I understand public key encryption, public key authentication, how digital signatures work and challenge-response authentication, but what confuses me is when they are all combined, and the question can be asked "what processes does the supplicant and verifier go through if public key encryption was used in initial challenge-response authentication?"

  • Righto, so I understand public key encryption, public key authentication, how digital signatures work and challenge -response authentication, but what confuses me is when they are all combined, and the question can be asked "what processes does the supplicant and verifier go through if public key encryption was used in initial challenge-response authentication?". – Benjamin M Mar 31 '16 at 23:00

if you're elaborating the key on this very early stage - it's pre-seed only, that means that both sides have it before they even decided to start a session and thay are trusting it. That's why the licensed CD/DVD media is so hologram-protected e.t.c. : they're carrying a very valuable and vital set of pre-seeded keys already in a distro, making MitM's impossible.
