1. I am having a hard time understanding low exponent attacks. I understand how they are useful, but I am not understanding the theorem that explains how to use them. More specifically, how do you choose d? There are guidelines, but it seems like there would be a lot of choices.
2. I have never heard about a timing attack, and it seems like that greatly jeopardizes the security of RSA. The use of derivatives to find the times also is interesting and is another area of math that I get to be refreshed on. I would be really interested to know what preventative features, specifically, can be added to a physical implementation to prevent the timing attack.
