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.

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 15.7 on page 218

) 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.

Key

Type the key that the certification authority gave you.

Back

Click Back to return to the previous screen.

Click Apply to begin certificate or certification request generation.
