PlaySIM Project Java One 2009 PlaySIM Project Java One 2009 Presentation Transcript

  • Project PlaySIM: Experimenting with Java Card™ 3 System Programming Eric Arseneau - Sun Sebastian Hans - Sun Fritjof Engelhardtsen - Telenor Steinar Brede - Telenor
  • What is PlaySIM?
    • Provide an open platform to experiment and innovate with Java Card 3.0 enabled SIM cards
    • Turn a Sun SPOT into a Java SIM card
    • NOT an emulator!!!
    • Telcos want new services and applications showcased before they commit
    • Expand the role of the SIM card in M2M domain
    • Project initiated by Telenor ASA with Sun
      • 7th largest mobile operator in the world
      • > 170M subscribers
  • Agenda
    • What is a SIM card ?
    • What is Java Card(TM) 3.0 ?
    • What is a Sun SPOT ?
    • What is PlaySIM ?
  • What is a SIM card?
    • Subscriber Identity Module (SIM) for mobile networks
    • Separates the user subscription from the terminal
    • User credentials, security data, address, sms, ...
    • Fully managed secure platform
    • Introduction of Java technology turned the SIM card into a multi application platform
    • In 2008 sold 3.2 Billion for Telcos
      • 2009 estimated at 3.6 Billion
  • Not JUST phones
  • Enables highly secure services
    • The SIM card is a secure connected service platform that you seldom leave behind
    • PKI based authentication, roaming management, ...
    • One time password generator for online banking
  • What we have today
    • SIM cards are based on ISO 7816 standards
      • Single threaded, master slave protocol
      • APDU max 255 bytes per message
      • Low speed, clock and power from the terminal
      • Slow EEPROM memory 32-128KB
      • RAM 8-16KB
      • SIM-Toolkit protocol to overcome the master-slave limitation of the ISO standards
        • Very specific to the Telco market
        • Difficult to use and to test
        • Needs a lot of GSM/UMTS domain knowledge
  • Java Card 2.x
    • Java Card 2.X has an over 10 year history
    • Defined for very constraint devices
      • < 512bytes of RAM
      • < 4KB non-volatile memory
    • Single threaded
    • Limited communication capabilities
    • No Strings, no int, no float, split VM
    • Over 6 Billion Java Card Devices
      • Most prolific Java platform to date
  • SIM card trends require more capabilities from software 16k 64k 256k 1Mb 1Gb SCWS NFC USB Multi tread IP stack Embedded short-range radios GPS Accelerometer Temperature ...
  • But we need to move ahead!
  • How to program these capabilities?
    • With these existing and new capabilities, how do we program these devices?
    • The SIM cards have been a very closed and proprietary environment
    • Java Card brings the write once run everywhere mantra to SIM cards
    • Java Card 3.x is the platform to use these new capabilities
    • 3 rd party applications and services could now be ported to different SIM cards
  • SIM Card IS the computer
    • This is a new way of thinking
    • Added computing capabilities, network integration, new sensors
    • Carriers get a viable platform that they control and are able to distribute new services more quickly
  • Java Card 3.x
    • Last year 3.0 was only the specification
    • Just released 3.0.1
      • http://java.sun.com/products/ javacard
      • Reference Implementation - Emulator
      • NetBeans Module
      • TCK
    • Classic Edition – Keeps 2.x compatibility
    • Connected Edition
  • Java Card 3 Connected Edition High Level Architecture
  • Java Card 3.0 main new Features
    • Multithreading, CLDC 1.1
    • Supports of multiple hardware and logical interfaces
    • Build in Servlet Engine, Servlets API 2.4
    • Strings, Annotations, Generics, TCP/IP Sockets, SSL/TLS, HTTP connections, GCF
    • Integrate Java Card 3.0 as a secure multi interface card platform into IP networks
    • Seamless secure connection with Browsers and Applications on the Terminal or in the Network
    • Card is a secure server in the local network
  • Some new ideas..
    • Telenor student interns loved to play with the SunSPOT platform and it is popular at the local university
    • Maybe we can leverage this enthusiasm to spur SIM card and service innovation?
  • What is a Sun SPOT?
    • Built to inspire
