Abstract
This research work greatly concerning the trending Protocol known as Message Queue Telemetry Transport (MQTT) which is used by Internet of Things (IoT) to pass messages by both ends. The communication between the huge amounts of devices is enabled by IPv6 and light weight communication protocols such as MQTT. The goal was to develop a protocol which is bandwidth-efficient and uses little battery power. Most of the present-day surveys focusing on IoT MQTT protocol protection. Even though security is very much concerned, it is also important to concentrate on MQTT messages with its types, structure and so on.
Highlights
The prevalence of embedded devices with their very own memory and computational power, as well as the ability to connect with each other, has given rise to new attack vectors that have proven difficult to protect against
According to [1], interconnected devices such as sensors, appliances, and cameras represent some of the components of this network, which was named the Internet of Things (IoT) by Kevin Ashton at a conference in 1999
Eclipse’s open-source application, called Mosquitto, is able to provide most of standardized features of the Message Queue Telemetry Transport (MQTT) protocol, such as SSL/TLS and client certificate support
Summary
The prevalence of embedded devices with their very own memory and computational power, as well as the ability to connect with each other, has given rise to new attack vectors that have proven difficult to protect against. The IoT became possible by the sudden increase in smart devices that manufacturers developed and released on the market. MQTT is a messaging protocol that uses the publish-subscribe communication model, where the clients themselves do not require updates, in turn causing a reduction of used resources, which makes this model optimal for use in a low-bandwidth environment. Every MQTT message contains a topic, organized in a tree-like structure, to which the clients can subscribe or publish. The broker receives published messages from clients that contain a certain value or command and relays the information to every client that has subscribed to that specific topic. Eclipse’s open-source application, called Mosquitto, is able to provide most of standardized features of the MQTT protocol, such as SSL/TLS and client certificate support. Authentication information is sent in plaintext; it requires security mechanisms to protect the transferred information.[3]
