SECMP0063 Ensuring correct Network Operator Certificates are placed on Electricity Smart Meters
This modification was discussed at the Working Group meeting on 5 June 2019 where the Working Group and the Proposer agreed that the modification was ready to progress. SECAS are now working with the DCC to finalise the business requirements before requesting a DCC Preliminary Assessment.
What is the issue?
Smart Metering Key Infrastructure (SMKI) Certificates are put on Smart Meters to ensure they communicate information securely and to the correct Organisations. The Proposer has estimated that the incorrect Network Certificate is placed on Electricity Smart Metering Equipment (ESME) in approximately 10% of cases, preventing the true Network Operator from communicating with the ESME.
What is the solution?
The proposed solution is only applicable for ESMEs. The MPAN core or unique identifier is composed of thirteen digits, of which the first two map to the Network Operator for the MPAN. The Proposer is therefore proposing that the DCC validate the Command that the Supplier Party issues place the Network Certificate on the ESME. Where the DCC knows which MPAN is assigned to the ESME, they can verify that the Certificate being placed in the Network Operator slot is for the Network Operator associated with that MPAN. Should the MPAN be unknown, DCC systems can revert to default functionality and trust that the Supplier Party is updating to the correct Certificate.
