Confidential Computing

Confidential Computing

Confidential computing protects data during processing, completing the encryption lifecycle alongside protection at rest and in transit. Trusted Execution Environments (TEEs) like Intel SGX, AMD SEV, and ARM TrustZone provide hardware-isolated processing environments. These technologies enable secure processing in untrusted environments, including public clouds and edge devices.

Applications of confidential computing extend beyond basic encryption. Secure databases process encrypted queries without exposing data. Privacy-preserving analytics run in secure enclaves. Multi-party computation leverages TEEs for efficient secure computation. However, side-channel attacks and limited enclave sizes require careful implementation and ongoing research.
