Can someone give some background on zero knowledge protocols and how this pdf relates to the protocol?

  The wiki article should be a good start: http://en.wikipedia.org/wiki/Zero-knowledge_proof http://en.wikipedia.org/wiki/Zero-knowledge_proof

  I could tell you but, to trust my information, then how might you determine if I actually know what Zero Knowledge Protocols are without knowing them yourself?

  A good definition from the PDF: He wanted, in fact, to show that it is possible to convince without revealing, and so without unveiling his secret. Or from wikipedia [1]: In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information apart from the fact that the statement is indeed true.

    I think the privacy component is also important (somehow hidden in "without unveiling his secret", but not so clear imo). When Alice proves her knowledge to Bob, no external party would "believe in the proof", as A & B might have colluded.

  If interested in the subject, I'd suggest to have a look also at DAA - Direct Anonymous Attestation [1]. It's probably one of the most advanced protocols related to ZKP, part of the Trusted Computing Group specs, there are several newer versions on pairing-based crypto, there are implementations both software and hardware... in short, it's quite an interesting protocol.
