1. Multi-Application in Smart Card-based Devices Christophe Colas, ccolas@ingenico.fr Chief Software Architect August 2002

2. 2 Smart Card Systems Card Personalization / Issuance Back-end Systems Card Accepting Devices Post-Issuance Transactions (1) Post-Issuance Transactions (2) Smart Card

3. 3 Smart Card Systems (2) 3 Types of Processing Units Smart Card Card Accepting Devices (CADs) Back-end Systems Complete Application split into these Processing Units

4. 4 GlobalPlatform Key Focus Portability and Management of Applications across Smart Cards (Card Committee) Smart Card Management System (System Committee) Smart Card + Back-end Systems Portability and Management of Application across CADs (Device Committee) The remainder is strongly application specific…

6. 6 CAD Issues More and more Variety of Devices e.g. User Interface, Communication Devices are getting more Complex Multiplication of Development for Different Types of Platforms Longer Certification Process

7. 7 GlobalPlatform Device Objectives Reduce Development and Certification Cost Preserve Application Software Investments Offer independence from Hardware providers Enable easy addition of new services to final customers Facilitate secure remote maintenance in multi-application environment

8. 8 GlobalPlatform Device Committee Deliverables GlobalPlatform Device Framework (GPDF) 2.0 For Device Application Development Provides Application Architecture and APIs Based on Java technology Application Installation and Security

9. 9 GlobalPlatform Device Framework Based on STIP Technology Minimum Java Runtime Definition Basic Programming Pattern Basic Platform Service Definition e.g. smart card slot API, cryptography API, data storage API Multi-Application Environment Designed for Secure-based transactions Application Firewalling Controlled Access to Device Resources

10. 10 Application Portability Full Portability of a Complete Device Application for Different Types of Devices is impossible! e.g. User Interface or communication means are too much different Is possible only Portability of a module of the Application across several Types of Devices (the Invariant) Horizontal Interoperability GPDF CLC Concept Portability of the complete application for a given sets of device types Vertical Interoperability e.g. STIP EFT/POS Profile

11. 11 GPDF Application Architecture Application split into Platform and Environment-independent module Kernel of the application with Device Abstraction Contains Application Logic, which is Invariant to the Device and Environment = Core Logic Component (CLC) Portable across all Types of Devices (e.g. GSM phones, PDAs, EFT/POS terminals, Set-top boxes, …) Platform and Environment Module Customize the Kernel to the Device To the Environment (e.g. country, local rules, …) Mainly for User Interface and Communications

12. 12 GPDF 2.0 Architecture Business Logic Layer Core Logic Layer Environment Layer STIP Technology Core Framework Basic Device Services GPDF Platform CLC Module User Interface Communi- cation … Device Application Event Engine Storage Crypto- graphy Smart Card Reader … Java Virtual Machine Other Technologies Device Abstraction Services

13. 13 Device Application Secure Provisioning Distribution Format Security at the Distribution Level Authenticity and Integrity Association with Platform Service Access Rights Work in progress with GlobalPlatform and STIP Draft in Fall 2002

14. 14 Ingenico Commitment To Open Technologies Since 1998, Ingenico is working on standardization of open and interoperable technologies and focused at first on terminal environment Founding member and active participation in consortiums Java Environment Development for Secure Devices with small memory footprint FINREAD Embedded FINREAD

15. 15 Ingenico Products New 32-bit Terminal Family supporting Open Platform Technologies Open Platform components Embedded JVM supporting JEFF ISO Standard JEFF is a highly optimized Java executable format for embedded systems to reduce memory footprint STIP 2.1, GPDF 2.0 and FINREAD INGEODE INGEnico Open Development Environment
