Abstract: Internet of things (IoT) refers to intelligent technologies and services that connect all objects based on the internet to communicate information between people and things, things and systems. However, these IoT-based devices are exposed to many security threats because they communicate information to each other over wired and wireless networks. Recently, international standards organisations such as the IETF have sought to establish the IoT by developing technologies that allow devices with various physical constraints to connect to the internet. However, it will not be easy to meet the new requirements associated with the IoT, where countless devices are connected to the internet and require large amounts of data processing. Therefore, in this paper, we analyse ZigBee, CoAP, MQTT, and XMPP, which are technologies related to IoT, and propose the security requirements that the components that make up the IoT should have.

Keywords: security; internet; internet of things; IoT; ZigBee; constrained application protocol; CoAP; message queuing telemetry transport; MQTT; extensible messaging and presence protocol; XMPP.
