Certificates
13.1 Overview
The VDSL Router can use certificates (also called digital IDs) to authenticate users. Certificates are
based on public-private key pairs. A certificate contains the certificate owner’s identity and public
key. Certificates provide a way to exchange public keys for use in authentication.
13.1.1 What You Can Do in this Chapter
• Use the Local Certificates screens to generate certification requests and import the VDSL
Router's CA-signed certificates ( Section 13.4 on page 173 ).
• Use the Trusted CA screen to save the certificates of trusted CAs to the VDSL Router ( Section
13.4 on page 173 ).
13.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Certification Authority
A Certification Authority (CA) issues certificates and guarantees the identity of each certificate
owner. There are commercial certification authorities like CyberTrust or VeriSign and government
certification authorities. The certification authority uses its private key to sign certificates. Anyone
can then use the certification authority's public key to verify the certificates. You can use the VDSL
Router to generate certification requests that contain identifying information and public keys and
then send the certification requests to a certification authority.
13.3 The Local Certificates Screen
Click Advanced Setup > Certificate to open the Local Certificates screen. This screen displays
the VDSL Router’s list of certificates and certification requests.
