A Trusted Execution Environment (TEE) is a secure area within a main processor that guarantees code and data loaded inside are protected with respect to confidentiality and integrity. It provides a hardware-isolated space where sensitive computations can be performed, shielded from other software on the system, including the operating system. This technology establishes a verifiable foundation of trust for applications. TEEs are critical for securing digital assets and private data processing.
Context
Trusted Execution Environments are gaining prominence as a solution for enhancing security and privacy in cloud computing and blockchain applications. A key discussion involves their adoption in Web3 for off-chain computation, protecting private keys, or enabling privacy-preserving smart contracts. News about confidential computing advancements or hardware-backed security solutions often highlights the increasing relevance of TEEs.
