The IP-based Internet of Things (IoT) refers to the pervasive interaction of smart devices and people enabling new applications by means of new IP protocols such as 6LoWPAN and CoAP. Security is a must, and for that we need a secure architecture in which all device interactions are protected, from joining an IoT network to the secure management of keying materials. However, this is challenging because existing IP security protocols do not offer all required functionalities and typical Internet solutions do not lead to the best performance.
