JavaCard Project

Marwan Nour | [email protected]

JavaCard Project for the Embedded Systems Security course at École Polytechnique.

Note: Using vagrant with the provided Vagrantfile is recommended. You will have to modify the build.xml file to point to the ext/ directory.

Usage

  1. Go to the project directory (same directory as an build.xml file) and run ant to compile the .java files into .cap files.
  2. Install the .cap file into your card with gp --install <applet.cap> --params <pin_in_hex>
  3. Run the Python client in Client/ directory

Files:

  • JavaCardProject.java
  • clientJavaCardProject.py
