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:
“The difference between tragedy and comedy is the difference between experience and intuition. In the experience we strive against every condition of our animal life: against death, against the frustration of ambition, against the instability of human love. In the intuition we trust the arduous eccentricities we’re born to, and see the oddness of a creature who has never got acclimatized to being created.”
—Christopher Fry (b. 1907)
“the anchor weeps
Its red rust downward,”
—Louise Bogan (1897–1970)
