RE: A PKI Question: PKCS11-> PKCS12
try bank debit card infrastructure. there is a hardware token/box that is
protecting the bank's "key" which then all of the individual account keys
are encoded with. for a large bank, there could be dozens of these hardware
units to handle the debit transaction load. In addition, there are copies
of the keys likely escrowed in some other institution's safe deposit box
(aka keeping the escrow in the same institution's safe deposit boxes could
represent a collusion risk).
It is slightly analogous to a CA model (in that the bank's key is encoding
the account key as opposed to signing the account key) ... except then all
transactions are coming back to the account-authority (i.e. the
account-authority and the relying party are the same), and the hardware box
gets fed the encoded account information, the transaction ... and validates
the transaction.
