6.5-6.7 and 7.1, due on October 28

• The backward RSA system is a little confusing for me. I understand the Ek and Dk from studying AES, and I understand that they cancel each other out. I'm not quite clear though, why, if Ek is known, that it will be difficult to find Dk. That's pretty much the only thing getting me still. The rest of it is pretty familiar, having already studied RSA.
• Discrete logs make sense to me. Not perfectly, but I understand most of it. I'm sure when we go over it in lecture I'll understand it better. But for now, I'm understanding how to go through the process and it seems like an easier way to find primitive roots, which is nice and helpful. :)
