Chapter 19 Certificates
Certification authorities maintain directory servers with databases of valid and revoked
certificates. A directory of certificates that have been revoked before the scheduled expiration
is called a CRL (Certificate Revocation List). The ZyXEL Device can check a peer's
certificate against a directory server's list of revoked certificates. The framework of servers,
software, procedures and policies that handles keys is called PKI (Public-Key Infrastructure).

19.1.1 Advantages of Certificates

Certificates offer the following benefits.
• The ZyXEL Device only has to store the certificates of the certification authorities that
you decide to trust, no matter how many devices you need to authenticate.
• Key distribution is simple and very secure since you can freely distribute public keys and
you never need to transmit private keys.

19.2 Self-signed Certificates

You can have the ZyXEL Device act as a certification authority and sign its own certificates.

19.3 Configuration Summary

This section summarizes how to manage certificates on the ZyXEL Device.
