Read Section 2.3 of your text (Vigenere Cipher). I will talk about this briefly in class, but I’m going to let you learn it mostly from the book and Mission #1. So you should make sure you read 2.3 carefully again in advance of Mission #1.
Finish Chapter 1 of the Code Book.
Arrange with your group to meet sometime next week before the Groupwork due date of Friday, Sept. 2nd. I suggest you meet early in the week, because you may get stuck on some of the problems during the first meeting and have to meet again later in the week. Don’t leave it to the last minute.
