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 A directory of certificates that have been revoked before the scheduled expiration 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.
Figure 151   Certificate Configuration Overview
