In order to support the security of IoT edge devices and cloud-to-edge connections, NXP Semiconductors has implemented AWS Greengrass hardware security integration on its Layerscape and i.MX applications processors. This feature is an extension of the built-in hardware root of trust, tamper-proof secure storage, and trusted execution environment (TEE) available on all NXP applications processor platforms.
The integration enables hardware-secured, end-to-end encryption for messages being sent between the AWS Greengrass core running on NXP applications processors and the AWS IoT cloud, or on other edge devices using the AWS IoT device SDK.
This follows NXP’s earlier introduction of a software infrastructure called EdgeScale to simplify and unify how data is collected, curated and processed at the edge. EdgeScale provides end-to-end secure provisioning and device management solutions for NXP-based systems.
The latest release of EdgeScale adds support for automatically provisioning the secure software layer and PKCS#11 crypto standard interface on top of NXP’s applications processors, enabling a seamless development and deployment experience for customers who deploy the AWS Greengrass core onto NXP-based edge devices.
