Abstract
A system for securely transmitting data includes a control device and at least one security module. The control device is configured for producing a cryptographic key using a physically unclonable function (PUF). The at least one security module is configured for communicating with the control device at least one of confidentially and authentically using the cryptographic key. The control device has no storage for storing the cryptographic key. The control device includes at least one hardware device that is configured for providing a specific feature combination. The control device also includes a calculation unit that is configured for producing the cryptographic key using the specific feature combination and the physically unclonable function (PUF). The control device further includes a program-controlled device that is configured for executing a first computer program product, which is configured for performing the encrypted/authenticated communication with the security module via a first and second communication interfaces.
