SI‐AKAV: Secure integrated authentication and key agreement for cellular‐connected IoT devices in vehicular social networks

Abstract

Vehicular social networking (VSN), as a novel communication paradigm, exploits opportunistic encounters among vehicles for mobile social networking, collaborative content dissemination, and to provide a variety of services for users and their vehicles. VSNs promise to solve problems such as the ever-increasing number of road accidents, or traffic congestion, by forming networks of vehicles whose users share common interests. However, in particular in urban regions, VSNs benefit from extending far beyond vehicular networks with their road side units, by integrating all kinds of sensors to provide higher accuracy and additional information in increasingly crowded areas. Integrating such sensors turns VSNs into networks of cellular-connected IoT devices with mobile cells and raises the question how to authenticate all these units in a scalable, efficient, and anonymous manner. In this article, we present SI-AKAV, an efficient group-local authentication scheme for cellular-connected IoT devices, which is specifically tailored to overcome the high computational costs of existing schemes, while improving in all of the above dimensions. For example, compared with the state-of-the-art authentication and key agreement protocol (AKA), SI-AKAV reduces communication volume by 29% and computation overhead by 41%.

A novel communication‐aware adaptive key management approach for ensuring security in IoT networks

“…The transmission time is estimated between devices where the requests are switched over. The rate of requests serviced must satisfy the criteria as in Equation (2). where r d is the density of device requests accepted for processing.…”

“…Decentralized processing, service concentric applications, ubiquitous access, interoperability, scalable and flexibility are some of the benefits of IoT. 2 In an IoT environment, the data is envisioned in digital format through internet enabling the communication of heterogeneous devices. In particular, the data sharing and access, cooperative service, network management, security features are inherited in the same platform for all the communicating devices.…”
