Securing IoT Using Decentralized Trust Privacy and Identity Management
- 2024

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Internet of Things (IoT) is a multidisciplinary area where technology meets people, enriching their quality of life with an improved working environment and efficient productivity. As the number of IoT devices increases, many new technology areas are being integrated with the IoT. IoT devices mainly connect and collaborate with central cloud servers for data management. The IoT paradigm is built upon the Internet and accesses different layers of Internet architectures. IoT devices are at the access layer of the Internet, and cloud servers are located at the top layer. The innovative use cases of IoT applications drive the requirement for quick decision-making that occurs as close to the source of information as possible. IoT devices need to be authenticated near the source for rapid request processing. Trustworthy interaction and secure communication between different entities of an IoT paradigm are crucial. A centralized cloud-based implementation of IoT solutions can be problematic for ensuring trustworthy and authenticated interactions in which quicker decision-making is involved. Additionally, privacy leakage possibilities increase with cloud-based solutions, as they involve multiparty interactions, introducing more complexity into ensuring data privacy. Due to IoT application and service heterogeneity, traditional security models are unsuitable for the IoT. There is no generic model for IoT data security and user data privacy that can facilitate trustworthy collaboration and identity management near the source.The thesis focuses on creating a generic state-of-the-art artefact for IoT security, utilizing decentralized trust, user data privacy, and localized identity management for heterogeneous IoT devices and services. The main contributions of this thesis include a novel decentralized model for secure and reliable interaction between components of the IoT paradigm, complemented by a decentralized trust management model, an edge gateway-based privacy enhancement scheme, and a decentralized identity management model with new authentication and authorization mechanisms for IoT devices where access to new resources is granted locally, and activities are recorded with context information. The proposed models are generic and can be easily adapted to real-life IoT use cases with minor amendments.

- Extended reality (XR) enables both new opportunities but also introduces new barriers for inclusion in society. Furthermore, XR is less researched than web, desktop and mobile applications. This position paper presents the concept of an XR platform for inclusion, with the purpose to make people on the autism spectrum and with other disabilities, more independent of help from others in everyday life situations. Based on previous research, our position is that, through current and future XR technologies combined with civic and artificial intelligence, it is possible to create individually personalised support for this purpose, grounded in practice to ensure validation.

Konferensbidrag (refereegranskat)abstract
- A common challenge for people on the autism spectrum with intellectual disability, is indoor navigation and related daily activities, as found in previous research. In this paper we report on co-design of assistive augmented reality applications, where the goal is to help people on the autism spectrum to gain more independence in their daily lives. This study is based on initially two full-day workshops with staff only, followed by ten individual workshops with the end-users and their staff at day centers, using a mix of methods and prototypes. The results show a clear potential of augmented reality as assistive technology for indoor navigation, depending on individual capability and/or complexity of environments, as well as for other activities. We also found that new barriers may arise, which are discussed for future research.
