Bob, concerned that Alice's private key may have been compromised, creates an 'OCSP request' that contains Alice's certificate serial number and sends it to Carol. Carol's OCSP responder reads the certificate serial number from Bob's request. The OCSP responder uses the certificate serial number to look up the revocation status of Alice's ...
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 Online Certificate Status Protocol (OCSP) stapling, formally known as the TLS Certificate Status Request extension, is a standard for checking the revocation status of X.509 digital certificates. [1]
The Online Certificate Status Protocol (OCSP) allows clients to interactively ask a server (an OCSP responder) about a certificate's status, receiving a response that is cryptographically authenticated by the issuing CA. [29] It was designed to address issues with CRLs. [30] A typical OCSP response is less than 1 kB. [31]
In public key infrastructure, a validation authority (VA) is an entity that provides a service used to verify the validity or revocation status of a digital certificate per the mechanisms described in the X.509 standard and RFC 5280 (page 69).
Without revocation, an attacker would be able to exploit such a compromised or mis-issued certificate until expiry. [15] Hence, revocation is an important part of a public key infrastructure. [16] Revocation is performed by the issuing certificate authority, which produces a cryptographically authenticated statement of revocation. [17]
