Abstract

A method for authenticating a message transmitted via a communication channel, including the following: sampling recurring signal edges within a data frame of the message, sampling values being obtained with a start time that is offset between the signal edges, reconstructing an average signal characteristic of a part of the message from the sampling values, calculating signal-technical properties of the data frame from the signal characteristic, and the message is authenticated based on the properties.
