Country Type up to 127 characters to identify the nation where the certificate owner is

located. You may use any character, including spaces, but the ZyXEL Device

drops trailing spaces.

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.

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 and

then send it to the certification authority.

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.

Key Type the key that the certification authority gave you.
