You are designing a high-security IoT device and must ensure its private keys are never exposed in system memory or storage. Which hardware component should you integrate, and how does the Azure IoT SDK support it?

โœ“ Correct Answer & ExplanationIoT Security

Correct Answer

Integrate a Hardware Security Module (HSM) or TPM, and use HSM-based security providers in the Azure IoT Device SDK

Why This Answer Is Correct

HSMs and TPMs provide secure storage for cryptographic keys and perform operations within their hardware boundary. The Azure IoT Device SDK has built-in security provider libraries that interface with HSM/TPM chips, keeping the private key secure and unexposed.
