Method and apparatus for security domain management in trusted execution environment

1. A security domain management method for managing at least one security domain in a trusted execution environment (TEE) including the at least one security domain, comprising:

obtaining property information related to a security domain;

registering the security domain in a notification service to receive information related to an event, if the property information is not NULL;

obtaining the information related to the event for a security domain if the event for the security domain is identified; and

notifying at least one other security domain of the information related to the event for the security domain based on information for the notification service, the information for the notification service being determined based on a result of the registration,

wherein the information related to the event is sent via a TEE kernel, and

wherein the information for the notification service includes at least one identifier of the at least one other security domain, at least one group identifier of the at least one other security domain, an identifier of the security domain, and valid period information.

2. The method of claim 1 , wherein the information comprises at least one of information related to scheduling, maintenance, ownership change, domain migration, or a state change of a security application or other security domain related to the security domain.

3. The method of claim 1 , further comprising:

receiving an event buffer allocation request for the security domain; and

generating an event buffer for the security domain and allocating the event buffer to the security domain,

wherein the information related to the event is updated in the event buffer allocated to the security domain if the event is identified.

4. The method of claim 3 , further comprising:

generating a list of security domains associated with the security domain,

wherein transmitting the information related to the event comprises transmitting the information related to the event to at least one of the security domains included in the list.

5. The method of claim 4 , further comprising:

receiving a renewal request for the list; and

registering identification information for a security domain to be added to the list in response to the renewal request.

6. The method of claim 3 , further comprising:

receiving a release request of the event buffer allocated to the security domain from the security domain; and

releasing the event buffer.

7. The method of claim 3 , further comprising:

transmitting a push notification to the at least one other security domain, if the information related to the event is updated.

8. The method of claim 1 , further comprising:

receiving a request for an event buffer list allocated to security domains associated with the security domain from the security domain; and

transmitting the event buffer list to the security domain,

wherein the information related to the event of the security domain is transmitted to a security domain included in the event buffer list.

9. The method of claim 1 , wherein the information for the notification service includes at least one of an event identifier, event scheduling information, or other information.

10. An apparatus for managing a security domain in a trusted execution environment including the security domain, comprising:

a storage unit configured to store at least one security domain; and

a controller configured to:

obtain property information related to the security domain,

register the security domain in a notification service to receive information related to an event, if the property information is not configured to NULL,

obtain the information related to the event for a security domain if the event for the security domain is identified, and

notify the information related to the event for the security domain to at least one other security domain based on information for the notification service, the information for the notification service being determined based on a result of the registration,

wherein the information related to the event is sent via a trusted execution environment (TEE) kernel, and

wherein the information for the notification service includes at least one identifier of the at least one other security domain, at least one group identifier of the at least one other security domain, an identifier of the security domain, and valid period information.

11. The apparatus of claim 10 , wherein the information comprises at least one of information related to scheduling, maintenance, ownership change, domain migration, or a state change of a security application or other security domain related to the security domain.

12. The apparatus of claim 10 , wherein the controller is configured to generate an event buffer for the security domain and allocate the event buffer to the security domain, if receiving an event buffer allocation request for the security domain, and

wherein the information related to the event is updated in the event buffer allocated to the security domain if the event is identified.

13. The apparatus of claim 12 , wherein the controller is further configured to generate a list of security domains associated with the security domain, and transmit the information related to the event to at least one of the security domains included in the list.

14. The apparatus of claim 13 , wherein the controller is configured to register identification information for a security domain to be added to the list in response to a renewal request, if receiving the renewal request for the list.

15. The apparatus of claim 12 , wherein the controller is configured to release an allocation of the event buffer, if receiving a release request of the event buffer allocated to the security domain from the security domain.

16. The apparatus of claim 12 , wherein the controller is configured to transmit a push notification to the at least one other security domain, if the information related to the event is updated.

17. The apparatus of claim 10 , wherein the controller is configured to transmit the event buffer list to the security domain, if receiving a request for an event buffer list allocated to security domains associated with the security domain from the security domain, and

wherein the information related to the event of the security domain is transmitted to a security domain included in the event buffer list.

18. The apparatus of claim 10 , wherein the information related for the notification service comprises at least one of an event identifier, event scheduling information, or other information.
