Toolkit event configuration of applets on a card computing device with installation parameters

1. A method for registering events, comprising:

receiving, by a runtime environment executing on a card computing device, a first install command for an applet, the first install command comprising a tag-length-value (TLV) structure with a first tag identifying a first event-list for registration with a toolkit registry of the runtime environment,

wherein the first event-list comprises a first toolkit event;

executing, by the runtime environment, the first install command for the applet;

creating, in response to executing the first install command, an applet instance of the applet;

registering the applet instance with the toolkit registry by:

generating, by the runtime environment, a toolkit registry object for the applet instance; and

assigning the toolkit registry object to the applet instance;

identifying, based on the first tag of the TLV structure of the first install command, the first toolkit event of the first event-list; and

registering the first toolkit event of the first event-list to the toolkit registry object assigned to the applet instance.

2. The method of claim 1 , further comprising:

receiving, after registering the first event-list with the toolkit registry, a store data command for the applet, the store data command comprising a TLV structure with a second tag identifying a second event-list, and

wherein the second event-list comprises a second toolkit event;

executing, by the runtime environment, the store data command for the applet;

identifying, based on the second tag of the TLV structure of the store data command, the second toolkit event; and

registering the second toolkit event of the second event-list to the toolkit registry object, resulting in registration of the first toolkit event of the first event-list and the second toolkit event of the second event-list to the toolkit registry object.

3. The method of claim 2 , further comprising:

receiving a second install command for the applet, the second install command comprising a TLV structure with a third tag identifying a third event-list, and

wherein the third event-list comprises a third toolkit event;

executing, by the runtime environment, the second install command for the applet;

identifying, based on the third tag of the TLV structure of the second install command, the third toolkit event of the third event-list; and

registering the third toolkit event of the third event-list to the toolkit registry object by overwriting, with the third event-list, registration of the first event-list and the second event-list to the toolkit registry object.

4. The method of claim 1 , further comprising:

executing a determination, in response to executing the first install command, that the first toolkit event is registered to a different toolkit registry object assigned to a different applet instance within the toolkit registry; and

terminating, in response to the determination, the first install command.

5. The method of claim 1 , further comprising:

sending, to a mobile terminal operatively connected to the card computing device, a proactive command comprising the first event-list for the applet;

receiving, from the mobile terminal and after sending the first event-list, a command triggering the first toolkit event; and

activating, in response to triggering of the first toolkit event, the applet using the runtime environment.

6. The method of claim 1 , wherein the card computing device is a universal subscriber identity module (USIM) card.

7. The method of claim 1 , further comprising:

sending, to a mobile terminal operatively connected to the card computing device, a proactive command comprising the first event-list for the applet;

receiving, from the mobile terminal and after sending the first event-list, a command triggering the first toolkit event; and

activating, in response to triggering of the first toolkit event, the applet using the runtime environment.

8. The method of claim 7 , wherein the mobile terminal is one selected from a group consisting of mobile phone, machine-to-machine (M2M) device, and Internet-of-Things (IoT) device.

9. The method of claim 1 , wherein the applet comprises a set of Java classes and the card computing device conforms to a JavaCard Platform.

10. A system for registering events, comprising:

a card computing device comprising a runtime environment executing on a processor, the runtime environment being configured to:

receive, by a runtime environment executing on a card computing device, a first install command for an applet, the first install command comprising a tag-length-value (TLV) structure with a first tag identifying a first event-list for registration with a toolkit registry of the runtime environment,

wherein the first event-list comprises a first toolkit event;

execute, by the runtime environment, the first install command for the applet;

create, in response to executing the first install command, an applet instance of the applet; and

register the applet instance with the toolkit registry by:

generating, by the runtime environment, a toolkit registry object for the applet instance; and

assigning the toolkit registry object to the applet instance;

identifying, based on the first tag of the TLV structure of the first install command, the first toolkit event of the first event-list; and

registering the first toolkit event of the first event-list to the toolkit registry object assigned to the applet instance.

11. The system of claim 10 , wherein the runtime environment is further configured to:

receive, after registering the first event-list with the toolkit registry, a store data command for the applet, the store data command comprising a TLV structure with a second tag identifying a second event-list, and

wherein the second event-list comprises a second toolkit event;

execute, by the runtime environment, the store data command for the applet;

identify, based on the second tag of the TLV structure of the store data command, the second toolkit event; and

register the second toolkit event of the second event-list to the toolkit registry object, resulting in registration of the first toolkit event of the first event-list and the second toolkit event of the second event-list to the toolkit registry object.

12. The system of claim 11 , wherein the runtime environment is further configured to:

receive a second install command for the applet, the second install command comprising a TLV structure with a third tag identifying a third event-list, and

wherein the third event-list comprises a third toolkit event;

execute, by the runtime environment, the second install command for the applet;

identify, based on the third tag of the TLV structure of the second install command, the third toolkit event of the third event-list; and

register the third toolkit event of the third event-list to the toolkit registry object by overwriting, with the third event-list, registration of the first event-list and the second event-list to the toolkit registry object.

13. The system of claim 10 , wherein the runtime environment is further configured to:

execute a determination, in response to executing the first install command, that the first toolkit event is registered to a different toolkit registry object assigned to a different applet instance within the toolkit registry; and

terminate, in response to the determination, the first install command.

14. The system of claim 12 , wherein the runtime environment is configured to receive the first event registration for the applet from a remote server.

15. The system of claim 10 , wherein the card computing device is a universal subscriber identity module (USIM) card.

16. The system of claim 10 , wherein the runtime environment is further configured to:

send, to a mobile terminal operatively connected to the card computing device, a proactive command comprising the first event-list for the applet;

receive, from the mobile terminal and after sending the first event-list, a command triggering the first toolkit event; and

activate, in response to triggering of the first toolkit event, the applet using the runtime environment.

17. The system of claim 16 , wherein the mobile terminal is one selected from a group consisting of mobile phone, machine-to-machine (M2M) device, and Internet-of-Things (IoT) device.

18. The system of claim 1 , wherein the applet comprises a set of Java classes and the card computing device conforms to a JavaCard™ Platform.
