Blacker (security)
From Wikipedia, the free encyclopedia
Blacker (styled BLACKER) is a U.S. Department of Defense computer network security project designed to achieve A1 class ratings (very high assurance) of the Trusted Computer System Evaluation Criteria (TCSEC).[1][2]
The first Blacker program began in the late 1970s, with a follow-on eventually producing fielded devices in the late 1980s.[3] It was the first secure system with trusted end-to-end encryption on the United States' Defense Data Network.[4]
The project was implemented by SDC (software), and Burroughs (hardware), and after their merger, by the resultant company Unisys.[5]
