ARPANET encryption devices

rdf:langString ARPANET encryption devices

rdf:langString The ARPANET pioneered the creation of novel encryption devices for packet networks in the 1970s and 1980s, and as such were ancestors to today's IPsec architecture, and High Assurance Internet Protocol Encryptor (HAIPE) devices more specifically. DuPont and Fidler provide a historical perspective of ARPANET encryption devices in the broader evolution of computer networks and cybersecurity. They focus primarily on the first such ARPANET device, the Private Line Interface (PLI). That said, the PLI was just the first in a series of devices created during the 1970s and 1980s in ARPANET-related research and development: * Private Line Interface (PLI) * Black-Crypto-Red (BCR) * Blacker * Internet Private Line Interface (IPLI)
