1. Clone Source

Check date with the 'date' command, and fix it with command like 'date -s <Tue Jul 4 13:39:36 EDT 2023>' if needed.

git clone git@github.com:Mellanox/spdm-test.git
(or git clone https://github.com/Mellanox/spdm-test.git)
cd spdm-test
git submodule update --init --recursive

2. Apply Patches

make patches

Note: Run the commands below if git error message "Please tell me who you are" is printed at this step.

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"
 

3. Build

# Only needed once to install cmake. Run 'apt-get update' as needed if the command below fails. apt install cmake
(or 'yum install cmake' on centos/redhat based distribution)

make

4. Run

make run

It'll start to run 'spdm-proxy' first, then 'spdm_requester_emu'.

Note: Need to sign and load kmod/mlxbf-mmio.ko first if Linux kernel-lockdown is enabled.

Expected output example:

 ...  
 write file - device_cert_chain_0.bin  
 ...  
 !!! verify_measurement_signature - PASS !!!  
 write file - device_measurement.bin  
 ...  
 

device_cert_chain_0.bin & device_measurement.bin are located under spdm-emu/build/bin/

CORIM/COMID Verification

Convert SPDM measurement evidence to json file

cd spdm-emu/build/bin

python3 ../../spdm_emu/spdm_device_verifier_tool/SpdmMeasurement.py meas_to_json --meas device_measurement.bin --alg sha512 -o device_measurement.json

# cat device_measurement.json | less
