32.4 Technical Reference
The following section contains additional technical information about the features
described in this chapter.
OCSP
OCSP (Online Certificate Status Protocol) allows an application or device to check
whether a certificate is valid. With OCSP the NXC 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 NXC only gets information on the
certificates that it needs to verify, not a huge list. When the NXC requests
certificate status information, the OCSP server returns a “expired”, “current” or
“unknown” response.
