Abstract: In various embodiments, a die is provided. The die may include a physical unclonable function circuit configured to provide an output signal, wherein the output signal is dependent on at least one physical characteristic specific to the die; and a self-test circuit integrated with the physical unclonable function circuit on the die, wherein the self-test circuit is configured to provide at least one test input signal to the physical unclonable function circuit and to determine as to whether the output signal provided in response to the at least one test input signal fulfills a predefined criterion.

Abstract: A data message authentication system in a vehicle communication network includes a sequence generator configured to generate a sequence representative of an intra-message pattern; a parsing processor configured to receive a data message, receive the sequence from the sequence generator, select a subset of data segments from the data message based on the intra-message pattern, and output the selected subset of data segments; and a tag generator configured to receive the selected subset of data segments from the parsing processor and generate an authentication code based on the selected subset of data segments, where the authentication code corresponds to the data message.

Abstract: An intermediate servant device connected in a daisy chain configuration with a set of devices is described. The intermediate servant device may be configured to receive, from a previous servant device of the set of servant devices, a request for data, a first response to the request for data, and authentication information for the first response to the request for data. The intermediate servant device may be further configured to generate a second response to the request for data and determine authentication information for the second response based on the authentication information for the first response, the second response, and a key assigned to the intermediate servant device. The intermediate servant device may be further configured to output at least the authentication information for the second response, the first response, and the second response.

Abstract: Various embodiments provide an input/output module, including: at least one input/output port for the input of data; a signature generator that is coupled to the input/output port and is set up to generate a signature for the data from the data; a reference input, wherein the reference input is set up for the application of a reference signature; and a comparator that is coupled to the signature generator and to the reference input, and is set up to output an alarm signal if the signature of the data on the input/output port differs from the reference signature.
