Abstract
Techniques are disclosed for accelerating online certificate status protocol (OCSP) response distribution to relying parties using a content delivery network (CDN). A certificate authority generates updated OCSP responses for OCSP responses cached in the CDN that are about to expire. In addition, the certificate authority pre-generates cache keys in place of CDNs generating the keys. The certificate authority sends the OCSP responses and the cache keys in one transaction, and the CDN, in turn, consumes the new OCSP responses using the cache keys.
