Introducing IO Devices into Trusted Execution Environments
Offered By: Linux Foundation via YouTube
Course Description
Overview
Explore the challenges and solutions for integrating IO devices into Trusted Execution Environments (TEEs) in this informative conference talk by Jun Nakajima from Intel Corporation. Delve into the world of confidential computing and learn how it protects data in use through hardware-based TEEs like Intel SGX and the upcoming Trust Domain Extensions (Intel TDX). Understand the current limitations of PCIe-attached devices outside the TEE's trust boundary and their impact on data transfer and processing. Discover the security implications and performance drawbacks of the current method involving shared memory buffers and software-based encryption/decryption. Gain insights into the necessary security and software changes required to support IO in trusted execution environments, including the software requirements for TEE VMs to securely use devices in the Trusted Computing Base with DMA operations against confidential memory using encryption/decryption.
