Sherlock Holmes also used this kind of cipher in his one story The Adventures of The Dancing Men. Unfortunately for her, it wasn’t that difficult to decode! Frequency analysis ( math – data! ) ) helps you figure out the most used letters in the alphabet. This form of code was used by Mary Queen of Scots when she was plotting against Elizabeth the First. So, instead of an A, you could write # or %, or any picture. Substitution cipher – instead of a letter, we use a symbol.Decoding depends a lot on frequency analysis with the alphabet. Caesar cipher is one of the simplest and most widely known encryption techniques.Semaphore is still an effective method of communication used between boats or for distress signals. It’s very similar to positions for the hands of a clock. You don’t necessarily need flags the important piece is the arm position. Semaphore: Semaphore is a cipher system that uses the position of two flags to represent letters.The example key shows one way the letters can be assigned to the grid. Pig Pen Code: The pigpen cipher is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.It was originally used to send a telegraph, but is still used today by amateur radio enthusiasts and for distress signals.

Refer to the class discussion on on exclusion/inclusion? When is it okay to exclude others (e.g., safety concerns) and when is not okay? Communication : Students must invent their own code or cipher OR they could also invent secret handshakes, door knocks, clothing (poppy pin, red scarf, yellow watch etc.), ways of answering a phone call, texting,…you get the idea.Symbolism: What metaphorical symbol would best represent your cause? E.g., dove for peace (have students draw one).Code name : How will you refer to yourselves?. A secret society must have something or someone to protect.
