Several communication protocol technologies were studied and applied to interconnect objects using the internet. Nowadays, one of the most used is Low Power Wide Area Network (LPWAN) implemented over Narrow Band-Internet of Things (NB-IoT) or Long Range Wide Area Network (LoRaWAN) platforms. In this paper, a LoRaWAN architecture and infrastructure implementation is addressed to secure data and communications protecting Network Servers and communication between gateways and the demilitarized zone (DMZ), using several secure techniques and infrastructure virtualization software for containers.engLoRaLoRaWANCryptographyAESArchitectureSecurityjournal article10.1145/3696593.3696631
