Formulating A Global Identifier Based on Actor Relationship for the Internet of Things

Abstract

The Internet of Things (IoT) promising a new generation of services been offered to a human being through a world of interconnected objects (called "things") that may use different communication technologies. Objects, in IoT, are seamlessly connected on its owner/user behalf. To offer services, the service providers need to truly identify the effective actor/user rather than the communicated devices. Currently, users have relationships with multiple objects that can also be used to determine their user. These relationships between actors are changeable or may even vanish; however, they are important to distinguish the actual requester of the service. Hence, it is important to consider them when identifying the effective actor of the communicated object. This paper models these relationships, representing them in a general form, and proposes a new semantic identifier format that allows service providers to identify the service requester identity across domains based on those relationships.

Identification of IoT Devices for Forensic Investigation

“…One of such methods, regarding device identification, is demonstrated by [18]. Making use of the formal method and set theory, allowed [18,19] to simply utilise previous terms as well as develop novel terms and formulae for a Universal Identification Number (UID) for IoT devices which he referred to as the Global Actor Relationship Identifier (GARI) method. For this process, the methods utilised, allowed to approach the issues of IoT device management and identification in the most sensible way.…”

“…These pieces of evidence are very crucial during an investigation, be it a physical or digital one. Previous research has suggested methods to manage IoT devices globally, however, these did not consider variables such as the implementation of identification numbers in an IoT Forensics environment, which is of high necessity in today's day and age of SC and the IoT usage increase [19]. Our proposed idea suggests, an approach similar to DNA analysis regarding IoT forensics, however, instead of using traditional DNA, as we are talking about technology, we propose a method to allocate a unique identification number to IoT devices worldwide.…”

Survey of Authentication and Authorization for the Internet of Things

“…The problem of assigning identity to devices is described in [47]. An IoT device inherits the identity of its user through various methods based on a relationship between the user and the device.…”

“…Most of the surveyed proposals contain an identity management, authentication, or authorization service. An application in the IoT environment may offload the authentication process to such a security service [16,17,21,23,27,32,35,47]. A few proposals also allow the distribution of access rights or other properties used for authorization from the service to its clients [15,21,46].…”
