What is the role of hardware support, such as ARM TrustZone, in implementing secure enclaves?
ARM TrustZone is a hardware support feature that plays a crucial role in implementing secure enclaves, which are isolated and protected execution environments within a computer system. Secure enclaves provide a secure space for executing sensitive code and protecting critical data from unauthorized access or tampering. In this context, ARM TrustZone serves as a foundation
What is the purpose of the monitor in a secure enclave system?
The purpose of the monitor in a secure enclave system is to provide a trusted execution environment for sensitive computations and to protect the confidentiality, integrity, and availability of the data and code within the enclave. A secure enclave is a hardware-based security mechanism that isolates a portion of a computer system's memory and execution
How do enclaves address the problem of untrustworthy operating systems?
Enclaves are a powerful mechanism in addressing the problem of untrustworthy operating systems in the field of computer systems security. Enclaves provide a secure and isolated environment within a larger system, allowing critical and sensitive computations to be performed with a high degree of trust, even in the presence of potentially compromised or untrustworthy components.
