3 Project Technology Partners See Seite 3

4 Project Goal Development of an interoperable eticketing system based on handsets with a special NFC-enabled SIM Seite 4

5 Mobile based vs. "conventional" eticketing Handset + SIM Smart Card + Terminal Low Invest because of use of the existing infrastructure (GSM/UMTS) Good user interaction based on mobile phone GUI New Technology Difficult to check tickets authenticity Mature Technology already applied in several projects worldwide Approved security mechanisms Easy to control ticket High initial investment High TCO (Total Cost of Ownership) Bad user interaction Seite 5

6 Examples for Smart Card Ticketing Standards Scandinavia Handbook 206 RKF France Calypso influenced ISO14443 B Germany Several small projects based on ZKA DF-Fahrschein -> not interoperable VDV Kernapplikation (KA) > interoperable European standardization in progress (since 2000) pren 1545 ( Data elements for PT) -> Data elements IOPTA - Interoperable Transport Application (CEN TC24 WG 11 ) -> Interface, Security IFM - Interoperable Fare Management (CEN TC278 WG 3 ) ->Role model, organizational interoperability Seite 6

7 Mobile Ticketing Approaches SMS ticket (Ticket as SMS) Text based J2ME Ticket (Ticket in MIDlet) Simple text or barcode, security based on MIDlet NFC/J2ME ticket (RMV) MIDlet as smarcard BMBF project Ring & Ride (Route tracing using cell information) Security and addidtional functions provided by SIM Seite 7

8 BMBF Project Ring & Ride Fare calculation based on cell logging Seite 8

11 Touch&Travel front-end components NFC/SWP enabled SIM and Handset SIM based reading and authentication of Tags Cell logging necessary for fare calculation With VDV KA applet Acting as contactless card/reader (in conjunction with SIM) Communication with back end system Control Device Agnostic if contactless Smart Card or NFC Handset/SIM is checked CheckPoint supports fare calculation NFC Tags (in "Touchpoints") ISO14443-A compliant JavaCard based Tag with special T&T Applet Seite 11

12 System Usage CheckOut CheckIn (Frankfurt) Activation of the handsets reader mode Place handset in front of tag Ticket on SIM set to "checked in" by back-end Start of journey registered by back-end system During journey, cell information collected by SIM CheckOut (Potsdam) Activation of the handsets reader mode Place handset in front of tag Ticket on SIM set to "checked out" by backend End of journey registered by back-end system Transfer of cell list to backend CheckIn Fare calculation based on cell logging Seite 12

16 VDV Kernapplikation - History BMBF project from 2001 to 2005 Research Project Detailed list can be found under Project Goals Specification of an interoperable ticketing standard Integrated micro "payment" system (called Werteinheitenspeicher) Definition of automatic fare calculation mechanisms Current status Specification maintained by VDV KA GmbH & Co. KG Several national projects. Major projects VRR/VRS currently rolled out Seite 16

17 VDV Kernapplikation - Structure Specification roles common for PTAs Interfaces between actors Data- and workflows Datastructures used in organisational part (pren1545 compliant) Specification of Card, SAM and Terminal processes Role model Process definitions Organisational interfaces Data structures & elements Technical interface specification End-to-end security Technical platform Seite 17

18 T&T Extension for VDV KA KA Specification has to be extended for T&T: Specification of Tag Application (Java Card Applet) Extension of Card specification -> Authentication of tag Extension of SAM specification All extensions rely on existing KA security mechanisms. Extensions have no impact on security model of the existing specification! Seite 18

19 NFC (Near Field Communication) with SIM involvement SWP/HCI CLF RFID- Tag Advantages of a SIM based solution: Only one security module i.e. SIM is necessary The customer can change the mobile phone Remote SIM administration (OTA) is an established technology All technologies applied are standardized or currently in standardization to ensure market convergence Interfaces to SIM: Single Wire Protocol (SWP) is the low level transport protocol The Host Controller Interface (HCI) is the basis for offering contactless service used in eticketing/ epayment applications Seite 19
