Anders,
Current certification systems do "work", much as an ordinary telephone
directory works. The analogy would be closer if the publisher of the
phone book digitally signed each entry.
The phone book works because most people are honest and want to help
make things work. But I have no real way of knowing that the entry
for "Acme Hardware, Third Street" is indeed a hardware store, or can
be trusted to perform as I might expect it to.
People expect a digital-sig PKI to somehow automatically provide the
root of trust that is needed. Indeed, the terminology "root key",
"root CA" suggests as much. But unless a third party can be relied
upon to reimburse me for my losses, when I send a digital check to
"Acme Hardware" and recieve nothing in return, this third party is
really not much more than a telephone directory.
We want more, and need more from PK technology. The emerging PKIs
are a start, a component, and a limited one. Again, it does "work"
in a statistical sense, because most people are not crooks.
My 2 cents.
