Research Of The Secure Computing Based On Java USIM Card

Mobile telecommunications continue to be phenomenally successful with an estimated one billion mobile subscribers. There are more mobile phones than internet connected PCs. It is an easy and convenient way to communicate with others and being accessible 7 days a week, 24 hours a day, no matter where you are. In addition to voice service, various value-adding services, such as mobile payment, stock service, are widely used for its convenience and practicability.Java USIM Card provides a secure computing environment for multiple applications that run on mobile phone with very limited memory and processing capabilities. Multiple value-adding applications can be deployed on a single card, and new applications can be added even after it has been issued to end users. Value-adding applications written in the Java programming language can be executed securely on cards from different vendors. The dissertation focuses on Java USIM secure computing environment, provides the implement of the Java Card Virtual Machine, designs generations Java Card garbage collector algorithm, proposes USIM card security personalization protocol based on NTRU Cryptography algorithm, extends Java Card RMI (Remote Method Invoke) function, and researches Rights Management for Digital Content in Mobile Network based on Java USIM. The main contributions in this thesis are as fellow:1. Cross-layer Design for Generations Java Card Garbage Collection algorithmThe Java Card objects management, transactions and flush physical traits are analyzed. We propose and implement the adaptive generations' mark-sweep-copy algorithm for Java Card Garbage Collection by...
