%X A formal method was used to analyze the application isolation and objects sharing mechanism in Java smart card. A trust model was used to clarify the relationship of the inter-applet shareable objects. According to the constraint of trust transfer, it was inferred that, in addition to the applet level access controls, a global security policy of card was necessary to prevent the unauthorized information flow. Finally a simple implementation of the global security mechanism was designed.
