In such situations even a revocation list cannot help.

Updates to the revocation list arrive with new media and are automatically integrated.

Additionally, Microsoft maintains a global revocation list for devices that have been compromised.

Such keys are placed on a certificate revocation list or CRL.

The system can then compare these values to a revocation list, and if either the transmitter or receiver appears on that list, authentication fails.

This is, more or less, equivalent to the certificate revocation lists of centralized PKI schemes.

Opera always checks the certificate revocation list of the certificate's issuer and so they initially stated they did not need a security update.

Presumably the revocation lists are protected by a digital signature generated by NSA.

X.509 specifies, amongst other things, standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.

Certificate Revocation List (CRL)

X.509 also includes standards for certificate revocation list (CRL) implementations, an often neglected aspect of PKI systems.

It supports certificate revocation lists and the Online Certificate Status Protocol (OCSP).

Each revocation list is signed with a digital signature using the Digital Signature Algorithm; this is designed to prevent malicious users from revoking legitimate devices.

Each unit first makes sure that the other is not using a revoked key and if one has a more up-to-date key revocation list it transmits it to the other.

It was created as an alternative to certificate revocation lists (CRL), specifically addressing certain problems associated with using CRLs in a public key infrastructure (PKI).

If a particular set of keys is compromised, their corresponding KSV is added to a revocation list burned onto new discs in the DVD and Blu-ray formats.

The root CA certificates, the ones built-in to operating systems and Web browsers, include within them the URL of a Certificate Revocation List (CRL).

Since an OCSP response contains less information than a typical CRL (certificate revocation list), OCSP can use networks and client resources more efficiently.

The Kohnfelder thesis introduced the terms Certificate and Certificate Revocation List as well as introducing numerous other concepts now established as important parts of Public Key Infrastructure.

An authority revocation list (ARL) is a form of CRL containing certificates issued to certificate authorities, contrary to CRLs which contain revoked end-entity certificates.

Specifically, Entrust supplied certificate revocation list distribution points (CRL-DP), Patent 5,699,431, to Sun under a royalty-free license for incorporation of that capability into the Mozilla open-source libraries.

Because Verisign code-signing certificates do not specify a Certificate Revocation List Distribution Point however, there was no way for them to be automatically detected as having been revoked, placing Microsoft's customers at risk.

RFC 3280 "Internet X.509 Public Key Infrastructure (PKIX) Certificate and Certificate Revocation List (CRL) Profile"

Its purpose is to offer an easy to use interface for creating certification authorities and all related elements including X.509 digital certificates, certificate signing requests (CSRs) and certificate revocation lists (CRLs).

Rye, like other municipalities under the grant, has access to state lists of equipment for purchase, state archives and records, and revocation lists of licenses and permits from the State Department of Environmental Conservation.
