US 2017/0317982 A1 · ELECTRONIC DEVICE WITH AN OPERATIONAL UNIT

Abstract

An electronic device has an operational unit for communication. The operational unit is provided with a first interface unit for secure communication and a second interface unit for insecure communication. To provide electronic devices, in which the manipulation of information that is transmitted via the first interface unit is made at least more difficult, the operational unit is separated into a secure operational block and an insecure operation block and has only a first transmitter unit, the first interface unit being arranged in the secure operational block and the second interface unit being arranged in the insecure operational block, and the first transmitter unit is designed for transmitting first signals only from the secure operational block via a first signal path to the insecure operational block.
