Abstract

<p>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.</p> <p>We propose and compare two security architectures providing secure network access, key management and secure communication. The first solution relies on a new variant of the Host Identity Protocol (HIP) based on pre-shared keys (PSK), while the second solution is based on the standard Datagram Transport Layer Security (DTLS). Our evaluation shows that although the HIP solution performs better, the currently limited usage of HIP poses severe limitations. The DTLS architecture allows for easier interaction and interoperability with the Internet, but optimizations are needed due to its performance issues.</p>
