A prototype implementation of the Privacy Preserving Measurement protocol.
ppm-prototype implements an obsolete version of the PPM specification. It will
not receive further updates, nor will bug reports be investigated.
The various binary targets get all their configuration (PPM parameters and HPKE
configs) from JSON files found in the standard location for config files. On
Linux, that's ~/.config/ppm-prototype elsewhere on other platforms.
To get started on Linux, you can use the config files from sample-config:
cp sample-config/parameters.json ~/.config/ppm-prototype/
cp sample-config/hpke.json ~/.config/ppm-prototype/
Run the leader thusly:
cargo run --bin leader
The leader will listen for connections on 0.0.0.0 at the port specified in
parameters.json. It will advertise the HPKE config in hpke.json.
Run the helper thusly:
cargo run --bin helper
The helper will listen for connections on 0.0.0.0 at the port specified in
parameters.json. It will advertise the HPKE config in hpke.json.
Once the leader and helper are running, run the client thusly:
cargo run --bin client
The client will generate random reports, encrypt them to the HPKE config
advertised by the leader specified in parameters.json and upload them. The
leader and helper will execute the aggregate protocol together.
After the client uploads inputs, run the collector thusly:
cargo run --bin collector
The helper and leader will execute the collect protocol together and transmit output shares to the collector, reassembling them into an aggregate.
