register \- command to register set-top-box identity with signer
.B mux/register
.I signer
.I Register
is intended for use on a set top box (or similar device).
It connects to
.IR signer ,
a machine configured to sign certificates,
and obtains an authenticated certificate based on the contents of
.L /nvfs/ID
(the set top box ID in non-volatile memory).
The certificate is saved in the file
.L /nvfs/default
for later use.
If no
.I signer
is named explicitly, the
named in
.IR db (6)
is used instead.
There are several phases to obtaining the certificate.
.IP 1.
The register command interacts with
.IR signer (8)
on the signing host
to construct the certificate. This certificate is `blinded' by a random bit mask, sent back to
.I register
which displays it in textual or graphical form to
the user.
.IP 2.
The user running
.I register
must use an independent,
secure mechanism (for example, an untapped telephone call)
to communicate with a human agent at the
site acting as
.IR signer .
That agent runs
.I verify
.IR signer (8))
to display the same `blinded' certificate that was
shown to
.IR register 's
user at the client.
Once the agent is convinced that the `blinded' certificate has been delivered to the correct party, the agent tells
.I verify
to accept the identity of the caller.
.IP 3.
.I Register
then connects to the
.I countersigner
process (see
.IR signer (8))
to obtain the bitmask needed to `unblind' the previously received certificate.
This step can only validly be performed after the successful
completion of
.I verify
on the
.I signer.
