Título: | Security and Privacy for Mobile IoT Applications Using Blockchain | Autor: | Carvalho, Kevin Granjal, Jorge |
Palavras-chave: | IoT; privacy; security; location; blockchain; MQTT | Data: | 3-Set-2021 | Editora: | MDPI | Projeto: | CISUC - UID/CEC/00326/2020 | Título da revista, periódico, livro ou evento: | Sensors | Volume: | 21 | Número: | 17 | Resumo: | Internet of Things (IoT) applications are becoming more integrated into our society and daily lives, although many of them can expose the user to threats against their privacy. Therefore, we find that it is crucial to address the privacy requirements of most of such applications and develop solutions that implement, as far as possible, privacy by design in order to mitigate relevant threats. While in the literature we may find innovative proposals to enhance the privacy of IoT applications, many of those only focus on the edge layer. On the other hand, privacy by design approaches are required throughout the whole system (e.g., at the cloud layer), in order to guarantee robust solutions to privacy in IoT. With this in mind, we propose an architecture that leverages the properties of blockchain, integrated with other technologies, to address security and privacy in the context of IoT applications. The main focus of our proposal is to enhance the privacy of the users and their data, using the anonymisation properties of blockchain to implement user-controlled privacy. We consider an IoT application with mobility for smart vehicles as our usage case, which allows us to implement and experimentally evaluate the proposed architecture and mechanisms as a proof of concept. In this application, data related to the user's identity and location needs to be shared with security and privacy. Our proposal was implemented and experimentally validated in light of fundamental privacy and security requirements, as well as its performance. We found it to be a viable approach to security and privacy in IoT environments. | URI: | https://hdl.handle.net/10316/105463 | ISSN: | 1424-8220 | DOI: | 10.3390/s21175931 | Direitos: | openAccess |
