A taxonomy of identities management systems in IOT

Internet of Things viewed as Future Internet aims to provide the capacities for each physical entity to be connected to the Internet and to establish its requirements services or to be attached to a distributed system computing. Therefore, each object must have its identity (ies) that permits accomplishing the authentication and authorization phases before beginning every secure transaction. Hence, the number of identities increase at least according to the number of connected object. Today, several challenges such as security, privacy and identities management must be taken into account. In this paper, we propose a taxonomy of identities management systems (IDMS) in Internet of Things (IOT) relying on the viewpoint of paradigms and models. We present the core components of an Identity management system. Discuss the different types of IDMS paradigms such as User Centric, Application and Network Centric. Also, we present a comparative analysis of Identity management models: - user model, service provider (SP) model, Combining user and SP model in the form of Taxonomy and we discussed the Related Works of IDMS of IOT.
