Abstract [en]

The Internet of Things (IoT) is an emerging paradigm that will change theway we interact with objects and computers in the future. It envisions a globalnetwork of devices interacting with each other, over the Internet, to perform auseful action. As such, quite a number of useful and benecial applications ofthis technology have been proposed.Although a convenient technology, the use of IoT technology will add additionalrisks to our lives that the traditional Internet did not have. This is primarilybecause IoT technology allows the virtual world to directly aect the physicalworld.Therefore, ensuring security is of paramount importance for IoT technology. Assuch, this thesis has two aims. First, we will identify the security issues for IoTtechnology as well as highlight what approaches academia has developed to resolvethem. This will allow us to see the state of this technology along with whatstill needs to be done in the future. Secondly, we will analyze some security protocolsproposed by academia and evaluate whether they ensure condentialityand authenticity.A literature survey is used to achieve the rst goal and the results show thatalthough a lot of research has been performed regarding security for IoT environments.We still have quite a way to go before a full holistic system isdeveloped which ensures all the security requirements for IoT.The results for the security protocol analysis shows that less than half of theprotocols proposed ensured authenticity and condentiality; despite the factthat their respective papers claim that they did. Therefore, we emphasize thefact that good peer reviews need to be enforced and that protocols need to bevalidated to ensure what is proposed performs as described.
