Abstract

A method for producing a hardware device, in particular a trusted platform module for the execution of at least one cryptographic algorithm, the hardware device corresponding to a real-time class, i.e., it fulfils specifiable run-time requirements for real-time applications, wherein the method comprises preparing at least one cryptographic algorithm in the manner of a program code; determining a maximum/longest execution time (WCET) for the algorithm, producing a tamper-proof hardware module, which is configured to execute the algorithm, and assigning the hardware module to a real-time class depending on the maximum/longest execution time (WCET).

First claim

The invention claimed is:

1. A method for producing a hardware device for executing at least one algorithm, wherein the hardware device corresponds to a realtime class, comprising:
providing at least one algorithm in the style of a program code, the at least one algorithm having a prescribed maximum data length for an input parameter and being executed based on the at least one input parameter;
determining a maximum execution time for the algorithm;
fabricating a tamper-proof…
