Hashing hardware : identifying hardware during boot-time system verification
Modern systems measure the software loaded at boot-time to ensure the machine starts in a trusted state. Such measurements, however, do not include any information about the underlying hardware of the machine. Recent DRAM-based attacks and the growing complexity of the supply chain attest to the …

Scheduling real-time traffic in wireless networks
… dissertation concerns the problem of scheduling real-time traffic in wireless TDMA channels. The most important characteristic of real-time traffic is that it has straight end-to-end delay constraint. We begin the investigation by studying a scheduling principle which naturally achieves the best …
