..... and I have my perspective ... that of mapping transactions to AADS-
model (account
authority digital signature ... distinct from certification authority
digital signatures);
if you have an account ... then the account-authority can support
registering your public-key
in the account record (electronic business process analogous to signature
card) ... and
support electronic operations against the account ... w/o requiring
certificates. it is what
i've been doing in x9.59; financial payment object that works across all
kinds of
financial accounts. it also eliminates various types of systemic risks that
would be
introduced by CAs into financial systems.

A few of us were talking in the FC98 dining room yesterday about the
underwriting of digital bearer certificates using my pet market model,
where the trustee is a plain old bank, and the underwriter(mint) is a
strictly net-based entity with an account at the trustee and a wire through
the trustee to the book-entry world of banks for exchangibility into
meatmoney. In that model, for the time being, the trustee is about as
regulated as you get, the underwriter is known by virtue of having an
account at the trustee, and you and I both are known to our banks when we
bring money onto and pull it off of the net. Render unto FINCEN, and all
that. However, on the net, the underwriter doesn't know us from Adam (Back
or Shostack :-)). The trustee only knows us as much as any bank doing a
"foriegn" ATM disbursement (and deposit, which is impossible now). So, once
you get to the net, *everything* is up for grabs, with total anonymity,
modulo the real or imagined regulatory influence of the patentholder ;-).
