  2. Certificate revocation list - Wikipedia

    en.wikipedia.org/wiki/Certificate_revocation_list

    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 ...

  3. Online Certificate Status Protocol - Wikipedia

    en.wikipedia.org/wiki/Online_Certificate_Status...

    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.

  4. OCSP stapling - Wikipedia

    en.wikipedia.org/wiki/OCSP_stapling

    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]

  5. Certificate Authority Security Council - Wikipedia

    en.wikipedia.org/wiki/Certificate_Authority...

    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]

  7. Certificate revocation - Wikipedia

    en.wikipedia.org/wiki/Certificate_revocation

    OCSP suffers from scalability issues. It relies on the client having network access at the time of checking the certificate's revocation status; further, the OCSP responder must be accessible and produce usable responses, or else the check will fail and the client must choose between failing-soft and failing-hard.

  8. Delegated Path Validation - Wikipedia

    en.wikipedia.org/wiki/Delegated_Path_Validation

    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is checked against Certificate Revocation List (CRL) or online status protocols (such as OCSP) to ensure it has not been revoked.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.

  9. Certificate authority - Wikipedia

    en.wikipedia.org/wiki/Certificate_authority

    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]
