Secure architectures for the IoT
summary
arm proposes a concrete baseline: a platform security architecture with threat analyses for smart meters, IP cameras and asset trackers, hardware requirements (TRNG, secure storage, crypto acceleration), and open-source firmware called trusted firmware-M implementing a secure partition manager on Cortex‑M devices. Claims include certificate-based identities, secure boot, and OTA updates; a new on‑chip enclave called cryptoIsland for key protection; cites 100 billion ARM cores shipped and another 100 billion expected in four years.
