- � Springer International Publishing Switzerland 2015.The Internet of Things (IoT) is one of the most novel networking paradigms and there are yet too many technologies defining themselves as IoT complicating the scenario for developing a fully IoT environment. The situation becomes even harder when security and privacy are considered. In this paper, we present a survey on the security aspects of an IoT conformed by wireless sensors communicating through the IEEE 802.15.4 standard. This survey follows a revision of the state of art in a layer-by-layer systematic analysis.
