Validation of IoT secure communication gateway for constrained devices

This article deals with the challenge how to secure communication of constrained embedded devices via the Internet of Things protocols. The main focus is paid on a secure communication gateway, which is designed to enhance the security level of communication for constrained devices. The goal is to classify devices according to communication needs and associate needed measures (partitioning). The proposed gateway is focused on D2D and D2S application protocols. Validation of the proposed model was done for MQTT and CoAP protocols.
