Approved Service - Service Description

This Public Service Description relates to Smart DCC Limited’s service known as SMKI Device Certification Authority (DCA).

The Smart Meter Key Infrastructure (SMKI) service is a Public Key Infrastructure service operated by Smart DCC Limited under a licence issued by the former Department of Energy and Climate Change (DECC), now the Department of Business, Energy and Industrial Strategy (BEIS), and is governed by the Smart Energy Code (SEC). The SMKI service will be used to control the creation, distribution and management of x.509 digital certificates to support the manufacture and roll-out of smart meters in the United Kingdom for the purposes of ensuring the authenticity, integrity, confidentiality and non-repudiation of communications and data passing between the smart meters and the business systems of energy suppliers, network operators and other authorised service users.

Within the overall SMKI, there are three tScheme approved Certificate Authorities, of which one is known as the SMKI Device Certification Authority (DCA). The others are the SMKI Organisation Certification Authority (OCA), and the Infrastructure Key Infrastructure Certification Authority (IKA CA, or ICA).

The issuance of device certificates by the DCA is governed by the DCA Certificate Policy (CP), which forms Appendix A to the SEC published on the Smart Energy Code Company website, and the associated Certificate Practice Statement (CPS) published to the SMKI Repository together with the tScheme Service Policy Disclosure Statement (SPDS). This Public Service Description section is published on the tScheme website.

To gain access to access to SMKI services and request device certificates either individually or in batches, the DCC, energy suppliers, network operators and other authorised service users will be required to complete the registration process that is detailed in the SEC Subsidiary document Appendix D, SMKI Registration Authority Process & Procedures (RAPP) and required to conform to the SMKI Code of Connection. All initial device certificate requests whether submitted individually or in batches are subject to approval by the SMKI Registration Authority (RA).

Device certificates are published by the DCA to the SMKI Repository upon issuance. Access to the SMKI Repository is governed by SMKI Repository Code of Connection.

Device certificates, once issued, cannot be revoked and no certificate status validation information is provided.
