routing state of the hardware multiplexer using the secure processor. The routing state of the hardware multiplexer is only controlled by the secure processor.
