Smart Home Device Security: A System View

IoT device security requires a solid understanding of embedded hardware and software capabilities, cloud-based security, and knowledge of the changing security standards implemented by local governments and global industry bodies. Today’s IoT devices must also address a growing set of requirements that include low power, cost effectiveness, and high performance.

In this presentation, we discuss what is required at a system level to secure an IoT application (smart door lock) including 1) threat models that affect smart home devices and 2) required hardware and software security features including accelerated cryptography, TRNG, hardware root-of-trust for secure boot, firmware updates, attestation, TLS, and secure processing isolation.
