Abstract
The Internet of things (IoT) will accommodate several billions of devices to the Internet to enhance human society as well as to improve the quality of living. A huge number of sensors, actuators, gateways, servers, and related end-user applications will be connected to the Internet. All these entities require identities to communicate with each other. The communicating devices may have mobility and currently, the only main identity solution is IP based identity management which is not suitable for the authentication and authorization of the heterogeneous IoT devices. Sometimes devices and applications need to communicate in real-time to make decisions within very short times. Most of the recently proposed solutions for identity management are cloud-based. Those cloud-based identity management solutions are not feasible for heterogeneous IoT devices. In this paper, we have proposed an edge-fog based decentralized identity management and authentication solution for IoT devices (IoTD) and edge IoT gateways (EIoTG). We have also presented a secure communication protocol for communication between edge IoT devices and edge IoT gateways. The proposed security protocols are verified using Scyther formal verification tool, which is a popular tool for automated verification of security protocols. The proposed model is specified using the PROMELA language. SPIN model checker is used to confirm the specification of the proposed model. The results show different message flows without any error.
Highlights
The Internet of things (IoT) is a large-scale paradigm
As the IoT paradigm is built upon smart connected heterogeneous objects, the objects need to be identified in a way that improves data analysis experiences as well as reduces the risk of miss leading results based on data collected from a compromised IoT object [1]
We have addressed the issue of localization of identity management near to the gateways and described how secure communication is possible in IoT infrastructure
Summary
The Internet of things (IoT) is a large-scale paradigm. In the IoT paradigm devices communicate with each other regardless of their owners. The fundamental blocks of any IoT solution are connected devices, communication networks, services, management, security, and applications [1,5]. Traditional internet security algorithms are not appropriate for the IoT paradigm due to the heterogeneous and dynamic behavior of large numbers of IoT devices [2,6]. Innovative services based on the internet of things (IoT). The identity management of heterogeneous devices is still an open challenge [1,8,11,12] Motivated by this we have proposed a novel model for identity management of the internet of things (IoT) devices. We have described how to secure data communication between IoT devices and the corresponding gateways. Before describing our proposed model, we will discuss some relevant terms which will lead the readers to understand our model
