point 5. Which of the following PUFs are memory based. Check all that apply. Ring Oscillator PUF Butterfly PUF SRAM PUF Paper PUF point 6. Which of the following methods can make the RO PUF more reliable? Check all that apply Use error correction coding to correct the PUF bit flips Use better methods or equipment to measure the delay gap more precisely. Use a small threshold for RO pair selection Run the RO pairs for a longer time 7. Which of the following features make the configurable RO PUF reliable? Check all that apply. It includes all the inverters so the maximal delay gap can be achieved Inverters that are sensitive to temperature or supply voltage can be excluded. The configuration vector is selected after the chip is fabricated. One RO can use more inverters than the other to increase the delay gap. point 8. Which of the followings need to be considered when a true random number generator (TRNG) is evaluated? Check all that apply. the source of entropy for the TRNG complexity of implementing the TRNG power efficiency of the TRNG point 9. When an FPGA system developer detects a hardware Trojan from the FPGA chip he has purchased, where the hardware Trojan may come from? Check all that apply. EDA tool vendor whose design tool is integrated in the FPGA design environment FPGA vendor who designed the FPGA chip IP vendor whose IP is included in the FPGA chip Foundry that fabricates the FPGA chip 10. When Bob purchases an FPGA-based system, which of the following security vulnerabilities and attacks he should consider. Check all that apply Whether the FPGA configuration bitstream file is encrypted or protected User's sensitive information leaking from the system Hardware Trojan inside the FPGA-based system Reverse engineering that attempts to reveal the design information of the system
