 Coordinating security and privacy in smart grids
 Role of TISPAN
 Role of M2M
 Role of others
 Understanding of risk in smart grids
 From attack both accidental and malicious
 Understanding of personal data and privacy in smart grids
 Preservation of consumer privacy
 Resilience modelling
 Support to utility infrastructure
 Support to communications infrastructure

Coordinating security for smart grids in ETSI?
 TISPAN
 Ensuring the NGN is protected from, and provides protection for,
services and applications crossing or hosted in core NGNs
 Maintenance and guidance of the “design for assurance” paradigm
 Maintenance and guidance of the “privacy by design” paradigm
 Role of M2M and others
 Use cases, deployment modelling, protocol identification, validation
of core security and privacy models
 Extension to non-NGN and non-Core functionality consistent with
NGN and core functionality for local devices and their interfaces.

The NGN as a collection of provider entities

Security protection measures
 CIA paradigm
 Confidentiality
• Is information exchanged across the network only visible to those
authorised to see it?
• Covers encryption and separation technologies
 Integrity
• Has the information exchanged been altered in transit?
• Has the system itself been altered?
 Availability
• Covers a number of topics:
•
•
•
•
Identification (and validation of identity through authentication)
Authorisation (is Ann allowed to perform that function?)
Reliability
Resilience

Privacy protection measures
 ISO 15408-2 (Common Criteria) identifies 4 key attributes that
relate to privacy and which are undergoing assessment for
application in the NGN
 Anonymity
• Can a party transact anonymously?
 Pseudonymity
• Can a user mask themselves with an alias?
 Un-Linkability
• Does one provider need to know if another provider is offering services to
the same person?
 Un-Observability
• Does the provider need to ensure that a user may use a resource or
service without others, especially third parties, being able to observe that
the resource or service is being used?

Trust in the NGN
 How does the service trust the network?
 How does the content provider trust the service platform?
 Proposal being considered in TISPAN for the NGN
 Keyed authorisation framework
• Variant of X.509 based Privilege Management Infrastructure (PMI)
• Elements of Kerberos ticket granting service too
 Will fully support the LI requirements in the “Dynamic Triggering”
area
 May allow greater trust from users of the core network
 May act as a deterrent to SPAM, DDoS and other attacks

Explicit authorisation model
 Assertions
 Content providers require QoS, GoS guarantees
 Network resource is finite
 Detection and prevention of law breaking aids society
 Considerations
 Service providers want customer retention
 Users want privacy
 Users want freedom of expression
 Identification and authentication are not sufficient by themselves
in the NGN and our e-world
 Authorisation and privacy protection have to be added
Smart Grids Workshop 14 June 2010 - ETSI

Standardisation of authorisation frameworks
 TISPAN and ETSI
 Expand the models developed in TS 187 016 “TISPAN; NGN Security;
Identity protection (Protection Profile)” and apply them to generic and
specific NGN models
 Mandate them for the NGN core
 ENISA?
 Promotion and encouragement of development
 Others?
 For discussion – but everyone has a role they can play
