SIM Card Overview SIM Card Overview Presentation Transcript

  • SIM Cards Overview C. Enrique Ortiz | August 2009 http://weblog.cenriqueortiz.com © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • What is a SIM Card? • SIM or Subscriber Identification Module is a smart card that is included in every cell phone of the GSM family of networks 6 or 8-pin flat connector embedded on the top of the card A fully fledge microcomputer with an OS • UICC stands for Universal Integrated Circuit Card is a new generation SIM Source:3, Java Card 3: Classic Functionality Gets a Connectivity Boost © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • More on SIM and SIM Cards • SIM cards hold subscriber information and memory, for example for personal directory of numbers SIM identifies a subscriber via unique International Mobile Subscriber Identity (IMSI) >The first 3 digits represent the Mobile Country Code (MCC) >The next 2 digits represent the Mobile Network Code (MNC) >The next 10 digits represent the mobile station identification number • SIM is the application that runs on a SIM Card SIM is to GSM, what USIM is to UMTS & RUIM/CSIM is to CDMA • Today most SIM cards are based on Java Card © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • SIM and Smartcard Standards Standards for: •Toolkit •File & Auth •APIs •OTA •Smartcards ISO/IEC 14443 is the international standard for contactless smart chips and cards that operate (i.e., can be read from or written to) at a distance of less than 10 centimeters (4 inches). This standard operates at 13.56 MHz and includes specifications for the physical characteristics, radio frequency power and signal interface, initialization and anti-collision protocols and transmission protocol. ISO/IEC 7816 is the international standard for contact smart cards. ISO/IEC 7816 Parts 4 and Source: Gemalto above are used by both contact and contactless •ETSI -- Specifications in blue smart card applications for security operations •3GPP -- Specifications in green and red and commands for interchange. Source: Smart Card Alliance Java Card (classic or 3.0) Applets are built using Java and run in a JCRE © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Industry: Interesting Numbers for 2008 • Global SIM card shipments exceeded 2.9 billion units during 2008 Strong demand from the emerging markets of India, China, Asia Pacific and Latin America contributing to a 29 per cent increase on shipments over the previous year • On average, memory size increased by 11 per cent on 2007 figures • Number of cards shipped with a S@T (SIMalliance Toolkit) browser had a growth rate of 22 per cent • 3G enabled SIM cards represented 14 per cent of total shipments in 2008 Source:SIMalliance © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Next Generation SIM Cards • Next gen SIM Cards integrate with new functionality… • Mobile Near Field Communication (NFC) • More advanced Applications Address book, calendar back-up, messaging, teleconferencing and file transfers, banking and access control, Web! • Smart Card Web Server Web apps running right on SIM Cards! And TCP stacks • High-capacity SIM cards More and more memory/capacity • Multi-Media support (in conjunction w/ browser) © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Overview: Programming SIM Cards • SIM Toolkit Toolkit “conversation” between phone and Smartcard Source: Gemalto A SIM Toolkit is a data management application (applet) for SIM cards, part of which is resident in the SIM card •Icon, application, settings and help management •User (simple menus), mobile, network and card interactions © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Overview: Java Card Classic import javacard.framework.* ... public class MyApplet extends Applet { // Definitions of APDU-related instruction codes ... MyApplet() {...} // Constructor // Life-cycle methods install() {...} Source: Introduction to Java Card Technology by C. Enrique Ortiz select() {...} deselect() {...} process() {...} // Private methods ... } © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • SIM / Smart Card Application Communication Application Communication Architecture Response APDU Structure Source: SIM Protocols by Mobile Forensics Command APDU Structure © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Classical Java Card Development IDEs can simplify these steps! Source: Introduction to Java Card Technology by C. Enrique Ortiz © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Java Card 3.0 • Extends (and simplifies) the programming model • Classic Applets (Java Card 2 limitations apply for these applications) Communication using APDU protocol Backward compatibility • Extended Applets Communication using APDU protocol Similar to Classic Applets, and can use all the new APIs, like Threads, Strings, and GCF (Generic Connection Framework) • Web Enabled! Based on Servlet 2.4 API Communication using standard HTTP/ HTTPS protocol HTML, JavaScript, etc. (much richer UIs than prior) © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Java Card 3 Architecture Source -- Java Card 3: Classic Functionality Gets a Connectivity Boost by Peter Allenbach •All data types except float and double •Multiple threads NEW! •Extensive API support (java.lang, java.util, GCF, and so on) •Direct handling of class files, with all loading and linking on card •All new Java language syntax constructs (enums, generics, …) •Automatic garbage collection © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Smartcard Web Server • Very exciting and powerful SIM card evolution in my opinion! It took more than 10 years but we finally have it! Very powerful. • Leverages the browser already present in the handset to run local web applications preloaded into the SIM • Local web-based applications are securely stored in the SIM card and can be updated remotely Best of both worlds • Servlets framework on SIM Cards! Mobile SIM + Web Source: Gemalto Potential Apps: •Rich SIM card apps •On-Device Self-Service •Application Management •Mobile Payments Source: Gemalto •Mobile NFC © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Benefits of Smartcard Web Server • Rich UI and Advanced Capabilities Access to location, SMS, servers on the web, secure local-storage, personalized experience Call-intercepts to perform actions on-device, for example help troubleshoot issues before calling the support representative • Manageable Secure, remote application management • SIM-card based /On-Device Works Connected and Disconnected Secure connections and environment Uses no wireless resources when doing on-device web apps Access to information such as location that can help personalize the experience • Easy to deploy Highly customizable application; can be modified as needed and push to handsets in real-time Based on OMA and Web standards - xHTML, CSS, JavaScript © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
  • Some Challenges • SIM Card Applications still a niche, controlled by operators But if you have the relationships, it is a good niche ($) • Applet development is not trivial with few experts This can translate to opportunities for you! • Smartcard Web Server requires new generation SIM cards Thus conversion process will make adoption slow & expensive Expect emerging markets adopting first © 2009 C. Enrique Ortiz – http://CEnriqueOrtiz.com
