7.2, due on October 26

The Interesting

I thought the Baby Step, Giant Step section was really interesting and I was excited that I actually understood what they were talking about. It almost reminds me of a meet-in-the-middle attack where we start forwards and backwords then look for matches. 

The Challenging

This chapter was harder than most of the others for me to understand. I had a really hard time understanding what was going on with everything, especially with the introductory proof, the workings of the Pohlig-Hellman algorithm, and with the Index Calculus. In the index calculus, why are they substituting things into various congruences?
