3 EUROPA: ENERGY SAVING IS THE FIRST ANSWER TO CLIMATE CHANGE 20% less CO 2 20% renewable energy 20% less energy consumption Germany 2007: The 8 biggest municipal companies (8KU) demanded the development of an interoperable, producer and medium independent communication system for meter read out. 3

4 2007 FOUNDING OMS GROUP Founders The first action was system selection OMS = Open Metering System interoperable producer independent media independent and others 4

5 OMS members*) *) Oct 2015

6 OMS members The OMS-Group has 52 members from 12 countries (status Oct 2015) Producer of meters Producer of communication technology Service provider Utilities (DSO) members Since additional China 6

10 Open Metering System: All meters speaks the same language Metering Submetering

11 Housing assocoations OMS connects four sectors energy management EN50001 Industry energy monitoring, energy on demand Metering Utilities Submetering Energy consumption Home- and building automation, Information systems Energy consumption, Home control, Ambient assisted living

12 The OMS Specification Generation 1 (published 2009): wireless M-Bus 868MHz, S-, T-Mode, unidirectional meters Generation 2 (published 2009): wireless M-Bus 868MHz, S-, T-Mode, uni- and bidirectional meters without electricity meters >6 MWh/a Generation 3 (published 2011): wireless M-Bus 868MHz, S-, T-Mode, uni- and bidirectional meters with battery powered repeater and security (without BSI security for Germany) Generation 3 12

13 The OMS Specification Generation 4 (published 2014) Uni- & bi directional meters wired and wireless M-Bus 868 MHz C-, S-, T-Mode BSI security profiles for Germany In annexes national conditions other frequencies (433MHz) wired M-Bus Generation 4 13

14 The OMS Specification (Generation 4) After launching OMS Specification Generation 4 we see growing interests in European countries Germany: mandatory for local metrological network, Luxembourg: countrywide deployment of smart electricity, gas and water metering Belgium: strong interests 14

15 The OMS Specification is a freely accessible, has applicable protocols without any limitation can used without mandatory membership or other cost/limitation. is freely download from the website 15

17 Security in OMS Generation 3 Generation 4 Application Layer APL APL Security Profile A Profile B Profile C (basic meter) (soph. meter) No Security Data Link Layer DLL DLL DLL Physical Layer S-Mode T-Mode C-Mode Wired wireless

18 Security in OMS Profile Encryption Authentication Key No Security Profile No encryption (ENC-Mode 0) No MAC (MAC-Mode AT=00b; ATO=00b) No key for wired M-Bus Security profile A AES128-CBC (ENC-Mode 5) No MAC (MAC-Mode AT=00b; ATO=00b) 128 bit static symmetric key Security Profile B AES128-CBC (ENC-Mode 7) CMAC (8 Byte trunc.) (MAC-Mode AT=01b; ATO=01b) 128 bit dynamic symmetric key (derived by KDF) Security Profile C TLS 1.2 (ENC-Mode 13) HMAC (TLS1.2) and additional CMAC (8 Byte trunc.) (MAC-Mode AT=01b; ATO=01b) for communication establishment. 256 bit elliptic curve key (384 bit optional) for TLS and 128 bit dynamic symmetric key (derived by KDF) for CMAC Die Security profiles A und B can be realized with todays systems without extra hardware costs. OMS certified devices with security Profiles B or C guaranteed highest security requirements of the common criteria of German Federal Office for Information Security 18

25 The next tasks o Defining of the test specification for certifying bi- directional devices o Firmware update via wireless or wired communication system (done, already established in EU standards) o Controlling of external devices (e.g. valve for gas meter) o Specification adoption for national specialties o Marketing activities in European countries 25

26 Members are welcome oyou have access to internal documents oyou can influence the strategy of the OMS Group oyou can support the development of the OMS Group by participate in WG1 primary communication (wireless) WG3 test and certification WG4 primary communication (wired) WG5 marketing oyou can exchange information and experiences with other OMS Group members

27 Thank you for your attention Open Metering System Group Dr. Werner Domschke speaker of the board
