Abstract

The present invention provides an apparatus enabling the Human Interface Device (HID) to provide a smart card interface and an operating method therein. The apparatus is a virtual reader driver layer comprising a monitoring module for monitoring the connection and disconnection of the HID and obtaining the name of the HID object; a PC/SC interface module for providing a driver interface complying with the PC/SC Specification to the application layer, receiving the IRP sent from the application layer, and transmitting it to a data processing module; and a data processing module for receiving and processing the IRP sent from the application layer through the PC/SC interface module, and sending the IRP to the HID device class driver layer in accordance with the name of the HID object obtained by the monitoring module.

Claims

1. A method for operating an apparatus for enabling a human interface device (HID) to provide a smart card interface, the apparatus being a virtual reader driver layer comprising

a monitoring module for monitoring connection and disconnection of the HID and obtaining a name of a human interface device object,

a Personal Computer/Smartcard (PC/SC) interface module for providing a driver interface complying with a PC/SC Specification Version 2.01.3 to an application layer, receiving an I/O Request Package (IRP) sent from the application layer, and transmitting it to a data processing module, and

the data processing module for receiving and process the IRP sent from the application layer through the PC/SC interface module, and sending the IRP to a HID device class driver layer in accordance with the name of the human interface device object obtained by the monitoring module,

the method comprising:

the monitoring module monitoring if the HID is connected;

if the HID is connected, the monitoring module obtaining the name of the human interface device object at lower-level;

the monitoring module determining if the connected HID needs to be processed;

the monitoring module initializing variables in a program and notifying a smart card service system of the connection of a smart card;

the monitoring module monitoring if the HID is disconnected;

if so, the monitoring module releasing system resources occupied by the HID since its connection, and notifying the smart card service system of the disconnection of the smart card;

the data processing module receiving the IRP relating to the HID, which is sent from the application layer, and reorganizing the IRP in accordance with a HID data transfer protocol; and

the data processing module sending the reorganized IRP to the HID device class driver layer at lower-level for data interacting, and returning the result to the application layer.

2. The method of claim 1, wherein the monitoring module monitors the connection of the HID with a registered callback function.

3. The method of claim 1, wherein the monitoring module monitors the connection of the HID in the a polling manner.

4. The method of claim 1, wherein the monitoring module obtains the name of the human interface device object at lower-level in accordance with arguments of a registered callback function.

5. The method of claim 1, wherein the monitoring module monitors the disconnection of the HID with a registered callback function.

6. The method of claim 1, wherein the monitoring module monitors the disconnection of the HID in a polling manner.

7. The method of claim 1, wherein the data processing module performs data interaction with the HID device class driver layer at lower-level by constructing the IRP of IOCTL_HID_* type and in accordance with the name of the human interface device object.

8. The method of claim 1, further comprising obtaining the name of the human interface device object for establishing a relationship of the data processing module with the HID device class driver layer.
