Cryptography (solving codes)

Year 10 students had a taste of MI5 when civil servant Jason Gray came to FHS to deliver a cryptography workshop. The students started by looking at Caesar cipher codes which were used in Roman times to hide messages from enemies by simply shifting the alphabet.

Next the students looked at methods to decrypt a message that has been hidden by relating the most commonly used letter in the alphabet to what appears in the code.  Finally moving on to solving modern day ciphers by using simultaneous equations.

“The workshop was informative and interesting, I would love to look at computer cryptography more now’” said one student.
