We consider the predictio...

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 authenti...

With the growth of electronic markets, designing double auction mechanisms that are applicable to emerging market structures has become an important research topic.
