Reads a command received through the memory unit and the input / output interface, selects an application issuer applet corresponding to the command, generates (or confirms) response data corresponding to the selected application issuer applet, and selects the input / output interface; A GP (Global Platform) based integrated circuit (IC) card comprising a processor for outputting through the memory module, wherein the memory unit may include two or more applet functions selected by a function selection flag included in a command received through the input / output interface. PSD Stars Apple And an application issuer applet and data corresponding to each applet function, wherein the processor reads a command selected through the input / output interface to select an application issuer applet for each specific PSD, and includes a function selection flag. The present invention relates to a global platform-based IC card for activating an applet function selected by the function selection flag among two or more applet functions included in the application issuer applet for each selected specific PSD when checking the function selection flag.

The Global Platform (www.globalplatform.org) was created in late 1999 as part of an effort by more than 50 smart card affiliates to form a council to unify industry standards related to smart cards. The GP proposes all smart card related industry standards including smart card itself, smart card management system (SCMS) and card terminals, and GP standards are very important especially in open smart card environment. Taking place.

Currently, the GP standard for smart card is Global Platform Card Specification v2.1.1, released in March 2003. Recently, Java card, which accepts GP 2.1.1 version, has been introduced, especially in domestic banks and mobile operators. In addition to Visa, MasterCard has also become a full member of the GP Council.

In more detail, FIG. X illustrates a structure of a Java GP card having a GP compliant with the GP 2.2.1 standard. However, it should be noted that the GP card is not limited to Java cards.

Referring to FIG. 1, a Java GP card is provided with a card manager, an OPEN, and a security domain (SD) in a conventional Java card.

The card manager includes a security domain and an OPEN, and performs a function of managing a Java card applet and a card life cycle.

Issuer Security Domain (ISD) in the card manager component is a ROM applet provided by an issuer that issues a card, and the card issuer (Issuer) manages a key for issuance through the ISD. The key can be used to install or delete applets.

In addition, the PSD (Application Provider Security Domain or Provider Security Domain) in the component of the card manager is an applet that manages the key of the application provider for developing and providing an applet, the application provider for applet issuance through the PSD It manages keys and can install or delete applets through them.

In addition, the OPEN of the card manager manages various kinds of information existing in the Java GP card, or selects and runs an applet. Therefore, the applet provided in the Java GP card accesses OPEN through a GP API (Application Programming Interface), and the OPEN manages the corresponding information while providing a storage area for managing characteristics or information about the applet. That is, all applets (eg, card issuer applets and application provider applets) present in the Java GP card operate only within the operating range determined by the card manager.

However, the GP currently allows only one applet per application provider, and includes a problem of restricting service diversification by restricting provision of multiple applications for each application provider through a GP card.

Among the two or more applet functions included in the selected application issuer applet for each specific PSD, response data corresponding to the applet function selected and activated by the function selection flag is generated (or confirmed) and output through the input / output interface. Global platform based IC card.

I / O interface for inputting and outputting data,

A processor that reads a command received through the input / output interface, selects an application issuer applet corresponding to the command, generates (or confirms) response data corresponding to the selected application issuer applet, and outputs the output through the input / output interface; In the GP (Global Platform) based integrated circuit (IC) card operating method,

If an application issuer applet corresponding to a command received through the input / output interface is selected, reading the command to check whether a function selection flag is included;

Activating an applet function corresponding to the function selection flag among two or more applet functions included in the selected application issuer applet when the function selection flag is checked; And

Among the two or more applet functions included in the selected application issuer applet for each specific PSD, a response data corresponding to the applet function selected and activated by the function selection flag is generated (or confirmed) and processed to be output through the input / output interface. Global platform-based IC card operating method, characterized in that comprises a.

The method of claim 3, wherein

And if the function selection flag is not confirmed, generating (or checking) response data corresponding to the selected application issuer applet and outputting the response data through the input / output interface. .

A computer-readable recording medium which records a program for executing the method of claim 3 or 4.
