CHAPTER 13
The Certificates Screens
13.1 Overview
Use the TOOLS > Certificates screens to manage public key certificates on the
WiMAX Modem.
The WiMAX Modem can use public key certificates (also sometimes 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.
Public key certificates are used by web browsers to ensure that a secure web site
is legitimate. When a certificate authority such as VeriSign, Comodo, or Network
Solutions (to name a few) receives a certificate request from a website operator,
they confirm that the web domain and contact information in the request match
those on public record with a domain name registrar. If they match, then the
certificate is issued to the website operator, who then places it on his site to be
issued to all visiting web browsers to let them know that the site is legitimate.
