Hello,
I was able to find the information regarding TEE GlobalPlatform certification.
However, I was not able to find if it is required to path the certification for Trusted Applets (TA) development.
The only type of the information which I was able to find was related to the OP-TEE and it only covers questions related to the development of your own TA on some raspberry pi or similar soc.
What should anyone do, if she decides to start the development for Qualcomm implementation of the TEE?
What is the flow in that case? How should be the solution or the development team be certified?
It depends on what kind of certification that you want to pass:
1) only the TA that you developed
2) the delta Trusted OS development based on Qualcomm TEE implementation.
Anyway, for China users, please see http://www.caict.ac.cn/ywjs/hxyw/csrz/ and contact the certification lab about how to pass these kinds of Global Platform certifications.
