14.1-14.2, due on November 18

• I read through the material for lecture today, but really didn't understand any of it. Maybe I read through it too fast or maybe its just a little tough to get. But, I'm not really understanding the whole "door" analogy. Peggy wants to fool Victor as to which way she's going to go and wants him to think she knows how to get into the door? Not sure if that's what I was supposed to get out of that scenario. I also didn't really understand the Feige-Fiat-Shamir Identification Scheme. I'm really looking forward to lecture.
• I'm always wondering if anyone has access to my information after I used my check card for a purchase, and type in my PIN. Its a scary thing to think about. You always see those commercials on TV where the person's identity was stolen without them even knowing it. Now their credit score is horrible and their life is ruined. I appreciate there being methods out there to help protect us from this kind of fraud.
