Trust Anchor Format
Abstract
This document describes a structure for representing trust anchor
information. A trust anchor is an authoritative entity represented
by a public key and associated data. The public key is used to
verify digital signatures, and the associated data is used to
constrain the types of information or actions for which the trust
anchor is authoritative. The structures defined in this document are
intended to satisfy the format-related requirements defined in Trust
Anchor Management Requirements.
