Abstract

A device for carrying out a cryptographic method has an input interface for receiving input data, an output interface for outputting output data, and a cryptographic unit for carrying out the cryptographic method. A first functional unit is provided which is designed to convert at least a portion of the input data into transformed input data using a first deterministic method, and to supply the transformed input data to the cryptographic unit, and/or a second functional unit is provided which is designed to convert at least a portion of output data of the cryptographic unit into transformed output data using a second deterministic method, and to supply the transformed output data to the output interface.

First claim

What is claimed is:

1. A hardware device, comprising:
an electronic input interface;
an electronic output interface; and
cryptographic processing circuitry;
wherein the device is configured to:
convert at least a portion of binary digit input data received via the electronic input interface into transformed input data using a first deterministic method to ensure a first digital decorrelation, the first digital decorrelation being of the binary digit input data with respect…
