As it said on website: Reap SDK can support project modules or settings developed based on the existing Micro Controller Unit (MCU). Reap SDK allows you to reuse existing native SDK code to have interoperability between codes and minimize maintenance and management costs. In addition, a unique ID (private key) is created for each IoT device and stored in the internal non-volatile memory.

It seems that such solutions will help to greatly increase the speed of the system while maintaining security at a very high level.
