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

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

USIM** = UMTS application on a UICCthe application implementation

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

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)

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

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

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 shocksTo 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
