Module proj_billing::billing::three_party [−] [src]

Three Party Billing Scheme

  1. Utility provider
  2. Smart meter (trusted by all parties)
  3. Customer hardware (calculates the bill and performs the external communication to the provider)

The meter signs and commits to readings. The consumer may then perform computations on them which can be blindly verified by the utility provider, without the provider having to know the individual readings.

For the implementation of BillingProtocol (for tests), the Customer and Smart Meter are handled together.
