Presentation Agenda Introduction What is Smart Card? Java Card Java Card Architecture Developing a Java Card Application Features Applications Advantages Limitations Conclusion
Introduction The first Java Card was introduced in 1996 by Schlumberge’s card division which later merged with Gemplus to form Gemalto Java Card refers to a technology that allows Java-based applications to be run securely on smart cards. Java Card gives the user, the ability to program the device and make them application specific. Java Card is a smart card that is capable of running programs written in Java.
Smart Cards A smart card is a plastic card that contains an embedded integrated circuit (IC) Examples: Our very Own T-Card! Credit Cards Cell Phone SIM Cards
Java Cards are Smart! How?? They store and process Information Smart Cards can be used to add authentication and secure access to information systems that require a high level of security
JAVA CARDWhat is a Java Card? Simple Answer: Java+Card=Java card Adoption of Java platform for usage on Smart cards . A programmable smart card A multi-application smart card A smart card for secure application loading
EVELOPING A JAVA CARD APPLET 1.Write the Java source 2.Compile your source 3.Convert the class files into a Converted Applet (CAP) file(Binary representation of Classes & interfaces) 4.Verify that the CAP is valid 5.Install the CAP file
Features of Java Card SUPPORTED NOT SUPPORTED • Small primitive data types: • Large primitive data types: boolean, byte, short. long, double, float. • Characters, strings. • One dimensional arrays. • Multidimensional arrays. • Object oriented features: • Dynamic class loading. inheritance, virtual • Garbage collection. methods, dynamic object • Threads. creation, overloading, • Object Cloning scope.
CONCLUSION•Java Card and other flavors of Java will open new markets•Java Card Technology defines a run time environment thatsupports the smart card memory, communication, security andapplication execution model.•Java Card Technology fits java system software in a smartcard while conserving enough space for applications.•Java Card mitigates some risks associated with Java such asdynamic class loading
