Teaching about Protocols
When I teach protocols I often ask students about the protocol in our building for tardy students (they have to go to the attendance office, get a slip of paper with the time and signature from the admin who checked them in, and then they take that paper to their class and give it to their teacher, who can look at the current time and check if the slip is from today / this class period). I particularly like that this protocol example has a timestamp and authentication.
