QCOM-TEE Library provides an interface for communication to the Qualcomm® Trusted Execution Environment (QTEE) via the QCOM-TEE driver registered with the Linux TEE subsystem.
QCOM-TEE Library supports Object-based IPC with QTEE for user-space clients via the TEE_IOC_OBJECT_INVOKE IOCTL from the Linux TEE subsystem .
QTEE enables Trusted Applications (TAs) and Services to run securely. It uses an object-based interface, where each service is an object with sets of operations. Clients can invoke these operations on objects, which can generate results, including other objects. For example, an object can load a TA and return another object that represents the loaded TA, allowing access to its services.
Kernel and userspace services are also available to QTEE through a similar approach. QTEE makes callback requests that are converted into object invocations. These objects can represent services hosted within the kernel or userspace process.
On an x86-64 Ubuntu machine, assuming you have a cross-build toolchain along with all the build-time dependencies available, such as CMake, you can build the project and run the unittest with
git clone https://github.com/quic/quic-teec.git
cd quic-teec
mkdir build
cmake .. -DCMAKE_TOOLCHAIN_FILE=CMakeToolchain.txt -DBUILD_UNITTEST=ON
Edit CMakeToolchain.txt for the toolchain of your choice.
In order to build the qcomtee library, you require QCBOR. It is not available using the standard Ubuntu repository. If you do not have it installed on your machine, you can obtain it from here.
Use -DQCBOR_DIR_HINT=/path/to/installed/dir to specify the QCBOR dependency.
