We propose a new way of authentication for components. Traditionally, hard-toreproduce patterns like security holograms are attached or inserted into the component for authentication. During the verification, a-priori knowledge is needed. The approach we follow is that this information should also be attached to the component as digital data signed by cryptographically means. Inside the Collaborative Research Center CRC 653, we research gentelligent components, which are components that enable to inherently store digital information as well as an analog fingerprint. Using these components, we enable authentication with virtually no a-priori knowledge.
