BYOTee: Towards Building Your Own Trusted Execution Environments Using FPGA. (arXiv:2203.04214v1 [cs.CR])

In recent years, we have witnessed unprecedented growth in using
hardware-assisted Trusted Execution Environments (TEE) or enclaves to protect
sensitive code and data on commodity devices thanks to new hardware security
features, such as Intel SGX and Arm TrustZone. Even though the proprietary TEEs
bring many benefits, they have been criticized for lack of transparency,
vulnerabilities, and various restrictions. For example, existing TEEs only
provide a static and fixed hardware Trusted Computing Base (TCB), which cannot
be customized for different …
