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:
“Ideas are only lethal if you suppress and don’t discuss them. Ignorance is not bliss, it’s stupid. Banning books shows you don’t trust your kids to think and you don’t trust yourself to be able to talk to them.”
—Anna Quindlen (b. 1952)
“It is a far, far better thing to have a firm anchor in nonsense than to put out on the troubled seas of thought.”
—John Kenneth Galbraith (b. 1908)
