Host Applications Only
A host application installs and runs Intel® DAL trusted applications on the internal platform firmware and provides the user experience to the external world. Host applications can be developed in the basic host application template created by the Intel DAL project wizard on request or in the IDE of your choice provided you adhere to the basic host application requirements of Intel DAL host applications. Intel DAL supports host application development in C++, C# and .NET*.
Host applications are debugged in the program they are developed in, e.g., Microsoft Visual Studio*, using standard code debugging procedures. When we discuss debugging in the SDK, we refer to debugging a trusted application via the host application.
OS | Versions | Development Environment |
---|---|---|
Windows* | Supported in all versions from Intel® ME 7.1, including SEC | SDK Eclipse* plugin |
Android* | Supported from Intel Atom® SoC code name Valleyview (SEC 1.0) | Eclipse + Android* Development Tools (ADT) |
Development in a Windows* environment is fully supported by the SDK. For Android development, the SDK provides additional tools which must be run independently on an Android OS. For details on these tools, see Generic Android Host Application.
Trusted application development is the same for Windows and Android platforms and can be done using the core SDK environment. Host application development differs between Windows and Android.
Management of Intel DAL Host Interface Service and DLL
Communication with Intel DAL trusted applications from a host machine requires installation of the Intel DAL Host Interface Service (jhi_service.exe) on the host. A host application interfaces to this service via a corresponding DLL (jhi.dll) that is accessible by the application. This DLL implements the jhi.h header, allowing communication with the service, which in turn communicates with Intel DAL applications.
The Intel DAL Host Interface Service and jhi.dll must match the execution environment:
- The service and DLL change with the DAL version.
- The service and DLL are different for emulated execution and execution opposite real firmware.
Android: In place of the jhi.dll there is com.intel.security.dalinterface.jar which provides the JHI APIs for Android host applications.
