Trust anchor — in cryptographic systems with hierarchical structure is an authoritative entity for which trust is assumed and not derived.
In X.509 architecture, a root certificate would be the trust anchor from which whole chain of trust is derived. The trust anchor must be in possession of the trusting party beforehand to make any further certificate path validation possible.
In most operating systems, the trust anchor is a collection of X.509 certificates of certification authorities that come preinstalled with the operating system, or is built into an application (such as web browser).
Famous quotes containing the words trust and/or anchor:
“And such the trust that still were mine,
Though stormy winds swept o’er the brine,
Or though the tempest’s fiery breath
Roused me from sleep to wreck and death.
In ocean cave, still safe with Thee
The germ of immortality!
And calm and peaceful shall I sleep,
Rocked in the cradle of the deep.”
—Emma Hart Willard (1787–1870)
“This could be the day.
I could slip anchor and wander
to the end of the jetty
uncoil into the waters
a vessel of light moonglade
ride the freshets to sundown”
—Audre Lorde (1934–1992)
