Secure Object Sharing on Java Card

This research concerns enhancement in on-card verification of downloaded applets in Java Card technology. In this thesis, we propose the on-card installer with a one-way hash function to support on-card verification of download applets. The hash value generated from the on0card installer is used to verify download applets hwyn they try to gain a SIO from a server applet. This thesis is organized into five chapters and an appendix. Chapter 1, Introduction, depicts the background of Java Card technology, the current problem in the Java Card platform, and the objectives of this research. Chapter 2, Literature Review, introduces fundamental concepts and background knowledge on Smart Card, Java Card, and message digest algorithms. Chapter 3, Secure Object Sharing, presents solution to meet the objectives. Chapter 4, Secure Object Sharing Simulation, simulates the object sharing process between a server applet and a client applet. Chapter 5, Conclusion, draws a conclusion ofenhancement in on-card verification of downloaded applets. Appendix presents source codes that are used for the simulation
