Hardware Security and Secure Enclave Questions

This topic covers trusted execution environments and hardware backed security primitives such as the Secure Enclave. Candidates should understand isolated execution and storage for keys, hardware backed attestation and provisioning flows, secure boot and firmware concerns, the constrained APIs and performance characteristics of secure coprocessors, and trade offs between implementing features in hardware versus software. Practical discussion should include how to integrate hardware backed keys into system architecture, handle attestation and provisioning, mitigate side channel risks, and manage firmware and supply chain threats.
