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 information related to an event for an arbitrary security domain when the event for the arbitrary security domain is generated;
- and
- transmitting the information related to the event to at least one other security domain,
- wherein the information related to the event is sent via a TEE kernel.
A security domain management apparatus for managing at least one security domain in a trusted execution environment including the at least one security domain, comprising:
- a storage unit configured to store the at least one security domain;
- and
- a controller configured to obtain information related to an event for an arbitrary security domain, and transmit the information related to the event to at least one other security domain, when the event for the arbitrary security domain is generated,
- wherein the controller is further configured to transmit the information related to the event via a TEE kernel.
