Unit 3 Task

Task: What other interesting examples of codes from history or the modern-day (digital or non-digital) can you find to inspire or support a lesson about encoding and decoding messages?

Lester Hill created the Hill Cypher in 1929 which, at the time, was the  first to be able to operate on more than three letters or symbols during a
single encryption or decryption operation. A key matrix is created to encrypt messages and then the inverse of that matrix is used to decrypt messages. If the key matrix of inverted form of the key matrix is discovered, it is simple to decode the message.
