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

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

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

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

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

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 interface the multi-application platform USIM** = UMTS application on a UICC the application implementation * TS 102.221 owned by TC SCP ** TS 31.102 owned by 3GPP T3

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

From “Mono-" to Multi-Application 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 UICC WIM Ticketing EMV USIM SIM Electronic Purse Phonebook (U)SAT GSM Purse SIM SIM Application Toolkit (SAT) Banking Location Browser SIM-WIM

New Features of the USIM/UICC 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

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 cards based 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

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

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)

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

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

CAT_TP and BIP Server CAT_TP 03.48 security layer application protocol 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
