Unit 3 task – Option 2


One Cipher from history is the Scytale from 120AD. This cipher requires both the sender and receiver to be in possession of a cylinder of wood, exactly the same diameter this is considered the “Key” and called the scytale. The sender then takes a long narrow piece of fabric and coils it around the scytale and writes the message in standard right-left format. The fabric is then removed from the scytale and can be scrunched up and hidden, until it is delivered to the receiver, who will then wrap it around their own scytale to reveal the message. Although this type of cipher is very simplistic I found it interesting as this to me seems like early coding. Children would also be able to make their own Scytale.
