The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded. Carol's OCSP responder confirms that Alice's certificate is still OK, and returns a signed, successful 'OCSP response' to Bob.
OCSP stapling is designed to reduce the cost of an OCSP validation, both for the client and the OCSP responder, especially for large sites serving many simultaneous users. However, OCSP stapling supports only one OCSP response at a time, which is insufficient for certificate chains with intermediate CA certs. [26] [27]
It also introduces latency to connections, as the responder must be queried before a new connection can be used. [18] A 2018 study found that 1.7% of requests to responders were unavailable at the network level, and a further c. 2% produced unusable OCSP responses, with significant hetereogeneity across CAs and client vantage points.
