A performance analysis of the security communication in CoAP and MQTT

Security and performance are both key aspects for the Internet of Things (IoT). Therefore, performance has to be considered 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.

#CoAP #MQTT

In particular, the analysis focuses on Transport Layer Security (DTLS, TLS) and recent standardization work on end-to-end application layer security (OSCORE, EDHOC). 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 our evaluation, IoT adopters can adequately select the best IoT security communication protocol for their IoT applications.
