Term Project: Codes

In Algebra, we are doing a term project in codes. We have to make three codes and explain how to solve them. Below are three of the codes my partner and I came up with. Each is accompanied with a little information regarding how to solve it. See if you can decipher them. Answers shall be given in my next post.

Vigenere Cipher

• This cipher requires a keyword
• This cipher requires a Cipher Box (below)

(Hint: The keyword is a country famous for its dynasties and inventions. This country has five letters in its name)

Code: I V W Q J Q I

Substitution Cipher

• This cipher replaces letters with other letters or symbols

(Hint: A=A, B=D, C=C)

Code: S O H A T SO G O O F

Fibonacci Sustitution

• A substitution cipher created by my partner and I
• Based on the Fibonacci Sequence

(Hint: The code is in a reverse order)

Code: 75025/233/377/10946/55/196418/21/13/987/196418/21/4181/233/377/34
