In cryptography, a certificate revocation list (CRL) is "a list of digital certificates that have been revoked by the issuing certificate authority (CA) before their scheduled expiration date and should no longer be trusted". [1]
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.
Let's Revoke uses bit vectors of revocation statuses (called certificate revocation vectors, or CRVs) to allow large amounts of revocation statuses to be efficiently retrieved by clients. [4] CAs generate CRVs for their own certificates, with one CRV per expiration date. CRV maintenance for CAs is linear in the number of certificates issued ...

The only increased risk of OCSP stapling is that the notification of revocation for a certificate may be delayed until the last-signed OCSP response expires. As a result, clients continue to have verifiable assurance from the certificate authority that the certificate is presently valid (or was quite recently), but no longer need to ...
X.509 also defines certificate revocation lists, which are a means to distribute information about certificates that have been deemed invalid by a signing authority, as well as a certification path validation algorithm, which allows for certificates to be signed by intermediate CA certificates, which are, in turn, signed by other certificates ...
The Certificate Management Protocol (CMP) is an Internet protocol standardized by the IETF used for obtaining X.509 digital certificates in a public key infrastructure (PKI). CMP is a very feature-rich and flexible protocol, supporting many types of cryptography.
A Certification Practice Statement (CPS) is a document from a certificate authority or a member of a web of trust which describes their practice for issuing and managing public key certificates. [1] Some elements of a CPS include documenting practices of: issuance; publication; archiving; revocation; renewal
