Abstract
A method identifies a manipulation of an analog signal by means of a control device of a vehicle. A series of messages are received from a bus system using the control device of the vehicle, wherein a message of the sequence of messages includes a value of the analog signal. The method includes storing the sequence of messages in a buffer of the control device, and determining a temporal profile of the analog signal based on the stored sequence of messages. The method further includes calculating a gradient for the determined temporal profile of the analog signal, and plausibility-checking the calculated gradient to identify the manipulation of the analog signal. The method also includes providing an alarm message if the gradient is not plausible.
