CAD

Consumer Access Device

A Consumer Access Device (CAD) is a cloud-connected secure smart meter gateway device that accesses real-time energy data from smart meters and sends that data to a designated cloud service. Real-time energy data can then be linked to other Internet of Things applications and connected home applications to unlock additional benefits for the consumer.

Gas Transporters develop, operate and maintain local gas transportation networks which transport gas from the North Sea and interconnectors to end consumer premises. They can help with queries such as moving meters, new gas connections and gas leaks.

HAN

Home Area Network

HAN means, for each Smart Metering System, the Home Area Network created by the Communications Hub Function. This forms part of the Smart Metering System with the other devices in the home (electricity and gas meters, in home displays and Prepayment Meter Interface Devices (PPMIDs).

IS

Import Supplier (DCC User Role)

Import Supplier, for a Smart Metering System or a device, is the energy supplier registered to supply electricity to an end consumer's electricity meter.

KRP

Known Remote Party

In the context of a specific device, a Remote Party whose security credentials are stored on that device in at least one trust anchor cell, and where a Remote Party is known to a device by way of that Remote Party’s Security Credentials being stored on the device (as specified in GBCS Section 4.3.2.5), the Remote Party is referred to as a Known Remote Party (KRP). Otherwise, it is referred to as an Unknown Remote Party (URP).

MPAN

The Smart Metering Wide Area Network (SM WAN) is the means by which the DCC sends, receives and conveys communications to and from Communications Hub Functions which are then passed on to the meters and other devices in the end consumer premises Home Area Networks.

SMIP

Smart Metering Implementation Programme

SMKI

Smart Metering Key Infrastructure

The Smart Metering Key Infrastructure (SMKI) is one of the primary mechanisms to secure communications between users and smart metering devices such as smart meters and communications hubs. It confirms that the SEC Party attempting to communicate with the devices is authorised to do so.

SREPT

SMKI & Repository Entry Process Testing

SMKI & Repository Entry Process Testing (SREPT) allows SEC Parties to become SEC Parties under the Organisation and Device Certificate Policies and eligible to access the SMKI Repository.

SRV
