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:
“To place absolute trust on another human being is in itself a disaster, both ways, since each human being is a ship that must sail its own course, even if it go in company with another ship.”
—D.H. (David Herbert)
“At anchor she rides the sunny sod,
As full to the gunnel of flowers growing
As ever she turned her home with cod
From Georges Bank when winds were blowing.”
—Robert Frost (1874–1963)
