CMG-DCM Data Communications Module
Before your DCM can start sending authenticated data, it must
•
generate a cryptographic key pair;
•
request a certificate from a trusted Certificate Authority, and be
assigned one;
•
run a data server or transmitter using a protocol designed with
provision for authenticated seismic data (
e.g. CD1.0 and 1.1);
•
using the certificate and key, begin authenticating the data using
the method specified in the protocol.
These steps can be executed remotely, but must be carried out
separately for each installation.
Hardware authentication
Where a Spyrus crypto-token is installed, the program spyrus should
be used to set it up.
1. From a computer on the local network, use a suitable program to
open a ssh session with the AM. For example, from a Linux
computer:
ssh 10.82.0.129
where 10.82.0.129 should be replaced with the IP address of
the AM on your network.
2. Log in using the username and password you use to access the
AM's Web interface. (If you do not use a username and
password to access the AM's Web interface, you should obtain
one from your network administrator.)
3. Initialise the Spyrus card with the command
spyrus zeroize
followed by
spyrus start
You should see information messages coming from the Spyrus
card, as follows:
Initial state 8(Zeroized)
info::state: Zeroized
