  1. The Smart Card Platform Gaby Lenhart Project leader ETSI Technical Committee Smart Card Platform (TB SCP)

  2. ETSI Technical Committee Smart Card Platform • 16 Years of dedication and real-life experience • founded in March 2000 as the successor of SMG9, the SIM-people, who specified the most successful smart card application with currently more than 1 billion subscribers and +2 billion SIMs deployed • mission • to create a series of specifications for a smart card platform, based on real-life (outside) requirements, on which other committees can base their system specific work to achieve basic compatibility

  3. TC SCP Terms of Reference • to develop the physical and the logical IC card platform • to develop advanced security methods for applications such as financial transactions (“mobile commerce”) • to develop a card-side toolkit to allow the creation of terminal independent value added services • to develop supporting specifications and technical reports

  4. SCP Plenary SCP Requirement Group TC SCP Working Structure* SCP Technical Group *as of April 2006

  5. TC SCP - Who Does What • Plenary • strategy and other general topics • approval of requirements for technical solutions • approval of new work items and specifications/reports • approval of Change Requests (CRs) to specifications/reports • liaisons with other committees and organizations • Requirement Working Group • analysis of requirements coming from outside and inside SCP • elaboration of requirements for the technical work • development of requirement specifications • Technical Working Group • enhancements to the core platform specifications • development of the next generation UICC • use of PKI, security between applications on the card • secure messaging, administrative commands • Card Application Toolkit (CAT) • Application Programming Interfaces (APIs) • development of card interfaces

  6. From “Mono-" to Multi-Application To provide interoperability in a multi-application environment a split was made • in GSM (GERAN): SIM = physical card + “GSM application” (GSM 11.11) • in 3G (UMTS/UTRAN): UICC* = physical card and physical, logical interfacethe multi-application platform USIM** = UMTS application on a UICCthe application implementation * TS 102.221 owned by TC SCP ** TS 31.102 owned by 3GPP T3

  7. The UICC System USIM SIM TETRA TS 102 221 The multi-application platform* *Scope similar to EMV2000 as used by financial sector Additional commands, features, security, PKI ....... CDMA2000 GAIT

  8. The SIM - a "mono-application" card SIM according to GSM 11.11 applications based on SIM Application Toolkit WIM as exception(own command set and triggered by WAP browser) The UICC - the multi-application platform separation of layers and applications logical channels to run applications in parallel WIM Ticketing USIM EMV SIM Electronic Purse SIM-WIM Banking Location Browser (U)SAT SIM Application Toolkit (SAT) Phonebook SIM UICC GSM Purse From “Mono-" to Multi-Application

  9. Multi-application card Supports multiple applications which can run simultaneously using logical channels Powerful phonebook Store entries with e-mail, second name, groups Intelligent linking to the GSM application allows data sharing in a GSM phone USIM/UICC Mutual authentication Authentication and Key Agreement (AKA) involves authentication of the 3G network to the USIM as well New PIN protection concept Hierarchical PIN management Universal PIN, Application PIN, Local PIN New Features of the USIM/UICC

  10. Published (1) - The Platform • TS 102 221 Physical and logical characteristics of the card / terminal interface • the core specification which provides a multi-application platform with logical channels for smart cardsbased on this platform a smart card application can be defined for any system • specifies the lower layers of a smart card including the electrical and mechanical interface, the logical structure, the basic commands and the intrinsic security system Related test specification published as TS 102 230

  11. Published (2) - Core Documents • Administrative commands (TS 102 222) • allows standardized personalization and standardized remote administration, e.g. over-the-air (OTA) • Card Application Toolkit (TS 102 223 / 227) • based on the successful GSM specification "SIM Application Toolkit" which was stripped of all the GSM specific features • allows the card issuer to create value added services independent from the terminal • application writers benefit by using CAT for different systems Transport protocol for CAT applications between a UICC application and a remote entity to ensure acknowledgement, segmentation/fragmentation, retransmission of messages • ETSI numbering system for telecommunication application providers (TS 101 220) • the ETSI offering of managing Application Identifiers (AIDs) for UICC based applications

  12. Published (3) - Derivatives Generalization of well-known GSM specifications (GSM 03.48 Secure messaging; GSM 03.19 Java CardTM API) • Secure messaging • defines end-to-end (smart card to application server) secure messaging over a variety of bearers (e.g. enciphered and integrity protected messages between the smart card and a banking server) • TS 102 224 Security mechanisms for UICC based Applications • TS 102 225 Secured packet structure for UICC based applications • TS 102 226 Remote APDU Structure for UICC based Applications • Application Programming Interface (API) • allows applications to be developed independently of the underlying card operating system • TS 102 240 Application Programming Interface and Loader, Requirements • TS 102 241 Java CardTM Application Programming Interface for the UICC; Stage 2(Java CardTM 2.2)

  13. Published (4) - EMC Technical Reports on interference topics • Measurement of Electromagnetic Emission of SIM Cards (TR 102 151) • definition of a standard hardware equipment for electromagnetic measurements of smart cards and a common electromagnetic measurement procedure • Terminal - card interface; Considerations on robustness improvements (TR 102 242) • describes failure mechanisms that could potentially generate major operating issues between the terminal and the card, the countermeasures that should be applied within the current specifications and the enhancements that may further increase the interface robustness

  14. Published (5) - The Toolkit Transport Protocol • CAT_TP provides the following functionality as underlying layer for application protocols (TS 102 124 and TS 102 127) • reliability of the data communication (not necessarily security, security can be handled by an independent GSM 03.48 layer) • segmentation and concatenation of data • retransmission of messages • addressing for different physical bearers (GPRS uses IP, SMS uses telephone numbers, Bluetooth has its own addressing scheme...) • access to BIP channels (up to 8 channels may be open the same time) • possible multiplexing of BIP channels • standardised opening a BIP channel from the server side

  15. application protocol 03.48 security layer CAT_TP Server CAT_TP and BIP BIP* • * Mechanism originally specified by 3GPP T3 by which the ME provides the UICC with access to the data bearers supported by the ME and the network

  16. How Small Is Small? 3rd Form Factor (3FF) specification of a new smaller card size providing backward compatibilityi.e. to utilize the same silicon / device for both the current plug-in and the new card size. The new card size may enable the use of devices currently not feasible for Plug-in cards. Reduce Plug-in Cardfrom 15 x 25 mm to 15 x 16.3 mm (375 mm2 to 244.5 mm2) 12 x 13 mm 8 x 8 mm

  17. IC Card 16.3 15 Plug-in Card Mini Plug-in Card The New Mini UICC Too big The solution: 12 mm x 15 mm

  18. Co-operation • SCP is co-operating on both technical and service aspects with a number of other committees both within and outside the telecommunications sector. These include 3GPP (UTRAN/GERAN), 3GPP2 (CDMA2000), ARIB and some ETSI Technical Bodies • provision of requirements, referencing SCP specifications GSMAssociaton (GSMA SCaG and GSMNA) • provision and alignment of requirements GlobalPlatform • close co-operation in the advancement of, in particular, OTA specifications • all specifications updated to and aligned with GlobalPlatform 2.1 Liberty Alliance • close co-operation on identity issues Open Mobile Alliance (OMA) • connectivity to the Smart Card Web Server, developed in OMA • close co-operation regarding Digital Rights Management (DRM) … and many others

  19. Current Topics (1) • High speed interface • evolution of the smart card communication channel with respect to transfer rate, size and protocol considering issues such as: • performance and power consumption • value to applications and scalability • to allow for large memory on the USIM • ease of implementation (in both terminal and UICC) • candidates • MMC (Multi Media Card protocol) • USB (Universal Serial Bus) To be finalized soon • UICC external peripherals data-exchange (near field communication • providing an interface for the UICC to access contactless technology in the terminal, which would allow e.g. for: • communicating patient data • accessing public transport • micro-payments using an electronic purse on the UICC

  20. Current Topics (2) • Support for Large Files on the UICC • Multimedia and PKI applications among others need to exceed the current maximum file size of 65,535 bytes. The aim is to increase the maximum file size beyond this limit providing backward compatibility (for existing implementations) • Environmental conditions • temperature range and humidity • vibration and acceleration shocks To be finalized soon • Sensitive data creation and initialization • The USSM (UICC Security Service Module) • container for security related topics such as keys, certificates, PINs and management of algorithms utilized by UICC based applications

  21. The Future - UICC ng The scope of the “next generation” Work Item includes: • possible role of memory management units • 32-bit processors and ASIC co-processors • proof-carrying code • new memory architectures • multi-tasking operating systems • embedded electrical sources • alternative form factors (not restricted by backward compatibility) • free-running oscillators on the chip • integrated biometric sensors, universal byte codes, new chip carriers, and high-speed communication channels
