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:
“I cannot trust myself to put in words what I feel at this time. Every kind thought that is in your minds and every good wish that is in your hearts for me finds its responsive wish and thought in my mind and heart for each of you. I love this city. It has been my own cherished home. Twice before I have left it to discharge public duties and returned to it with gladness, as I hope to do again.”
—Benjamin Harrison (1833–1901)
“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)
