(2) (Digital Signal Trust Company, Salt Lake City, UT, www.digsigtrust.com) An organization that sets up and manages PKI systems for companies and industry groups. Using third-party software, it serves as a certification authority (CA), manages the repository and provides a secure location for the private keys. Founded in 1996, Utah-based DST was the first licensed CA in the U.S. and the first PKI service organization. Utah was the first state in the U.S. to pass digital signature legislation.
In 2002, DST was acquired by Identrus LLC (www.identrus.com), a global leader in digital trust services and secure e-commerce. See PKI.
(3) (Data Storage Technology) A high-capacity magnetic tape technology from Ampex that is based on the digital composite D2 format for the broadcasting industry. It uses the same 19mm, helical scan transport, but provides higher capacities with Ampex's proprietary Data D-2 (DD2) format. DST cartridges range from 50 to 330GB and are suited for uncompressed digital video (movies, commercials, etc.) and high-resolution images as well as general data backup for huge databases. Ampex's Data Instrumentation Systems (DIS) tape technology is a counterpart line that provides optional modes and interfaces for data acquisition devices. See magnetic tape.
