VITI: A Tiny Self-Calibrating Sensor for Power-Variation Measurement in FPGAs

On-chip sensors, built using reconfigurable logic resources in field programmable gate arrays (FPGAs), have been shown to sense variations in signalpropagation delay, supply voltage and power consumption. These sensors have been successfully used to deploy security attacks called Remote Power Analy...
