           Smart Card in GSM

Every GSM and UMTS phone contains a smart card
(SIM or USIM):
  Provides secure strorage for sensitive information
  Manages identity and network access information necessary
  for authentication and billing
  Stores phone numbers and short messages
  Facilitates roaming, storage of preferred roaming networks
  Enables VAS and m-commerce
  SIM-handset interface well standardised




                                                               3
 SIM based Value-Added-Services

Operators are facing tough competition:
   MVNOs, price wars, number portability
    -> CHURN

SIM application toolkit (SAT):
   SIM resident SAT application to access additional services:
       Easy access through SAT menu
       SAT enhances handset features
    -> CUSTOMER LOYALTY
       Entertainment                   Information
        Shopping                           Games
      Internet access                   Banking
                                                                 4
           Toolkit Applications

SAT applications are not well standardised:
  Operator requirements
  Proprietary implementations

Some industry standards/specifications, off-the-shelf
applications:
  SmartTrust WIB browser:
      Certification process to ensure interoperability
  SIMalliance S@T browser
  WIM                                                     My

       Native OS vs. Java Card

Proprietary SAT platforms:
  Based on closed operating system and SAT platform
  Steep learning curve
  Applications re-developed for each platform
  Differences in file and application management

'Open' Java Card OS:
  Standardised OS and SAT APIs
  Easy to learn
  "Write once, run anywhere"
  Standardised file and application management
   -> GlobalPlatform adopted
                                                      6

                Interoperability

Interoperability essential for operator to simplify and
speed-up toolkit development process:
   specify -> implement -> test -> introduce
       Long product development cycles used to be typical for
       SAT applications
   One application for all card platforms from different card
   vendors
   Uniform performance
   Flexibility in choosing the application management platform
   independent of the card vendor

Interoperability allows for managing the applications
anytime and anywhere
                                                                 8
                Interoperability

Differences in Java Card implementations:
   Internal memory management not standardised
   Loading and installing applets may differ
   Different performance due to hardware and OS implementation

Java SIM interoperability guidelines and tools from
SIMalliance:
   Applet execution interoperability
   Applet management interoperability

ETSI arranges Plugtests™ to verify interoperability:
   Cards, applets, tools, handsets

                                                             9
       Application Management

SAT application stored in the SIM during card
personalisation, operator may have needs to:
  Modify or remove applications
  Download new applications
  Modify the file system (update, remove files)
  Resize files (applications, data files)

Number of operators actively using SAT
  Mostly native or non-interoperable applications
  Testing Java Card interoperability

New opportunities for post-issuance:
  BIG cards >1MB:
     Shared platform for third-party application suppliers
  Bearer Independent Protocol, i.e. GPRS replacing SMS:
     Faster updating of cards
  Security and Trust Service API for J2ME (JSR177):
     Access to smart card services and applications from
     handset applications
