FPGAcrypto is a collection of scripts for testing secure computation of cryptographic algorithms on FPGA accelerators by generating Verilog code which is converted to C++ and compiled to binary format using Verilator, and then benchmarked using gem5. This repository was created as part of a term project for CPRE 5810, Computer Hardware Architecture, at Iowa State University.
This subdirectory features a collection of Verilog scripts corresponding to various cryptographic design implementations, as well as an basic example script at example.v. These scripts are converted to C++ by Verilator.
This subdirectory features a collection of testbenches which can be used for contextualizing the Verilog scripts, including an example at example_tb.cpp. These scripts are interpreted by Verilator at compile time.
This subdirectory features a collection of various gem5 configuration scripts that can be used to simulate a workload on an appropriate FPGA mockup and obtain timing side-channel data
This configuration assumes that you have Verilator installed somewhere on PATH. This can be done with an appropriate package manager, such as sudo apt install verilator, though you can also clone the repository and compile from source yourself. Once you have done this, you can compile the Verilog script/C++ testbench using verilator --cc ./designs/<script>.v --exe ./testbenches/<testbench>.cpp. It can then be compiled with make -j -C ./obj\_dir/ -f V<script>.mk V<script>. The compiled binary can then be run with ./obj\_dir/V<script> or used as a workload in an appropriate gem5 configuration with /path/to/gem5/build/.../gem5.opt /path/to/gem5/configs/.../config.py ./obj_dir/V<script>. Note that gem5 functionality requires having previously built a gem5 config with scons /path/to/gem5/build/../gem5.opt -j nproc
