Abstract:
A control device is connected to at least one encryption/decryption device via at least one communication device. The control device is connected to a round key generator via at least one further communication device. The control device has at least one external key input, the at least one encryption/decryption device has at least one external data input and at least one external data output, and the at least one encryption/decryption device and the round key generator are decoupled from one another.
