Abstract

This paper examines specification and implementation of secure client-server communication with the usage of cryptochip over NB-IoT network. Secure client-server connection is hardware-based, established using ATECC608a cryptochip. NB-IoT communication is achieved using Quectel BC68 module. Software, written in C, is executed on microcontroller ATSAML21J18B. Basic TLS1.3 protocol is implemented and tested.
