Identity Management in the Internet of Things: A Survey of the State of the Art

Abstract

The Internet of Things (IoT) facilitates connections between people and things at any time, anywhere, with anything, and with anybody through the use of any network, service, or application. The IoT is a system of actual physical objects commonly referred to as things . Things contain sensors, software, and other technologies that connect to other systems and devices over the Internet and allow data exchange. Identity management (IDM) involves managing identifiers and attributes linked to identity, and access management involves evaluating these attributes and making decisions based on policies to manage access to other objects or services. Authentication, authorization, and access control collectively represent identity access management.
