Key Length Select a number from the drop-down list box to determine how many bits the
key should use (512 to 2048). The longer the key, the more secure it is. A
longer key also uses more PKI storage space.
Enrollment Options These radio buttons deal with how and when the certificate is to be generated.
Create a self-signed
certificate
Select Create a self-signed certificate to have the ZyXEL Device generate
the certificate and act as the Certification Authority (CA) itself. This way you do
not need to apply to a certification authority for certificates.
Create a certification
request and save it
locally for later
manual enrollment
Select Create a certification request and save it locally for later manual
enrollment to have the ZyXEL Device generate and store a request for a
certificate. Use the My Certificate Details screen to view the certification
request and copy it to send to the certification authority.
Copy the certification request from the My Certificate Details screen (see
Section 17.7 on page 254) and then send it to the certification authority.
Create a certification
request and enroll for
a certificate
immediately online
Select Create a certification request and enroll for a certificate
immediately online to have the ZyXEL Device generate a request for a
certificate and apply to a certification authority for a certificate.
You must have the certification authority’s certificate already imported in the
Trusted CAs screen.
When you select this option, you must select the certification authority’s
enrollment protocol and the certification authority’s certificate from the drop-
down list boxes and enter the certification authority’s server address. You also
need to fill in the Reference Number and Key if the certification authority
requires them.
Enrollment Protocol Select the certification authority’s enrollment protocol from the drop-down list
box.
Simple Certificate Enrollment Protocol (SCEP) is a TCP-based enrollment
protocol that was developed by VeriSign and Cisco.
Certificate Management Protocol (CMP) is a TCP-based enrollment
protocol that was developed by the Public Key Infrastructure X.509 working
group of the Internet Engineering Task Force (IETF) and is specified in RFC
2510.
CA Server Address Enter the IP address (or URL) of the certification authority server.
CA Certificate Select the certification authority’s certificate from the CA Certificate drop-
down list box.
You must have the certification authority’s certificate already imported in the
Trusted CAs screen. Click Trusted CAs to go to the Trusted CAs screen
where you can view (and manage) the ZyXEL Device's list of certificates of
trusted certification authorities.
Request
Authentication
When you select Create a certification request and enroll for a certificate
immediately online, the certification authority may want you to include a
reference number and key to identify you when you send a certification
request. Fill in both the Reference Number and the Key fields if your
certification authority uses CMP enrollment protocol. Just fill in the Key field if
your certification authority uses the SCEP enrollment protocol.
