Abstract

Internet of Things (IoT) is one of the promising technologies that has attracted a lot of attention in both industrial and academic fields these years. It aims to integrate seamlessly both physical and digital worlds in one single ecosystem that makes up a new intelligent era of Internet. This technology offers a huge business value for organizations and provides opportunities for many existing applications such as energy, healthcare and other sectors. However, as new emergent technology, IoT suffers from several security issues which are most challenging than those from other fields regarding its complex environment and resources-constrained IoT devices. A lot of researches have been initiated in order to provide efficient security solutions in IoT, particularly to address resources constraints and scalability issues. Furthermore, some technologies related to networking and cryptocurrency fields such as Software Defined Networking (SDN) and Blockchain are revolutionizing the world of the Internet of Things thanks to their effi- ciency and scalability. In this paper, we provide a comprehensive top down survey of the most recent proposed security and privacy solutions in IoT. We discuss particularly the benefits that new approaches such as blockchain and Software Defined Networking can bring to the security and the privacy in IoT in terms of flexibility and scalability. Finally, we give a general classification of existing solutions and comparison based on important parameters.

10. Conclusion

The Internet of things is a new paradigm that comes to revolutionize the world through the connection of various physical objects to the Internet in order to form one unified and intelligent ecosystem. A new intelligent world is emerging nowadays where humans, smart-phones, computers and new intelligent objects are connected to the Internet. In this paper, we surveyed security solutions proposed for Internet of Things’ applications. We first categorized the different IoT applications by identifying their security requirements and their inherent challenges. Then we discussed the IoT solutions dealing with con- fidentiality, privacy and availability which are based on traditional cryptographic solutions. We also reviewed some emerging technologies such as Blockchain and Software Defined Networking which are considered as efficient mechanisms to deal with scalability issues in IoT. Finally, we discussed some security solutions that take care of the context in which IoT applications involve and also the different impacts of security issues on the safety of systems and some countermeasures. Comprehensive comparison of the different approaches was provided based on some criteria, we investigated also some analysis of which techniques are suitable for each kind of IoT application. Despite the efforts that have been spent to deal with the various challenges to which Internet of things face, it’s still a lot of open issues to be addressed such as scalability and dynamism issues, especially because Internet of Things is becoming an Internet of Everything where humans, data, processes and objects are evolving together in highly dynamic and complex system.
