Electronic Registration Identification (ERI) Concept, architecture and current status Murcia, 18th June 2009
Overview The ERI standard User requirements Architecture Current status 2 Electronic Registration Identification (ERI) 18 juni 2009
The ERI standard: Scope ISO/TS 24524 Electronic Registration Identification (ERI) A standard for identifying vehicles by electronic means Suitable for: Identification of local and foreign vehicles by authorities Vehicle manufacturing, vehicle life cycle management Safety related purposes Crime reduction Commercial services Adhering to privacy/data protection regulations 3 Electronic Registration Identification (ERI) 18 juni 2009
The ERI standard: History A CEN and ISO standard (part 5 is ISO only) A basic variant: Basis ERI Work started in spring 2003 Participants from: US, Mexico, Japan, several EU countries 2004: Expert opinions security & feasibility Currently a Technical Specification (TS) In transition to an International Standard (IS) unanimous positive vote in June 4 Electronic Registration Identification (ERI) 18 juni 2009
The ERI standard: 5 parts and Basic ERI 24534-1: Architecture 24534-2: Operational Requirements 24535: Basic ERI 24534-3: Vehicle data 24534-4: Secure communications Using asymmetrical techniques Basic ERI : allows for proprietary security implementations Part 4: Security may vary from very modest to highly secure Part 5: Used in Japan 24534-5: Secure communications Using symmetrical techniques Focus on application layer communication, lower layers are only referenced 5 Electronic Registration Identification (ERI) 18 juni 2009
User requirements: Identification Two types of identification: Specific vehicle identification Vehicle vicinity identification Safe, no hindrance to the driver Mandatory: no due diligence assumed Under all traffic and whether conditions Irrespective of the vehicle s speed Readable with roadside, mobile & handheld equipment 6 Electronic Registration Identification (ERI) 18 juni 2009
User requirements: Security Adaptable to user needs from very modest to highly secure Identification usable as legal evidence Authenticity (as needed) Is the ERT attached to the right vehicle Is it a genuine (not a fake) ERT ERT inoperable when removed Confidentiality (to the roadside) (as needed) privacy and protection against attack Read authorisation of authorities / third parties Support of international vehicle sales ERT key management / diversification 7 Electronic Registration Identification (ERI) 18 juni 2009
User requirements: ERI data Vehicle Id Vehicle Identification Number VIN (ISO 3779) Or, registration authority specific (WMI + e.g. a chassis number) Additional ERI data (optional) More then 60 different items E.g. vehicle registration certificate data Registration authority specific data 8 Electronic Registration Identification (ERI) 18 juni 2009
ERI: Architecture Overview: Basics Overall system concept The ERI system Two board variants In-vehicle architecture 9 Electronic Registration Identification (ERI) 18 juni 2009
Architecture: Basics For an acquirer: Architecture = Procurement policy! Only distinguish components if more than one party will be involved, i.e.: Different suppliers / maintenance companies Different owners / users do not specify internal details /interfaces Focus on behaviour / interfaces: Vehicle road-side (the main interface) In-vehicle (to support other onboard applications & architectures) ERI part 4 defines complete interfaces 10 Electronic Registration Identification (ERI) 18 juni 2009
Architecture: Overall system concept Vehicle Reader (writer) (Registration) authority Road Road-side (garage) Back office 11 Electronic Registration Identification (ERI) 18 juni 2009
Architecture: The ERI system ERI system ERT ERI reader/ writer Sensor system Onboard Non-ERI equipment ERI back office system E.g. a (registration) authority Vehicle 12 Electronic Registration Identification (ERI) 18 juni 2009
Architecture: Two onboard variants One single onboard component: ERT + DSRC tag Multiple onboard components: ERT ERR Other DSRC application module Onboard communication DSRC beacon ERI readers or readers/writers (ERRs) DSRC beacon Vehicle Road side 13 Electronic Registration Identification (ERI) 18 juni 2009
Architecture: In-vehicle architecture ERI standard interface ERI standard interface ERI Device Inductive coupling Internal reader /writer Other In vehicle device In vehicle communication Comm. device Air Interface e.g. ISO 14443 e.g. ISO 15628 / CEN 12834 14 Electronic Registration Identification (ERI) 18 juni 2009
Architecture: The ERT life cycle Customisation to a vehicle Writing vehicle data into the ERT Commissioning by a registration authority (RA) who may: assigns himself as the vehicle s RA enable / disable signing / encryption capabilities allow others to access ERT data Deployment, i.e. customised and commissioned Withdrawn (customised with revoked commissioning) 15 Electronic Registration Identification (ERI) 18 juni 2009
Current status ERI standard: Last steps in transition from TS to IS In the Netherlands: a TNO RDW project (see e.g. www.tno.nl) For 2 use cases: The inspector Rush hour avoidance Proprietary environment (=> secret keys) Multiple tags per vehicle to prevent identity fraud 16 Electronic Registration Identification (ERI) 18 juni 2009
In summary The ERI standard TS 24534 with part 4: Defines a complete interface with the OBE Allows a variety of onboard architectures Security is adaptable to user needs 17 Electronic Registration Identification (ERI) 18 juni 2009
