MicroPython-based Sensor Node with Asymmetric Encryption for Ubiquitous Sensor Networks

This work introduces a new microcomputing node with long-term resistant data security, based on asymmetric and symmetric encryption combined with the modern and established scripting language Python. The presented microcomputing node integrates a MicroPython runtime environment to address a wide audience of application engineers as user base instead of a selected group of embedded engineers, who have deep knowledge in programming IoT devices using C/C++. It combines its scripting capabilities with security features of modern smartcards and secure cellular networking based on 4G.
