  2. 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.

  3. 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]

    ITU standard that governs the format of certificates used for authentication in public-key cryptography. OCSP (RFC 2560). The Online Certificate Status Protocol (OCSP) governs real-time confirmation of certificate validity. PKIX Certificate and CRL Profile (RFC 3280). The first part of the four-part standard under development by the Public-Key ...

  6. Validation authority - Wikipedia

    en.wikipedia.org/wiki/Validation_authority

    It must be continuously updated with current CRL information from a certificate authority which issued the certificates contained within the CRL. While this is a potentially labor-intensive process, the use of a dedicated validation authority allows for dynamic validation of certificates issued by an offline root certificate authority. While ...

  7. Self-signed certificate - Wikipedia

    en.wikipedia.org/wiki/Self-signed_certificate

    RFC 5280 defines self-signed certificates as "self-issued certificates where the digital signature may be verified by the public key bound into the certificate" [7] whereas a self-issued certificate is a certificate "in which the issuer and subject are the same entity". While in the strict sense the RFC makes this definition only for CA ...

  8. SCVP - Wikipedia

    en.wikipedia.org/wiki/SCVP

    The SCVP server's response contains a set of certificates making up a valid path between the certificate in question and one of the trusted certificates. The response may also contain proof of revocation status, such as OCSP responses, for the certificates in the path. Once a certification path has been constructed, it needs to be validated.

  9. Certification path validation algorithm - Wikipedia

    en.wikipedia.org/wiki/Certification_path...

    In the standardized algorithm, the following steps are performed for each certificate in the path, starting from the trust anchor. If any check fails on any certificate, the algorithm terminates and path validation fails. (This is an explanatory summary of the scope of the algorithm, not a rigorous reproduction of the detailed steps.)
