The Internet of Things poses some of the biggest security challenges in the present day. Companies, users and infrastructures are constantly under attack by malicious actors. Increasingly, attacks are being launched by hacking into one vulnerable device and hence disabling entire networks resulting in great loss. A strong identity management framework can help better protect these devices by issuing a unique identity and managing the same through its lifecycle. Identity of Things (IDoT) is a term that has been used to describe the importance of device identities in IoT networks. Since the traditional identity and access management (IAM) solutions are inadequate in managing identities for IoT, the Identity of Things (IDoT) is emerging as the solution for issuance of Identities to every type of device within the IoT IAM infrastructure. This paper presents the survey of recent research works proposed in the area of device identities and various commercial solutions offered by organizations specializing in IoT device security.

Swarms of embedded devices provide new challenges for privacy and security. We propose Permissioned Blockchains as an effective way to secure and manage these systems of systems. A long view of blockchain technology yields several requirements absent in extant blockchain implementations. Our approach to Permissioned Blockchains meets the fundamental requirements for longevity, agility, and incremental adoption. Distributed Identity Management is an inherent feature of our Permissioned Blockchain and provides for resilient user and device identity and attribute management.

In the future Internet of Things, it is envisioned that things are collaborating to serve people. Unfortunately, this vision could not be realised without relations between things and people. To solve the problem this paper proposes a user centric identity management system that incorporates user identity, device identity and the relations between them. The proposed IDM system is user centric and allows device authentication and authorization based on the user identity. A typical compelling use case of the proposed solution is also given.
