Blueheart Alison Sinclair Harper Science Fiction ISBN 0-06-105820-3 $6.50 US I quote from the 'fly' (or whatever it's called), the facing page to the first page of chapter 1. "If you purchased this book without a cover, you should be aware that this book is stolen property." They've been doing this for at least 20 years. ____________________________________________________________________ Before a larger group can see the virtue of an idea, a smaller group must first understand it.

"Cryptography and Evidence," philosophy, and ZKPs
by dmolnar 05 Feb '01

05 Feb '01

I just came across this PhD thesis in philosophy: "Cryptography and Evidence" Michael Roe http://www.research.microsoft.com/users/mroe/THESIS.PDF I have just started to read it. The thesis aims to give a careful account of just what a protocol can and can *not* establish in the context of repudiation. I'm pretty excited to see it, because I know of little material on ZKPs from a "philosophical" point of view (besides Cypherpunks archives). What's more, the discussions I have seen with friends and such tend too often to focus on the probabilistic nature of ZKPs, most often questioning whether a probabilistic "proof" is a contradiction in terms. This isn't interesting to me - not least because you can make perfectly rigorous statements about the soundness of ZKPs. In the end, no matter what you call it, it must convince you. Better, but still short of the discussion I'd like, is that found in "The Ongoing Value of Proof" Gila Hanna http://fcis.oise.utoronto.ca/~ghanna/pme96prf.html which shows an understanding of what ZKPs are, but regretfully limits itself only to a brief comment that "..the most significant feature of the zero-knowledge method is that it is entirely at odds with the traditional view of proof as a demonstration open to inspection. This clearly thwarts the exchange of opinion among mathematicians by which a proof has traditionally come to be accepted." I wish the author had commented more, because as it stands I do *not* think that it is so clear that a ZKP is "entirely at odds" with the traditional view of proof. The interaction in a ZKP is certainly a "demonstration," and every round is open to inspection. Perhaps you could argue that the commitments used in ZKPs create a part of a ZKP "not open to inspection," but the commitment values and decommits certainly are open to inspection, so how far can you push this? If you're familiar with Wittgenstein's "say vs. show" distinction, this is how I might put it as a rough guide -- a ZKP's transcript is simulable, therefore "says nothing," but the interaction "shows" the truth of a proposition. (To some bounded probability of error.) Does anyone know of other works which comment on ZKPs from standpoints in philosophy? (or otherwise outside the usual standpoint of trying to develop new technical results about ZKPs?) Thanks, -David

Your request arrived on the cypherpunks maimling list, a general discussion forum for cryptology, so I don't quite see how your query is particularly relevant to that topic. That aside, assuming you're asking about /machine names and web addresses/, then you're asking about fundamental domain name system operating issues, and as such, you should be able to find the answer to your question in any of dozens of texts, or else a quick web search will reveal all you need to know. Focus your query on "DNS reverse lookup" or similar. Note: for some long time, Microsoft, in their (questionable) wisdom, released severely incomplete implementations of DNS tools, effectively making reverse lookup infeasible. I'm almost certain that they've now had to bow to peer pressure and implement it properly, so to some extent, your success will depend on how current your Microsoft installation actually is. Alternatively, if you're instead asking how to determine someone's street address given only an IP address, then you seek an answer as daft as the one you'd get if you asked "How do I determine someone's street address given only a malicious letter (which presumably has no return address) that they've sent to me". I suppose it might be doable in some sense (you might be able to find the postal address of the ISP used by your malicious correspondent), but to attempt such an investigation would mark you as a great prat. -- Kevin. ----------------------------------------------------------------- Visit our Internet site at http://www.reuters.com Any views expressed in this message are those of the individual sender, except where the sender specifically states them to be the views of Reuters Ltd.
