Abstract

In a distributed computing system which employs smart cards to provide services, the need for a fixed mapping between methods that can be invoked from a card application and APDU messages is avoided. A card skeleton provides a decoding table to a client proxy when a connection is established between a card and a terminal. With the information provided from the skeleton, the proxy dynamically maps methods to APDU messages, for communication during a given session. As a result, if the on-card application is enhanced to provide new methods, its corresponding skeleton is upgraded to recognize those methods. When the card is connected to a terminal, the updated information is provided to the proxy at the terminal, to enable the user to access the enhanced features of the application.
