Summary: We evaluate seven techniques for extracting unique signatures from NAND flash devices based on observable effects of process variation. Four of the techniques yield usable signatures that represent different trade-offs between speed, robustness, randomness, and wear imposed on the flash device. We describe how to use the signatures to prevent counterfeiting and uniquely identify and/or authenticate electronic devices.
