  • Multi-level security domain separation using soft-core processor embedded in an FPGA
    Patent number: 9971910
    Abstract: A system and method for operating multiple security domains on one circuit card assembly, using a field-programmable gate array (FPGA) with an embedded security domain separation gate providing the MAC between multiple soft-core CPUs also embedded in the FPGA. In one embodiment, the FPGA is segregated into two or more security domains with no data paths between soft-core CPUs in each security domain except through the security domain separation gate. The security domain separation gate applies rules to any information to be transmitted between the security domains to avoid transmission of malicious content and to avoid transmission of information of a certain classification level or type to a security domain at a lower classification level or type.
