The following referenced documents are not necessary for the application of the present document but they assist the user with regard to a particular subject area. i.1 Department of Energy and EU Dir

20、ective 2002/58/EC i.15 on processing of personal data and the protection of privacy in the electronic communications sector. According to the commission recommendation of 9thMarch 2012 on preparation for the roll-out of smart metering systems, these two directives are “fully applicable to smart mete

21、ring which processes personal data, in particular in the use of publicly available electronic communications services for contractual and commercial relations with customers“. This recommendation provides further guidance on how the directives should apply to the smart metering systems. Other direct

22、ives that impact security and privacy are the following: Directive 2009/136/EC amending Directive 2002/22/EC on universal service and users rights relating to electronic communications networks and services i.16 Directive 2006/24/EC on the retention of data generated or processed in connection with

23、the provision of publicly available electronic communications services or of public communications networks i.17 Directive 1999/93/EC on a Community framework for electronic signatures i.18 Council directive 2008/114/EC of 8 December 2008 on the identification and designation of European critical in

25、C i.20 4.2 France 4.2.1 Data Security Rules The Data security offered by products or information systems may be certified as provided in the Decree #2002-535 of 18thApril 2002. ANSSI (French Network and Information Security Agency) is responsible for approving assessment centers and give an opinion

26、on the certification of systems. Certification is given by the Prime Minister following their assessment by approved centers. Concerning the electricity metering, the order of 4thJanuary 2012 requires system operators to have their metering system certified under Decree #2002-535 of 18thApril 2002.

27、This certification implies compliance with a security referential specified by ANSSI. ETSI ETSI TR 103 118 V1.1.1 (2015-08) 104.2.2 Privacy Protection Rules The Commission nationale de linformatique et des liberts (CNIL) is responsible for ensuring that information technology remains at the service

28、of citizens, and does not jeopardize human identity or breach human rights, privacy or individual or public liberties. The automated processing of personal data is subject to a prior declaration to CNIL. Specifically regarding Smart Metring Systems, Decree #2001-630 of 16thJuly 2001 (Decree #2004-18

29、3 of 18thFebruary 2004 for gas) requires system operators to keep confidential commercially sensitive data (information whose disclosure could undermine the rules of free and fair competition and non-discrimination). Metering data are commercially sensitive. In its resolution #2012-404 of 15thNovemb

30、er 2012, CNIL issued recommendations primarily on data collected (consent and limiting load curve sampling period), the duration of data retention (no conservation beyond the time required) the recipients of the data (habilitation) and security measures (assessment and regular updating). 4.3 Germany

31、 In Germany, legal and regulatory requirements are already in force for energy- and telecommunication enterprises. New legal requirements are in preparation for other critical infrastructures like finance, transport, food industry and health services. The new laws explicitly define critical infrastr

32、uctures and the obligation to prove that these infrastructures are operated securely. This has to be done by certified procedures and properly documented, i.e.by an Information Security management system like the ISO/IEC 27000 series i.21. Notification of security incidents to the authorities will b

33、e mandatory. In the legal framework of energy regulations, the metering service is a market driven business like the energy supply. Actually, the metering services are still done by the DSOs (Distribution System Operators). There are about 900 DSOs for electricity and about 700 DSOs for gas. But, be

34、sides of pilot projects, the roll-out of smart meters has not started yet. According to the Energy Industry Act (EnWG) the installation of smart meters and smart meter gateways is mandatory for consumers with an annual consumption of more than 6 000 kWh. The Ministry of Economics and Energy mandated

35、 the Federal Office for Information Security (BSI) to issue specifications for a smart meter gateway in order to meet concerns about privacy raised by the Federal Commissioner for Data Protection and Freedom of Information. These smart meters and gateways have to fulfil security requirements like Co

36、mmon Criteria Protection Profile and a Technical Specification to ensure interoperability between different metering Service Providers. These specifications are: Protection Profile for the Gateway of a Smart Metering System (BSI-CC-PP-0073) i.2 Protection Profile for the Security Module of a Smart M

37、eter Gateway (BSI-CC-PP-0077) i.2 Technische Richtlinie / Technical Guideline (BSI TR-03109) i.3 where the BSI TR-03109 is a collection of documents (only in German) specifying data formats, protocol stacks for WAN and metering communication, administration requirements and Public Key Infrastructure

38、. The German DKE group AK461.0.143 has specified the protection at the interface between the Smart Meter Gateway (SMGW) and the WAN or external entity. The specification is part of BSI TR-03109-1 i.3. ETSI ETSI TR 103 118 V1.1.1 (2015-08) 11Only outgoing connections from the SMGW to the external ent

39、ity are allowed. The SMGW is the TLS client, whereas the external entity is TLS server. Initiation with ECDSA signed wakeup from Administrator is optional. http(s) and additional content protection with CMS (based on PKCS#7) are used: first encrypted and authenticated, than signed. The external enti

40、ty can replace the signature for pseudonymization reasons. Mutual X.509 PKI authentication is required, no http authentication. The certificate types are: TLS (SMGW, administrator, other external entities); SubCA (e.g. administrator); RootCA+LinkCertificate; Content signature (SMGW, Admin); Content

41、encryption (SMGW, Admin, external entities); etc. The exposed resources according to a RESTful access concept are based on certificate authentication. Current TLS parameters for WAN: TLS1.2 (IETF RFC 5246 i.22); Cyphersuites min ECDHE_AES128_CBC_SHA256 and ECDHE_AES128_GCM_SHA256 transition to AES25

42、6 and SHA384 later; Using X.509 PKI certificates. ECDSABrainpoolP256r1 Signed, SHA256; ECC Curves, BrainpoolP256, NISTP384, BrainpoolP384, BrainpoolP512. Only with NamedCurveIDs (IETF RFC 7027 i.23); No session resumption, but session resume (max. session lifetime 2 days); Preference for Encrypt-tha

43、n-MAC indicated, no Truncated HMAC (to be updated in 2015). In 2013, a metering system ordinance (Messsystemverordnung), which refers to the BSI specifications was drafted by the German government and notified according to the “Directive 98/34/EC of the EUROPEAN PARLIAMENT and of the COUNCIL“ i.24,

44、which is laying down a procedure for the provision of information in the field of technical standards and regulations. Up to now, smart meters and gateways, which are compliant with the German legal and regulatory requirements are not available for a roll-out. The stakeholders are still waiting for

45、additional ordinances. The missing ordinances for the energy sector to clarify the obligations and scale of roll-out and the allocation of the costs are expected for mid-2015. 4.4 Netherlands An initial project law to impose mandatory roll-out of smart meters in the Netherlands was turned down in th

46、e Dutch Parliament in 2009 due to consumer concerns, which triggered serious actions from the Dutch DSOs to enhance consumers trust. Their association, Netbeheer Netherlands, enforces a code of conduct for the processing of personal data by Grid Operators and made a study on the Security and Privacy

47、 of Smart Metering that served as a basis to develop the security aspects of the Dutch Smart Metering Requirements (DSMR) specification i.4, which have already been iterated several times. The most important rules in the Netherlands for recording and using personal data have been set forth in the We

48、t bescherming persoonsgegevens (Wbp; Dutch Personal Data Protection Act). This act was unanimously adopted by the Dutch Senate on 23 November 1999 and accepted by the Dutch Congress on 3 July 2000. The act came into force on 1 September 2001. The Wbp relates to every use - processing - of personal d

49、ata, from the collection of these data up to and including the destruction of personal data. Smart meters in the Netherlands are the property of Grid operator. Almost 1 million smart meters have been installed during the first phase of roll-out until 2014. In 2015, the Grid operators start with the large-scale roll-out. 12 million gas and electrical smart meters are expected to be installed by 2020.
