The Box Openers- 15 Points

Authentication

Our team authenticated our messages by putting our initials in our code in the bottom left corner. We wrote our initials in our code so unless another team had our EDN it would be very hard for them to guess it.

Points

We earned the most points on the first day. We earned 9 points that day- 6 from the Eves and 3 from opening our own box.

Key System

On our best day, we used a secret key system for our code. For the last 2 days, we used a public key system (Diffie-Hellman).

Encryption/Decryption

Our team encrypted and decrypted our messages by counting how many times a line in a letter met with another line/how many “vertices” in the letter. For example, the letter A has 3 points when 2 lines meet. That was the first number. The second number was how many times the number had already appeared before. Since A is the first letter that has 3, we add a 1 behind it so A equals 31. Then we used addition, subtraction, division, and multiplication signs to figure out the numbers in our code. That is how we encrypted our code.
