comment Amateur question: two-way RSA?
The scheme that was described in the question is not TLS; TLS is quite different (e.g., considerably more complex; and probably more secure). The phrasing of this answer suggests that you could use what was suggested in the question and you would be fine; however, using what is suggested in the question probably isn't a good idea.

No "thank you". No "edit". Clean up the language.

comment What's efficient MPC protocol for determining if sum's bigger than y?
@Richard, yes, the input size is likely to matter (at least if you use a boolean circuit).

comment Which areas in CS will be (or have been) most affected by fully homomorphic cryptography?
@c3ntury, a great first step would be to do some reading on these topics. That will likely give you a much better sense of how to focus your essay. Start by searching for "homomorphic" on this site and on Wikipedia and on Google; you'll find some good information and some pointers to where to learn more, and that ought to give you a reasonable overview, for starters.

What research have you already done? We expect you to do some research on your own before asking here. (And, by the way, a bit of friendly advice: do your own homework. There's a reason your instructors assign you homework: because it will help you learn!)

comment Can substrings of a long string be efficiently authenticated?
@RickyDemer, once again, you are right and I was wrong. Sorry about that; I don't know what I was thinking.
