1.2 Introduction

Java Card technology enables secure elements, such as smart cards and other tamper-resistant security chips to host applications called applets, which employ Java technology.

Java Card technology offers a secure and interoperable execution platform that can store and update multiple applications on a single resource constrained device, while retaining the highest certification levels and compatibility with standards. Java Card developers can build, test, and deploy applications and services rapidly and securely. This accelerated process reduces development costs, increases product differentiation, and enhances value to the customers.

The Java Card Development Kit is a suite of tools for designing implementations of Java Card technology and developing applets based on the Java Card Specifications. It is available as two independent downloads:

  • The Java Card Development Kit Tools are used to convert and verify Java Card applications.
  • The Java Card Development Kit Simulator offers a testing and debugging reference for Java Card applications. It includes a Java Card simulation environment and Eclipse plug-in.

Together, these two downloads provide a complete, stand-alone development environment in which applications written for the Java Card platform can be developed and tested.

These release notes describe the Java Card Development Kit Simulator version 3.1.0u5, which is based on version 3.1 of the Java Card Platform Specifications.

1.3 What's New

The following are the new features, changes, and bug fixes in the Java Card Development Kit Simulator, version 3.1.0u5:

  • Fixes to setKey() and getKey() methods of HMACKey and GenericSecretKey as per the clarifications provided in the specification.

The following are the new features, changes, and bug fixes in the Java Card Development Kit Simulator, version 3.1.0u4:

  • Added the usage of the target platform when the CAP file verification is done in Eclipse plugin projects
  • Added the usage of the target platform when CAP file verification is done for building the samples using the Ant tool
  • Fixes in HMAC implementation and handling of APDU case 4 in the APDU tool

The following are the new features, changes, and bug fixes in the Java Card Development Kit Simulator, version 3.1.0u3:

  • Fixed an installer issue when loading multiple applet and library CAP files with static resources
  • Fixed a minor issue in the ByteBuffer.slice method

The following are new features and changes in the Java Card Development Kit Simulator, version 3.1.0u1:

  • The Java Card plugin for Eclipse now supports all features of the latest Java Card Development Kit Tools and usability improvements for their integration. New features include:
    • Support for extended CAP files
    • Support for static resources in CAP files
    • Support the target parameter of the converter for the following versions of the Java Card Platform Specifications: 3.0.4, 3.0.5, and 3.1.0
    • New and improved management of CAP file configurations and the build process
    • Persistence of CAP file configurations in files that can be directly used by the converter tool in the command line
    • Support for Java Card Development Kit Tools path configuration as an independent setting. This ensures that the plug-in can always be configured to access the latest tools bundle.
    • Support for Java Card framework API debugging (source bundles only)

The following are new features and changes in the Java Card Development Kit Simulator, version 3.1:

  • The Java Card Development Kit Simulator now supports version 3.1 of the Java Card Platform specifications. New features include:
    • Improved API Extensibility Using Virtual Method Mapping Table
    • Support for Array Views
    • Support for large CAP file that may comprise multiple packages
    • Support for static resources in CAP files
    • Certificate API
    • Monotonic Counter API
    • System Time API
    • Extended I/O Framework

    For a complete list of supported features, see the Java Card Development Kit User Guide, Version 3.1.

  • Java Card Development Kit Tools and Java Card Development Kit Simulator are now two independent bundles, which can be downloaded separately, enabling easier update of the Development Kit Tools.
  • New samples are available to demonstrate the use of:
    • Array Views
    • Certificate Handling

The Java Card Development Kit Simulator, version 3.1 also supports new cryptographic algorithms. For a list of the supported cryptographic algorithms, see Supported Cryptography Classes section in the Java Card Development Kit User Guide, Version 3.1.
