Identity Management in Internet of Things: A Software-Defined Networking Approach

Abstract

Internet of things (IoT) network needs to accommodate billions of connected smart objects (things). Connected IoT objects should be able to communicate with each other. Objects should be able to travel between different networks regardless of their locations, network providers, and manufacturers. To allow transparent movement of IoT objects it is very important to have a trust relationship between these objects. To establish trusted relationship, unique identity is one of the key properties for any IoT object. It will not be possible for the devices to freely move within the networks, if we do not have a common identity solution. The use of software defined networking (SDN) approach in IoT is increasing these days, due to its flexibility and easy adaptability with any network. In this paper we have presented an SDN based identity management system which will possibly solve the unique identity problem and increase trust in heterogeneous IoT network.

Survey on Identity and Access Management for Internet of Things

“…However, once it is employed in Cloud technology, we still consider it mobile. In fact, mobility is so vital that some works, like z [95,99], have this mobility as the main factor when developing their proposal and utilizes it for its own good. It is important to point out that the work [23] utilizes the self-sovereign model, but once it only creates a local DLT unable to interact with the wold, we consider it immobile.…”

“…To offer a proper answer to flexibility problems, the works [111,112], for example, alleges that cloud has limited flexibility to support IAMs and point out fog computing as the solution of the flexibility and the latency problem originated by the cloud. In [99], the author utilizes fog devices of different platforms to perform the authentication and authorization, which can significantly reduce the delay of those functions and the flexibility of the IAM as a whole. Lastly, when we observe DLT-based IAMs [107,23,108], it still in the early stages, with several workings being published recently.…”

“…A malicious user can execute a manipulation to trick patients, setting their permissions into the patient's devices, resulting in a device that gives away sensitive information about the patient without any form of consent. • Identity Management for the Internet of Things: A Software-Defined Networking Approach: Sadique et al [99] propose an IAM architecture based on concepts of Softwaredefined networks. Authors argue that IoT is composed of different objects, and these objects should be able to travel among different networks, regardless of their locations, network providers, and manufacturers.…”

“…However, as pointed out by [110], the centrality of those kinds of solutions may not be the best one when dealing if IAMs. Some works, like [99], avoids this centricity by employing fog computing nodes in their IAM system, to deal with the IAMs in a distributed manner, which can be more appropriate when dealing with IoT. However, some works like [107,23,108] take it to another level and employes the DLT as the main technology behind their IAM.…”

IMSC-EIoTD: Identity Management and Secure Communication for Edge IoT Devices

“…After the authentication process, the authorization takes place. 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.…”
