3 Status Home Energy Management. Home Initiative (HGI). HGI has published a document Use Cases and Architecture for a Home Energy Management Service (HGI-GD017-R3) after several workshops with other industry consortia and standardization groups. The generic architecture suggests the collocation of Home and Energy, categorizes different HN areas and defines logical interfaces. Several interfaces being considered such as Zigbee, Z-wave, DECT, Homeplug, G.hn, Wi-Fi, and others. HGI is introducing applications (home energy management, also health, security, automation) in the home that interact with IP and non-ip devices. HGI has defined an execution environment incl. a first set of standardized APIs ( HG Requirements for Software Execution Environment HGI-RD008-R3). Home Energy Management logic (and other application logic) can run (and interact) on the Home in combination with cloud based functions. 26/10/2011 3

5 Requirements by Federal Office of Information Security (BSI). Protection Profile Meter. Introduction of Protection Profiles for the components of a Metering System required in the EU Member States. German Federal Ministry of Economics and Technology mandated German Federal Office for Information Security (BSI) to develop a Protection Profile for the Meter. Protection Profile for the Target of Evaluation describes threats concerning security and privacy, defines requirements for countermeasures. Products will be certified based on the Protection Profile. German Regulatory Agency (BNetzA), Federal Metrology Institute (PTB), and professional organizations were involved in the development of the Protection Profile. Final draft Protection Profile for the of a Metering System v recently issued. 26/10/2011 5

6 Requirements by Federal Office for Information Security (BSI). Protection Profile Meter (continued). The shall offer a user interface to the HAN that allows CLS or consumers to connect to the in order to read relevant information. WAN Authorized ext. entity Meter LMN Meter Meter HAN = Home Area Network LMN = Local Metrological Network CLS = Controllable Local System e.g. white goods, air con, solar plant CLS HAN CLS Consumer 26/10/2011 6

7 Requirements by Federal Office for Information Security (BSI). Functional Requirements. Technical Guideline TR for the operation of a Metering system under development. Requirements for the interoperability of a Metering system comprising the elements that are certified by the Protection Profile. First draft presented on 14th October, next meeting in December. Document expected to be issued by April /10/2011 7

8 Communication Concept Proposal. (1/4) Differentiation between Critical Infrastructure Energy Domain and Customer Domain because of different security profiles. No direct physical connection between those two domains. Customer access via web services over Internet. Local unidirectional wireless meter readout possible, SRD band (Short Range Devices). If appliances in the resident s premises are connected to a managed service (e.g. time shifted power connection of white goods), there shall be no possible interference from that appliance to the service in general. Both domains follow different roll-out speed and logic. Market communication of the utility business is another independent domain. 26/10/2011 8

11 Communication Concept Proposal. (4/4) Propositions on Connectivity. Customer Domain Critical Infrastructure Energy Domain Customer has final control and responsibility Responsibility for successful delivery, fixed SLAs, possible contractual penalties Guarantee on the delivery of the service dependent Guarantee on undisturbed operation without danger on SLA, if managed of tampering, intrusion or service blocking Service dependant variable reliability level High to very high reliability level Service dependant variable security level Direct customer access to infrastructure possible Secure actor contact to start and stop decentralized generation Signature or authentication or encryption optional Signature & authentication & encryption mandatory Transfer time 10 s for command & alarm signals, Transfer time 2 s for command control, load 5 min for energy measuring, supply management shedding, peak shaving Connection/disconnection of single loads typically Connection/disconnection of single loads typically 3 kw (max. consumption household appliance) 100 kw (consumption of devices with net impact) 26/10/

12 Conformance of Proposal with BSI Requirements. Separation of Critical Infrastructure Energy Domain and Customer Domain. HAN access only via dedicated interfaces. HAN may have access to the Internet. Requirements regarding local unidirectional wireless meter readout between Meter in Critical Infrastructure Energy Domain and HA in Customer Domain not yet defined by BSI. 26/10/

13 Contributions to Standardization Work. Incorporated into draft ETSI Applicability of M2M architecture to Grid Networks Impact of Grids on M2M platform as Grid / Metering Customer Domain Use Case, Deployment Scenarios.

14 Conclusion. Differentiation between Critical Infrastructure Energy Domain and Customer Domain because of different security profiles. Both domains follow different roll-out speed and logic and belong to different control regimes although they are one Home Domain for the inhabitant. Local unidirectional wireless meter readout possible. Concept Proposal has been contributed to Standardization. 26/10/
