TEEs are central to the concept of confidential computing. They create secure areas in the processor to protect data and code in use. Enclaves, a type of TEE, offer process-level isolation, ensuring that sensitive data is processed in a secure environment, invisible even to the operating system or hypervisor. TEEs provide a hardware root of trust, crucial for maintaining data confidentiality during processing, and support remote attestation, allowing external verification of the integrity and security of the environment where data is processed.
