You're right - now that I look at it in more depth, I'm not at all sure that it's a PHD in philosophy. As opposed to just an ordinary doctorate in some other field. Thanks for pointing this out... This makes me even more interested to find material which discusses zero-knowledge proofs from, say, a philosophy of math standpoint. or anything "interesting" yet outside the usual technical standpoint. As for your question, I don't know of any e-mail software which offers plausible deniability. Maybe something to add to gpg? -David On Wed, 31 Jan 2001, Wei Dai wrote:

I just came across this PhD thesis in philosophy:
"Cryptography and Evidence" Michael Roe http://www.research.microsoft.com/users/mroe/THESIS.PDF
Are you sure this is a thesis in philosophy? It seems to talk about the rather practical concerns of non-repudiation and its converse, plausible deniability. The paper reminds me of something I was wondering about: are there any email security programs that offer plausible deniability as an option? Sometimes you want to MAC a message with an authenticated symmetric key instead of signing it in order to preserve plausible deniability, but PGP for example doesn't seem to offer this.
