To date, it has not been possible to perform secure IP-based IoT communications on a small low power embedded module. The reasons that this is now possible is due to the development of new secure connectivity standards combined with the development of secure low power microcontrollers with cryptographic accelerators.
This white paper details how this has been accomplished on a certified platform offering OCF’s secure IP framework and application layer, and Thread’s low-power and scalable IPv6-based network layer protocol. The processor used on the resulting module has only 96kB of RAM, but this is enough to run a REED Thread device and the OCF application stack. It has capacity spare to create additional OCF resources, e.g., add more functionality to the product. The module and the software are available and already being deployed in commercial settings.
