FPGA accelerated Client-Side of Federated Learning with BGV Homomorphic Encryption Algorithm

Prerequisite

Vivado
Vitis
Vitis-HLS
Xilinx XRT

Build and Test

1. Test the functionaility and build xo module.

cd build/
vitis_hls run_hls.tcl

Modify set_top and set hls_exec appropriate to the purpose. hls_exec 1 or hls_exec 2 only test the functionality and hls_exec 3 will generate *.xo file.

2. Build xclbin file.

v++ -l -t hw --platform xilinx_u55c_gen3x16_xdma_3_202210_1 --kernel {top_module} {top_module}.xo -o {top_module}.xclbin

3. Sign xclbin file

sudo /opt/xilinx/xrt/bin/xclbinutil --private-key /var/lib/shim-signed/mok/MOK.priv --certificate /var/lib/shim-signed/mok/MOK.der --input {top_module}.xclbin --output {top_module}_signed.xclbin

4. Compile host.cpp At the top directory, run make host.

Note

to build and simulate LeNet5, change the project root directory in test/test_utils.h
