SECMP0063 Ensuring correct Network Operator Certificates are placed on Electricity Smart Meters

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.

The DCC has noted the Proposer’s proposed solution was only applicable to Electricity Smart Metering Equipment (ESME) and not Gas Smart metering Equipment (GSME). The DCC has therefore proposed that the DCC Data System performs a new validation check when it receives the following Service Requests submitted by Energy Suppliers:

• SRV 6.15.1 ‘Update Security Credentials (KRP)’: Required only when it is targeted at an ESME
  
• SRV 6.21 ‘Request Handover of DCC Controlled Device’: Required for the target device types ESME and GPF
  

The validation checks will verify that the Network Operator Certificate included in the Service Request belongs to the Network Operator that is recorded in the Data Service Provider’s copy of Registration data and therefore the responsible Network Operator for the MPAN or MPRN associated with the target Device. This provides a common and standard solution for both ESME and Gas Proxy Function (GPF) Devices.
