Resumen
Exchanging FPGA-based implementations of cryptographic algorithms during run-time using netlist randomized versions has been introduced recently as a unique countermeasure against side channel attacks. Using partial reconfiguration, it is possible to shuffle between structurally different but functionally similar versions of a cryptographic implementation. The resulting varying power profile enhances the resistance against power-based side channel attacks. While side channel leakage is reduced, costs in terms of additional resources and/or lowered throughput are often increased due to the overheads of the required online partial reconfiguration. In this work, we provide an in-depth evaluation of the leakage-area-throughput trade-off.
