Position: Middle-Senior C/C++ Embedded developer for Microcontrollers
Company: Intecracy Group
Experience required: 2y

The project is about the Implementation of the authentication protocol for different IoT devices in the network by following blockchain philosophy which allows to define whether newly appeared in the network device or sensor can be authenticated and authorized. This protocol is written on C/C++ language, thereby alowing the protocol to be platform independent and applicable for authenticating wide range IoT devices (as Raspberry Pi 3B+, different routers) by different communication channels (cellular 4G, WiFi 2.4 & 5 GHz, Bluetooth LE 4-5, Waitless-N, P, ZigBee, Thread (6LoWPAN), Sigfox, LoRa, NB-IoT, Ethernet, RS-232, RS-485).


Responsibilities: Development platform - independent C library for ARM based microcontrollers (STM32F407 and similar) which implements highly secured authentication algorithm.

Project consists of two parts:

-development of library which implements main authentication workflow on Linux environment, documented and covered by unit tests
-porting workflow to ARM based microcontroller (STM32F407 ...).
