Cryptography without/before PKC

Distinct from the research into public-key crypto, there's history and research about the practicalities of living *without* the mathematical/complexity assumptions that underlie most PKC: key negotiation including via multiple third parties, hash signatures, etc. Don't have the round tuits quite yet (and it doesn't really belong in this specific article), but throwing it out there if it piques anyone else's interest.
