Click Cancel to quit and return to the previous screen. 15.4 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 Zyxel Device 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 Zyxel Device only gets information on the certificates that it needs to verify, not a huge list. When the Zyxel Device requests certificate status information, the OCSP server returns a "expired", "current" or "unknown" response. NWA50AX User's Guide 137
