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:
“Girls are apt to imagine noble and enchanting and totally imaginary figures in their own minds; they have fanciful extravagant ideas about men, and sentiment, and life; and then they innocently endow somebody or other with all the perfections for their daydreams, and put their trust in him.”
—Honoré De Balzac (1799–1850)
“The coward wants resolution, which the brave man can do without. He recognizes no faith above a creed, thinking this straw by which he is moored does him good service, because his sheet anchor does not drag.”
—Henry David Thoreau (1817–1862)
