Trusted Execution

Definition ∞ Trusted execution refers to the ability of a computing environment to perform operations securely and privately, isolated from the host operating system and other applications. This is typically achieved through specialized hardware enclaves that protect data and code from unauthorized access, even from privileged software. It provides a verifiable guarantee of computation integrity.
Context ∞ The integration of trusted execution environments into blockchain infrastructure is a growing area of interest for enhancing security and privacy. Discussions often revolve around the security models of specific trusted execution technologies, their application in secure multi-party computation, or their role in protecting sensitive keys and data. News in this area is relevant to the development of more robust and secure decentralized systems.
