TL;DR: The WoT based Asset Description (WoT-AD), a descriptive language for the Asset aiming to mitigate limitations in Massive IoT scenario, is introduced and a lightweight framework that fully integrates with WoT- AD to enable WoT formassive IoT scenario is provided.
Abstract: Recently, the Massive Internet of Things (IoT) and Web of Things (WoT) are remarkable research fields aiming to facilitate the connectivity, accessibility, and control of the Things by Web standards and technologies for large-scale deployment. In such context, the end-user is capable of simply creating, mashing-up, and presenting the multiple Things to gain high-level information. However, current research approaches much more pay attention to describe a single Thing. The modeling and building the application for the compound objects consisting of groups of Things namely "Asset" are still limited due to the lack of description and seamless integration mechanism. Moreover, the traditional IoT Device Description Language directly installed on device is highly restricted in Massive IoT scenario because of stringent requirements for power consumption and operation cost. In this paper, we introduce the WoT based Asset Description (WoT-AD), a descriptive language for the Asset aiming to mitigate such limitations. WoT-AD explicitly describes a group of Things as homogeneous object to enable mash-up, self-discovery, and simply access their resources, entities, and services. We also provide a lightweight framework that fully integrates with WoT-AD to enable WoT for Massive IoT scenario. Such integration not only effectively models the Asset but also simplifies the development of mash-up application to different-skilled users. Finally, we evaluate the performance of our proposal to demonstrate its effectiveness and scalability in real use-case.

TL;DR: In this article, the authors focus on the mechanisms to engineer authentication, authorization, and trust among the IoT Platform elements, where JSON Web Token (JWT) based authentication and authorization are described.
Abstract: Ensuring adequate security features for the Inter-net of Things (IoT) Platforms is often challenging. This paper focuses mechanisms to engineer authentication, authorization, and trust among the IoT Platform elements. JSON Web Token (JWT) based authentication and authorization are described. Trust is established by mutual certificate based authentication. We have shown how these security features have been incorporated in the EURECOM IoT Platform.
