Abstract
Various configurations and methods for providing a secure transfer of data from computing device sensors to a Trusted Execution Environment (TEE) are disclosed. As disclosed, various data flows, data sequences, and configurations are provided to allow sensor data to maintain integrity and confidentiality while being accessed by trusted agents of a TEE. In an example, a microcontroller-based TEE is operated to communicate with a sensor hub via a secure hardware channel. The microcontroller-based TEE is configured to receive the sensor data via the secure hardware channel, and communicate the sensor data to other trusted agents in the computing system via secure communications. Other variations of secure communications among multiple sensors, trusted agents, TEEs, and third party services are also disclosed.
