Dongfeng Fang, Yi Qian, Rose Qingyang Hu · 2023
Recent advancements in communication technologies and integrated circuits have fueled the widespread adoption and integration of Internet-of-Things (IoT) applications, creating a pervasive environment rich in both challenges and opportunities. This chapter aims to explore flexible and efficient security schemes for IoT applications that consider the comprehensive trust model and account for the heterogeneity of IoT devices. It presents a general IoT system architecture along with the corresponding trust models, threat models, and design objectives. The chapter presents an investigation into an flexible and efficient scheme for authentication and secure data transmission, aiming to achieve mutual authentication and the agreement of an initial session key while maintaining anonymity. It evaluates the performance of the proposed scheme in three key areas: security services provided, computational overhead, and communication overhead. In 5G wireless systems, network slicing can be utilized to manage the resources based on specific applications dynamically.
