revised Do per connection random keys solve the stream cipher key repetition issue?
removed "not my idea" disclaimer now that it is obviously a bad idea; move summary to top

comment Do per connection random keys solve the stream cipher key repetition issue?
1) Thanks, it took me a while to figure out what you were talking about but I see that protection of the shared secret in #1 is like OTP. 2) I was assuming for #2 that the secret key to be used for the rest of the session is encrypted using your stream cipher (with the random nonce sent). For specifics if that makes it easier, let's say the stream cipher could be AES-256-CTR, ChaCha20, or a Keccak based stream cipher. I will edit for clairty. 3) For the purpose of these questions I was assuming that there is one shared key ever, which seems like it should work. I'll add a 3rd case too.
