Two interesting announcements surfaced this week at the RSA Conference being held in San Francisco. The first was put out by Arm and concerns the launch of the SDK-700 System Design Kit, built on the firm’s recently released Platform Security Architecture (PSA). The SDK is targeted at developers building SoC for IoT devices, notably nodes, gateways, and embedded applications. The solution offers a computer architecture that combines processor capabilities from two families: Cortex-A (high-performance powerful processors) and Cortex-M (low-power processors, optimized for deterministic real-time embedded microcontroller applications). The hardware security base is leveraged with the TrustZone technology, and the secure development design is based on the PSA, which requires the inclusion of device identity, trusted boot sequence, secure OTA updates, and certificate-based authentication.
