Nikolov, Neven, Nakov, Ognyan.  2019.  Research of Secure Communication of Esp32 IoT Embedded System to.NET Core Cloud Structure Using MQTTS SSL/TLS. 2019 IEEE XXVIII International Scientific Conference Electronics (ET). :1–4.

This paper studies and describes encrypted communication between IoT cloud and IoT embedded systems. It uses encrypted MQTTS protocol with SSL/TLS certificate. A JSON type data format is used between the cloud structure and the IoT device. The embedded system used in this experiment is Esp32 Wrover. The IoT embedded system measures temperature and humidity from a sensor DHT22. The architecture and software implementation of the experimental stage are also presented.
