Section 4
Certificate
The P16-IP uses the Secure Socket Layer (SSL) protocol for any encrypted network traffic
between itself and a connected client. During the connection establishment the P16-IP has to
expose its identity to a client using a cryptographic certificate.
This certificate and the underlying secret key is the same for all P16-IP units and certainly will
not match the network configuration that will be applied to the P16-IP by its user. The
certificate' s underlying secret key is also used for securing the SSL handshake. Hence, this is a
security risk (but far better than no encryption at all).
However, it is possible to generate and install a new certificate that is unique for a particular
P16-IP. In order to do this, the P16-IP is able to generate a new cryptographic key and the
associated Certificate Signing Request (CSR) that needs to be certified by a certification
authority (CA). A certification authority verifies that you are the person you claim you are, and
signs and issues a SSL certificate to you.
The following steps are necessary to create and install an SSL certificate for the P16-IP:
1. Create an SSL Certificate Signing Request using the panel shown in the screen shot
above. You need to fill out a number of fields that are explained on the next page. Once
this is done, click on the Create button to initiate the Certificate Signing Request
generation. The CSR can be downloaded to your administration machine with the
Download CSR button (see the illustration on the next page).
2. Send the saved CSR to a CA for certification. You will get the new certificate from the CA
after a more or less complicated traditional authentication process (depending on the
CA).
3. Upload the certificate to the P16-IP switch using the Upload button.
