Parameter Optimitzation for On-Chip Voltage Sensor


In a Multi-tenant FPGA scenario multiple users have their own partial reconfigurable region on a single FPGA. Each of theses regions allows a single user to implement her/his design, without being able to directly interact with the design of another user on the same FPGA. So-called Time to Digital Converters (TDCs) can be used to perform remote side-channel attacks in such multi-tenant FPGAs, to extract secrets from other users.

The TDC is used as remote power measurement unit of the FPGA. The working principle is to use a long path in which timing violations are caused. Since the delay of transistors are proportional to the supply voltage, the amount of timing violations is a measure of the devices power consumption.

Different publications have already shown that cryptographic implementations [1, 2] and neural networks [3] can be attacked with such sensors.

In this work, design parameters of the TDC should be explored, in order to evaluate the influence on measurements of the on-device power consumption.
