0. What to know

• Rijndael shows how advanced algebra has practical importance.

• You are not responsible for learning the details of the Rijndael algorithm.

• However, we'll be continuing to study the principles of finite fields that are involved, so there may be future homework on that aspect referring to this handout. If so, you will be responsible for learning that material.

• If you would like to learn more, you can take Math 116 (Mathematical Cryptology).
