Objective
- Students will be able to encrypt and decrypt messages using the Caesar Cipher so they can develop a basic understanding of cryptography principles.
Links:
- Basics of Cryptography: Caesar Cipher: https://www.instructables.com/id/Basics-of-Cryptography-Caesar-Cipher/
Topics Discussed:
- Cryptography
- Caesar Cipher
- Shift Cipher
- Keywords
Assignment:
- Follow along with the in-class demonstration to learn how the Caesar Cipher (also known as the Shift Cipher) works, and how you can use it to encode and decode text messages.
- Follow the Instructable to learn how keywords can be incorporated with this cipher to make it more difficult to decrypt.
- I have placed 8 encrypted messages around the perimeter of the room. Work together to decrypt them all! Submit a Google Doc to my Google Classroom page with the decrypted messages by the end of the day tomorrow.
- Some of the decrypted messages lead to treasure! The first to decode each message gets the goods!
- Remember, you may work together, but each student must submit their own original document to the Google Classroom page by tomorrow to receive credit for the lab. Don’t put more than one name on your document, and don’t submit someone else’s document as your own!
