The FPGA Assurance for Navy and Government Systems (FANGS) and Reverse Engineering Embedded Firmware (REEF) Labs of NSWC Crane provide technical expertise and tool solutions for securing DoD programs and systems. FANGS and REEF are part of JFAC for collaborating with other DoD entities while also collaborating closely with industry and academia. The REEF Lab supports firmware assurance throughout the product lifecycle using forensic and vulnerability analysis for firmware as well as firmware feature verification by utilizing binary extraction, disassemblers/decompilers, and debuggers. The FANGS Lab assures the entire FPGA lifecycle with SME support, V&V of performer tools, and R&D solutions. Tools presented at GOMACTech and developed by the FANGS Lab for FPGA Assurance include the Security Mitigation Enforcer (SeME) and Bitstream Analysis Toolkit (BAT).
