Following is a list of code names that have been used to identify computer hardware and software products while in development. In some cases, the code name became the completed product's name, but most of these code names are no longer used once the associated products are released.
The Microsoft Authenticode code signing system uses X.509 to identify authors of computer programs. The OPC UA industrial automation communication standard uses X.509. SSH generally uses a Trust On First Use security model and doesn't have need for certificates. However, the popular OpenSSH implementation does support a CA-signed identity model ...
A web browser will give no warning to the user if a web site suddenly presents a different certificate, even if that certificate has a lower number of key bits, even if it has a different provider, and even if the previous certificate had an expiry date far into the future.
In computer security, digital certificates are verified using a chain of trust. [1] The trust anchor for the digital certificate is the root certificate authority (CA).. The certificate hierarchy is a structure of certificates that allows individuals to verify the validity of a certificate's issuer.
CRL for a revoked cert of Verisign CA. There are two different states of revocation defined in RFC 5280: Revoked A certificate is irreversibly revoked if, for example, it is discovered that the certificate authority (CA) had improperly issued a certificate, or if a private-key is thought to have been compromised.
A non-technical, social difficulty with a Web of Trust like the one built into PGP/OpenPGP type systems is that every web of trust without a central controller (e.g., a CA) depends on other users for trust. Those with new certificates (i.e., produced in the process of generating a new key pair) will not likely be readily trusted by other users ...

The careful design and implementation of a system's trusted computing base is paramount to its overall security. Modern operating systems strive to reduce the size of the TCB [not verified in body] so that an exhaustive examination of its code base (by means of manual or computer-assisted software audit or program verification) becomes feasible.
