| Abstract | Due to recent technical advances in both wireless communication and smart device capabilities, Internet of Things (IoT) emerges as the novel enabling paradigm for various smart city applications, including smart transportation, smart energy, smart water, and smart home. Because of the critical or even life-dependent nature of many such applications, security and trustworthiness have both become major concerns for the integration and utilization of both sensing and actuating capabilities in IoT. In addition, mobile crowdsensing has recently emerged as an additional means that complements the existing infrastructure-based sensing paradigm, which is also vulnerable to various cyberattacks. In this chapter, we will investigate the security and trust issues in IoT-based smart city applications and explore how to enhance their security and trustworthiness by using the emerging blockchain technology. More specifically, the threat model, attack surface, and the corresponding countermeasures for IoT-based smart cities will be first investigated. Then, we will explore how the blockchain technology could help one to enhance the security and trustworthiness in IoT. Finally, some existing challenges and future research directions will both be discussed. |
