Since your system would only be as strong as the methiod of transporitng
the key (PGP, SSH, whatever), isn't OTP a little excessive?

I've done some google and freshmeat searches but didn't find anything
that seemed to fit the bill.  The closest thing I found was E-Pad which
seems to be more related to file encryption than authentication.

I'm interested in coding a one-time pad authentication system; similar
to SecurID or other types of token authentication only with software
tokens.  The administrator would generate the one-time pads for each
user and distribute them using whatever secure method gets coded (PGP,
SSH, or whatever).

The user then has a software token on their machine with the token code
that changes either every use, or uses some type of challenge/response
system, blah blah blah.  This token is used to log into systems,
etcetera.

I'd be interested in knowing if such an open-source tool exists, and if
not who would be interested in working on it with me (email me privately
if interested).
