The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. 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.
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]
The size of the potentially-revocable set of certificates places requirements on the scalability of the revocation mechanism. [4] Chuat et al. (2020) call revocation "notoriously challenging". [8] In 2022, RFC 9325 characterised certificate revocation as an important problem with "no complete and efficient solution".
Browsers and other relying parties might use CRLs, or might use alternate certificate revocation technologies (such as OCSP) [4] [5] or CRLSets (a dataset derived from CRLs [6]) to check certificate revocation status. Note that OCSP is falling out of favor due to privacy and performance concerns [7] [8] [9]. Subscribers and other parties can ...
The group's primary focus [15] was promoting an understanding of the importance of certificate revocation checking and the benefits of OCSP stapling. The protocol is intended to ensure that web users are aware when they visit a web site with a revoked or expired SSL certificate. [16]
Checking Revocation Status: each certificate is checked against Certificate Revocation List (CRL) or online status protocols (such as OCSP) to ensure it has not been revoked. Applying Policies: any additional policies specified by the relying party are applied to ensure the certificate path complies with required security standards and practices.
X.509 and RFC 5280 also include standards for certificate revocation list (CRL) implementations. Another IETF-approved way of checking a certificate's validity is the Online Certificate Status Protocol (OCSP). Firefox 3.0 enabled OCSP checking by default, as did versions of Windows from at least Vista and later. [9]
Without revocation, an attacker would be able to exploit such a compromised or misissued certificate until expiry. [31] Hence, revocation is an important part of a public key infrastructure. [32] Revocation is performed by the issuing CA, which produces a cryptographically authenticated statement of revocation. [33]
