Abstract
In a method of operating an electronic system () a first device () of the electronic system () sends a message to a second device () of the electronic system (). The second device () receives the message, generates a first value utilizing a first function based on at least parts of the history of at least parts of messages previously received at the second device (), and stores the first value in a memory () of the second device (). The first value is comparedwith a second value generated at the first device (), wherein the second value utilizes a second function based on at least parts of the history of at least parts of messages previously sent from the first device () to the second device (). The first and second values are evaluated, and a signal is generated if the evaluating of the first and second values indicates that the history—of the messages previously received at the second device () differs from thehistory of messages previously sent from the first device ().
