ARM builds up security in the tiniest IoT chips

Small, low-power chip designs now incorporate ARM's TrustZone technology

The platform can get a device set up and connected and then handle firmware updates over time. It also has a role to play in keeping IoT chips secure.

When a device boots up for the first time in the field, mbed Cloud can provide a security key for the communications channel and specify who can get access to the data from the device, based on enterprise policies.

The service can also help to prevent IoT-based denial-of-service attacks by monitoring what’s going on in the network. If there are abnormally chatty devices, it can isolate them or shut them down.

The SaaS platform isn’t just for devices with ARM-based chips or the mbed OS. If customers have legacy devices with other chips running Linux or freeRTOS, for example, ARM has a software module for connecting them to the mbed Cloud.

The service can be run on multiple public clouds, including Amazon’s and IBM’s.
