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:
“Nevertheless, no school can work well for children if parents and teachers do not act in partnership on behalf of the children’s best interests. Parents have every right to understand what is happening to their children at school, and teachers have the responsibility to share that information without prejudicial judgment.... Such communication, which can only be in a child’s interest, is not possible without mutual trust between parent and teacher.”
—Dorothy H. Cohen (20th century)
“the anchor weeps
Its red rust downward,”
—Louise Bogan (1897–1970)
