raspberry-pi-client

Raspberry Pi Client

Demo for GDPR proof IOTA MAM for the Raspberry Pi. This client reads P1 data and sends it via IOTA MAM to authorized service providers.

Requirements

Features

This client in demonstrates:

• How a device can be paired with your 'digital house' called my home via IOTA
• How the Pi can send P1 data via IOTA MAM
• How service providers can be authorized to access data
• How access can be revoked

For more information on the role of the raspberry-pi-client see architecture and the scenarios.

Installation

yarn

Tests

yarn run test

Note that some tests take a long time because they attach messages to the Tangle.

Production

Requirements:

• Raspberry Pi with:
  • OS (code is tested with Raspbian Stretch Lite)
  • Internet connection
• P1 cable (RJ11 to USB) in smart meter and USB port of Raspberry Pi

Clone the raspberry-pi-client on your Pi:

ssh pi@<pi's IP>
git init
git remote add origin git@github.com:Alliander/decentralized-auth.git
git fetch
git checkout origin/master -- raspberry-pi-client

Install dependencies on Pi:

Install Node dependencies:

cd raspberry-pi-client
yarn i

Install NTRU quantum proof asymmetric encryption lib:

sudo apt-get install autoconf libtool # needed for ntrujs
git clone https://github.com/NTRUOpenSourceProject/NTRUEncrypt
cd NTRUEncrypt
./autogen.sh
./configure
sudo make install
cp /usr/local/lib/libntruencrypt* ~/raspberry-pi-client/node_modules/ntrujs/lib/
cp /usr/local/lib/libntruencrypt* ~/raspberry-pi-client/node_modules/ntrujs/lib/lib/
cd ~/raspberry-pi-client/node_modules/ntrujs/build
make
cp Release/addon.node ../lib/addon-linux-arm.node
cd ~/raspberry-pi-client

Set environment variables:

export IOTA_PROVIDER=xxxx
export IOTA_MIN_WEIGHT_MAGNITUDE=10
export SMART_METER_VERSION=2.2

Test installation with:

yarn run test

Running for real:

Generate a seed with cat /dev/urandom | LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1 and add it into the SEED environment variable:

export SEED=<seed>

Start the client with npm start.

Or run with new SEED without exporting it:

SEED=$(cat /dev/urandom | LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1) npm start

Running the application locally

• Checkout the code
• yarn
• yarn start

Run with specific seed:

• SEED=HWMLSSBKJOTBKVQTJE9OWPPMPZJTDUDIHMMUFIBQJCDJDPRNLAAG99J9UXZIKSQJDTUWFPSXJIZEJMTXV npm start

Run with random seed:

• SEED=$(cat /dev/urandom | LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1) npm start
