FlexDriver IoT authentication offload example AFU

This repository contains an example AFU for FlexDriver, demonstrated in the paper FlexDriver: A Network Driver for Your Accelerator. The example accelerator receives CoAP packets, extracts a JSON web token (JWT), and validates the token using SHA-256.

Build instructions

To build, you will need to acquire FlexDriver IP (src/flc.dcp) from NVIDIA Networking, and use Xilinx Vivado 2019.2 to build.

vivado -source run_project.tcl
