Summary

During the past years, with the adoption of the IPv6 protocol which has provided us with a vast amount of addresses available for use at anything we might want, together with the need to have every single of our devices and appliances connected to the Internet in order to be controlled by our mobile devices, the technological term “Internet of Things”, also abbreviated as IoT, has resurfaced. That is an indeed very trending topic today and it is estimated that by 2020, almost 50 billion “things” will be connected to the Internet. However, having all these devices connected to the Internet, which, as we already know, is not exactly what one would deem a “safe place”, harbors a great deal of dangers and vulnerabilities that could render any device accessible to a malicious user. In order to protect our “things” and our transferred data, we need to implement security mechanisms. The problem is that due to the constrained hardware and resources of these devices, not every existing security mechanism can be successfully implemented on them. In this thesis, the MQTT protocol was selected, among other IoT communication protocols, as a foundation, on top of which we will develop different lightweight security implementations for Wireless Sensors Nodes running the Contiki OS for Internet of Things. However, given the importance of security in IoT and because of the many options in relation to where and how to implement security mechanisms in MQTT, a comparison and an assessment of the performance of these options will be made in order to designate the best one
