Abstract: A transmitter device of a bus-based communication system may add one or more padding bits, associated with providing traffic flow confidentiality for communication of a payload on a communication bus, either to the payload on a transport layer, or to one or more first frames on a data link layer. The one or more first frames may include a transport layer payload associated with the payload. The transmitter device may transmit one or more second frames, including a data link layer payload associated with the one or more first frames, on the communication bus. A receiver device of the bus-based communication system may receive the one or more second frames on the communication bus. The receiver device may process the one or more padding bits from either the one or more first frames on the data link layer, or from the payload on the transport layer.

Abstract: A device, method, or computer program product for conducting a cryptographic operation in a vehicle is disclosed herein. The device is arranged to receive key data and input data, and to conduct a cryptographic computation of the input data to output data using the key data. The cryptographic computation is conducted with or without side channel attack counter measures, which are toggled based on the key data or based on a control input.

Abstract: A communication device is described including a receiver configured to receive a message including message data and a message authentication code, a first register for storing a received message authentication code and a second register for storing a computed message authentication code. The device also includes a first processor configured to extract the message authentication code from the message and to store the message authentication code in the first register, a second processor configured to compute a message authentication code based on the message data and to store the computed message authentication code in the second register, and a comparing circuit configured to compare the contents of the first register and the second register and to provide a comparison result.
