Dear,
We have made a GlobalPlatform Internal API on Keystone using Keystone SDK.
GlobalPlatform Internal API is the most common API on Smartphone TEE and widely used.
The API is built as a portable library that separates CPU architecture dependant/independent. It can be portable and runs on Intel SGX.
We measured the performance of each API in an enclave.
The detail is presented at RISC-V GlobalForum on 3/September.
Title: Portable Implementation of GlobalPlatform API for TEE
Presentator: Kenta Nakajima & Kuniyasu Suzaki, Technology Research Association of Secure IoT Edge Application Based on RISC-V Open Architecture (TRASIO)
Please attend the slot. Thank you.
