Tizen Native API 6.0
The TEF provides the TEE Client API as defined by the GlobalPlatform TEE standard for connecting to applications executed in TrustZone.
This way we have, so called, two worlds: rich world (like linux) with Client Application (CA) and secure world with Trusted Application (TA).
This API is not for use by third-party applications. Your application requires a partner level privilege, http://tizen.org/privilege/tee.client.
For security reasons, each device vendor usually uses their own TEE solution. If you intend your LibTeec application to be used on a real device, you must test your application on the TEE solution provided by the specific vendor. When developing and installing your trusted application, refer to the documentation provided by the vendor.
It is recommended to use features in your application for reliability. You can check if the device supports the related features for this API by using System Information, and control your application's actions accordingly. To ensure your application is only running on devices with specific features, please define the features in your manifest file using the manifest editor in the SDK. More details on using features in your application can be found in Feature Element.
