Abstract

In recent years, security has become one of the major concerns in IoT. As a result, a variety of emerging technologies and new standards have been developed over the past few years to effectively increase the security capabilities of the IoT systems. At the same time, performance still remains as another fundamental aspect of IoT. Current IoT systems feature constrained capabilities, which in turn might constitute a significant barrier for the development of new IoT technologies. Consequently, performance has to be taken into consideration when applying new security features to IoT. This paper presents an in-depth performance analysis on the security of two of the most established communication protocols in IoT: CoAP and MQTT. In particular, it focuses on transport layer security (DTLS, TLS) and recent standardization work on end-to-end application layer security (OSCORE, EDHOC). In order to further asses the feasibility of the protocols, the message reliability capabilities of each protocol have also been considered in the analysis. The scope of the evaluation has been defined in terms of latency and throughput consumption. Based on this evaluation, IoT adopters can adequately select the best IoT security communication protocol for their own IoT applications.
