41.4 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.
