The key components of a consumer interface

A local port on the smart meter enabling consumer secured access to useful meter data

An interface compliant to M441

A compatibility with DLMS COSEM

The choice of the data to push

A data push with high dynamic

Direct or via external adapter

A secured interface

A cheap interface

In either case the data model and protocol is the same: DLMS/COSEM

The complete data set of the smart meter could be sent to the CII if desired

Optical port (EN62056-21) – lowest costM-Bus port (EN13757-2) – adds access to power

PUSH scheduler are configured with different sets of data

Provides direct access or via external dongle. Powered, polarity independent, high level of physical protection

AES 128 GCM dedicated key (CIP keys), managed by the HES. HES can also turn off the port

The M-Bus interface is a simple 2 wires interface widely used in metering, with low cost of implementation

The IDIS Association supports rigorous 3rd

party interoperability testing to ensure

high quality standards.

IDIS association members are currently

Landis+Gyr, Itron, Iskraemeco, and Elster

What is IDIS?

The IDIS Association develops, maintains

and promotes publicly available technical

interoperability specifications (“IDIS

Specifications”) completely based on

open standards and supports their

implementation in interoperable

products.

The IDIS specifications are completely

based on existing standards. In order to

ensure true interoperability between the

IDIS devices the IDIS specifications define

specific choices of the different options

offered by those open standards.

What is the IDIS Consumer Information Interface?

Consumer Information Interface CII

A local port on the smart meter enabling consumer access to useful meter data The local port may be any serial port on the meter

15

Consumer Information Push CIP

Use of the IDIS PUSH concept to export (PUSH) DLMS/COSEM formatted smart meter data from the meter (server) to the CII

Any smart meter data may be assigned to the CIP PUSH scheduler though in practice only a subset of the meter’s DLMS data set is likely to be used

The CIP connection is unidirectional from meter server to CII client The data from the meter pushed to the CII (via CIP) may be secured If it is secured, then the security material used for this Meter->CII->Consumer Equipment

communication is independent of the security material used for the remote Meter<->HES communication.

The keys (CIP keys) used for the data pushed to the CII are managed by the HES.

The Landis+Gyr CII implementation

The IDIS CII can be manifest at any serial port of the meter

Optical port (EN62056-21) – lowest possible cost to the utility

M-Bus port (EN13757-2) – adds access to power

In either case the data model and protocol is the same –DLMS/COSEM

16

The CII data model is flexible

The complete data set of the smart meter could be sent to the CII if desired

In practice a series of PUSH schedulers will be configured in the meter by the HES to determine:– The actual data to be pushed– The frequency these data items are to

be pushed at– E.g. active import/export power and

energy every few seconds; daily billing profile only every few hours

Security and privacy

Security and privacy model

1. Keys used to secure the CII are generated in the HES and

a) sent to the meter andb) sent ‘out of band’ to the consumer

2. The consumer by ‘whatever means’ adds this key to the consumer HAN device to be connected to the CII

3. The unidirectional CIP->CII is secured

17

o ‘whatever means’ is out of scope for Landis+Gyr and is in the domain of the consumer HAN device provider

Physical implementation

Physical aspects of the CII

IDIS CII over 62056-21– Simple export of data over the optical port– No new HW in the meter requiring utility

investment– All HAN functionalities and liabilities are

clearly with the consumer

IDIS CII over EN13575-2 bus – M-BUS EN13575-2 well established in

metering– provides power; polarity independent– high level of physical protection for meter

and client devices– easy and cheap installation (if the utility

have to do it…)– Split utility/consumer access to the M-Bus

terminals if required as per example here

18

For illustration only

M-Bus terminals remaining under a utility seal for the purpose of multi-

Summary

The IDIS Consumer Information Interface:

Applies standards Maintains smart meter security and delivers consumer privacy Is designed to be as simple as possible Enables configurable local access to meter data

The IDIS CII can be manifest at any serial port of the meter

Optical port (EN62056-21) – lowest possible cost to the utility M-Bus port (EN13757-2) – adds access to power

The IDIS CII establishes the foundation for ANY future consumer HAN services outside the meter
