I have just remembered that there is a card game that is based on covert 
channels. Tt is "Contract Bridge". Covert channel is established and 
used in bidding process. There is also a way to introduce a noise in the 
channel to confuse opponents covert channel.


This game might be a good sample to explain what is a covert channel in 
the protocol in security books or articles.
