Study questions, due Oct 4

• Which topics and ideas do you think are the most important out of those we have studied?
• The different types of attacks (in §1.1.1) like "Known plaintext", "chosen plaintext", etc&. This seems useful and these terms are relevant when discussing many encryption methods.
• §4.5 "Modes of Operation" also seems important, because it applies to many methods.
• Chapter 5, AES seems important, simply because it is a modern protocol.
• What kinds of questions do you expect to see on the exam?
• Hmmm, similar ones to homework problems. Perhaps at most a caesar or substution cipher. But that seems unlikely, just because of the time it would take. I'm gonna guess some math problems, like solving systems of congruences and inverting a matrix in Z_n and manipulating polynomials in Z_2[x] / (p(x)).
• What do you need to work on understanding better before the exam?
• Specifics of DES and AES, in case there are questions on it. Um also just checking to see if there are unknown unknowns (it's quite possible I don't know that I don't know something).
