Abstract
A capability enabling method and apparatus. A secure element (SE) establishes, with a trusted execution environment (TEE), a session for communication. The SE sends, to the TEE, an obtaining instruction to obtain a security certificate of the TEE. After receiving the obtaining instruction, the TEE generates the security certificate based on attribute information of the TEE, and sends the generated security certificate to the SE. After the SE receives the security certificate, the SE determines, based on the security certificate and a preset security policy, that the TEE is in a secure state. After the SE determines that the TEE is in the secure state, the SE enables a first capability for a third-party service in the SE based on a second capability of the TEE.
