Trusted Execution Environment (TEE)
A hardware-isolated secure region provided by CPU vendors such as Intel SGX and AMD SEV, allowing code and data to execute in a protected environment. It prevents external software, including operating systems and hypervisors, from accessing its internal contents.
Core Facts
Timeline (last 90 days)
Security assurance at the hardware level is typically implemented through Trusted Execution Environment (TEE) technology, which carves out hardware-protected isolated regions within the processor.
Confidential computing relies on Trusted Execution Environments (TEEs) provided by CPU vendors; data is decrypted and processed within hardware-isolated enclaves, and cloud service operators, the virtual machine management layer, and even the operating system kernel cannot access plaintext data inside the enclave.
Trusted Execution Environments (TEE) and end-to-end encryption typically introduce additional computational overhead and latency, requiring a trade-off between performance and security.
