FPGAs are increasingly used in military applications, the security of a design when the part is powered off is an important property that needs to be analyzed. In this paper, we study data remanence in modern FPGAs using a custom 90nm FPGA designed for this test. The effects of temperatures, architecture, memory topology, and power off methods are analyzed. We find that different memory cells in the...
Using FPGAs, a designer can separate the design process from the manufacturing flow. Therefore, the owner of a sensitive design need not expose the design to possible theft and tampering during its manufacture, dramatically simplifying the process of assuring trust in that design. Modern FPGAs include bitstream security features that turn the fielded design trust problem into an information security...
