Confidential Computing: Trusted Execution Environments (TEE)

Confidential computing, data'yı use (işlem) sırasında şifreli tutan ve Trusted Execution Environments (TEE) ile memory encryption sağlayan güvenlik yaklaşımıdır; data at rest ve data in transit'e ek olarak data in use protection sunar. TEE hardware teknolojileri: Intel SGX (Software Guard Extensions) application-level enclave'lar ile sensitive code ve data isolation sağlar, AMD SEV (Secure Encrypted Virtualization) VM-level memory encryption yapar ve ARM TrustZone processor-level secure world oluşturur. Confidential computing use cases: multi-party computation (birden fazla party'nin data'sını shared computation için kullanma without data sharing), secure machine learning (encrypted data üzerinde model training/inference), regulated data processing (GDPR, HIPAA compliance için data processing during encryption) ve secure enclaves (blockchain, DRM, key management). Cloud provider offerings: AWS Nitro Enclaves, Azure Confidential Computing (SGX, SEV-SNP VMs) ve Google Cloud Confidential VMs ile managed confidential computing services sunulur. Confidential computing challenges: performance overhead (encryption/decryption latency), attestation complexity (enclave identity verification), limited programming model ve debugging difficulty.
