46.4 Certificates Technical Reference
OCSP
OCSP (Online Certificate Status Protocol) allows an application or device to check
whether a certificate is valid. With OCSP the ZyWALL checks the status of
individual certificates instead of downloading a Certificate Revocation List (CRL).
OCSP has two main advantages over a CRL. The first is real-time status
information. The second is a reduction in network traffic since the ZyWALL only
gets information on the certificates that it needs to verify, not a huge list. When
the ZyWALL requests certificate status information, the OCSP server returns a
“expired”, “current” or “unknown” response.
