it helped that the last homework had me practice working with signatures and creating two messages that are congruent with modular arithmetic. because of that, i was able to follow the reading fairly well. although i did get a little lost with the elgamal signature scheme explanation. the numbers and variables throw me off and it helps if i can work through an example myself. also i was wondering how it’s helpful that alice can choose a random k and keeps it to herself. i think it helps her compute the other variables, but that has always been a little confusing for me.
so i really like this electronic signature stuff. i like thinking about it, and i really enjoyed that last homework we did. i also love modular arithmetic (probably because it took me so long to get it and now i understand it and it’s awesome). i just think it’s so amazing to think about all the security that goes into cryptography. so much work, so much trust in those that do it for a living.
