Preparation for Recitation on Why Cryptosystems Fail

Read Why Cryptosystems Fail. This paper is about a philosophy of cryptosystem design, with a focus on their use in financial institutions, and particularly in ATM (Automated Teller Machine) networks.

As you read, think about how this paper relates to other papers we've read in 6.033, despite the fact that we've covered nothing else on ATM networks.

Question for Recitation

Before you come to this recitation, write up (on paper) a brief answer to the following (really—we don't need more than a couple sentences for each question). If your TA has requested that you email your answer to them, you may do that instead, but it should still be handed in before your recitation begins.

Your answers to these questions should be in your own words, not direct quotations from the paper.

As always, there are multiple correct answers for each of these questions.
