X–Y–Z
A standard that regulates global, distributed directory services databases; it’s also known as a white pages directory (because lookup occurs by name, rather than by job role or other categorized information, as in a yellow pages type of system).
A digital certificate that uniquely identifies a potential communications party or participant. Among other things, an X.509 digital certificate includes a party’s name and public key, but it can also include organizational affiliation, service or access restrictions, and a host of other access- and security-related information.
