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.

Physical Parameters
Optical port – IEC62056-21 up to 19,200baud. M-Bus port - EN13757-2, rated at 6mA
(representing up to 4 slave load units each at 1.5mA), 12-24V, and 38,400baud.
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

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
