Our main contributions are (i) a generic architecture for using GC/OTP modularly, and (ii) hardware implementation and efficiency analysis of GC/OTP evaluation. We implemented two FPGA-based prototypes: a system-on-a-programmable-chip with access to hardware crypto accelerator (suitable for smartcards and future smartphones), and a stand-alone hardware implementation (suitable for ASIC design). We chose AES as a representative complex function for implementation and measurements. As a result of this work, we are able to understand, evaluate and improve the practicality of employing GC/OTP as a leakage-resistance approach. Last, but not least, we believe that our work contributes to bringing together the results of both theoretical and practical communities.
