Abstract

The present invention describes a facility which may be used in conjunction with SmartCard technology. Application Protocol Data Units (APDUs) are used to communicate with SmartCards. The management of these units is the primary focus and advantage of this facility. Smartcard environments can require that the APDUs conform to an environment specific format, and they can have different methods of sending information to and from a SmartCard. Other tools exist which assist in creation of ADPUs for SmartCard communication, but they are most likely tied to a single SmartCard environment. Application Protocol Data Unit—Management Facility (AMF) has numerous advantages over other APDU generation tools and are described.

Claims

1. A computer based system employing an Application Protocol Data Unit—

Management Facility (AMF), to communicate with SmartCards, comprising;

means for managing Application Protocol Data Units (APDUs);

means for employing said Application Protocol Data Unit—

Management Facility as a 100% pure Java tool;

means for employing said Application Protocol Data Unit—

Management Facility (AMF) to create sequences of said Application Protocol Data Units (APDUs) via a high level user interface; and

said sequences are saved in an intermediate form that is not tied to any specific SmartCard environment,

allowing any said SmartCard environment to use APDU—

Management Facility (AMF) output.

2. The System of claim 1 wherein said APDU—

Management Facility (AMF) system can employ various types of plug-ins to accomplish any or all of the following;

export said APDU sequences to a specific SmartCard environment, import sequences from a specific Smart Card environment into said AMF'"'"'s intermediate format, analyze the execution results from a specific said SmartCard environment, initiate communication with a specific said SmartCard environment and execute APDU sequences, showing the analysis results.

3. The System of claim 1 wherein said SmartCard is JavaCard.

4. The system of claim 1 wherein said Application Protocol Data Unit—

Management Facility (AMF) increases productivity when developing data packages to communicate with SmartCards.

5. The system of claim 1 wherein any Application Protocol Data Unit—

Management Facility (AMF) includes an export facility whereby the user may export an APDU sequence as a JavaCard 2.0 simulator Script file.

6. The system of claim 1 wherein said AMF is not tied to any SmartCard environment that can be plugged into any SmartCard environment, such as Point of Sale Card terminal and an actual Smartcard implementation, or a PC-based simulator.

7. A computer based method employing an Application Protocol Data Unit—

Management Facility (AMF), to communicate with SmartCards, comprising the steps of;

managing Application Protocol Data Units (APDUs);

employing said Application Protocol Data Unit—

Management Facility as a 100% pure Java tool;

employing said Application Protocol Data Unit—

Management Facility (AMF), to create sequences of said Application Protocol Data Units (APDUs) via a high level user interface; and

said sequences are saved in an intermediate form that is not tied to any specific SmartCard environment, allowing any said SmartCard environment to use APDU—

Management Facility (AMF) output.

8. The method of claim 7 wherein said APDU—

Management Facility (AMF) system can employ various types of plugins to accomplish any or all of the following;

export said APDU sequences to a specific SmartCard environment, import sequences from a specific SmartCard environment into said AMF'"'"'s intermediate format, analyze the execution results from a specific said SmartCard environment, initiate communication with a specific said SmartCard environment and execute APDU sequences, showing the analysis results.

9. The method of claim 7, wherein said SmartCard is JavaCard.

10. The method of claim 7 wherein said Application Protocol Data Unit—

Management Facility (AMF) increases productivity when developing data packages to communicate with SmartCards.

11. The method of claim 7 wherein any Application Protocol Data Unit—

Management Facility (AMF) includes an export facility whereby the user may export an APDU sequence as a JavaCard 2.0 simulator Script file.

12. The method of claim 7 wherein said AMF is not tied to any SmartCard environment that can be plugged into any SmartCard environment, such as Point of Sale Card Terminal and an actual Smartcard implementation, or a PC-based simulator.

13. A computer readable program having data structures included on a computer readable medium which causes the display on a data processor controlled display of a Application Protocol Data Unit—

Management Facility (AMF), to communicate with SmartCards, comprising;

means for managing Application Protocol Data Units (APDUs);

means for employing said Application Protocol Data Unit—

Management Facility as a 100% pure Java tool;

means for employing said Application Protocol Data Unit—

Management Facility (AMF), to create sequences of said Application Protocol Data Units (APDUs) via a high level user interface; and

said sequences are saved in an intermediate form that is not tied to any specific SmartCard environment, allowing any said SmartCard environment to use APDU—

Management Facility (AMF) output.

14. A computer readable program of claim 13 wherein said APDU—

Management Facility (AMF) system can employ various types of plug-ins to accomplish any or all of the following;

export said APDU sequences to a specific SmartCard environment, import sequences from a specific SmartCard environment into said AMF'"'"'s intermediate format, analyze the execution results from a specific said SmartCard environment, initiate communication with a specific said SmartCard environment and execute APDU sequences, showing the analysis results.

15. A computer readable program of claim 13 wherein said SmartCard is JavaCard.
