IEEE P1687 is a valuable tool for accessing on-chip instruments during test, diagnosis, debug, and board configuration. However, most of these instruments should not be available to an end user in the field. We propose a method for hiding instruments in a P1687 network that utilizes a “locking” segment insertion bit (LSIB) that can only be(More)
We present an empirical investigation into the prevalence and impact of distributed denial-of-service (DDoS) attacks on operators in the Bitcoin economy. To that end, we gather and analyze posts mentioning “DDoS” on the popular Bitcoin forum bitcointalk.org. Starting from around 3 000 different posts made between May 2011 and October 2013, we document 142(More)
Cell-aware faults have previously been proposed to more effectively detect defects within gates. At the same time, n-detect test sets that provide multiple detections of each stuck-at fault are often used to maximize the detection of unmodeled defects. However, n-detect test sets are often not particularly effective at fortuitously detecting all untargeted(More)
