An experimental, end-to-end, network packet encryption system developed in a working prototype form by BBN and the Collins Radio division of Rockwell Corporation in the 1975-1980 time frame for the U.S. DoD. BCR was the first network security system to support TCP/IP traffic, and it incorporated the first DES chips that were validated by the U.S. National Bureau of Standards (now called NIST). BCR also was the first to use a KDC and an ACC to manage connections.
