Abstract: Internet of things (IoT) is the promising technology in which devices equipped with processors, actuators and sensors communicate with each other to serve a meaningful objective. Security is the essential requirements and authentication plays a vital role in IoT system. This paper is a comprehensive attempt to provide state of art survey of available centralised and distributed authentication scheme until 2020. The comparison has been carried out in terms of various factors network model, type of architecture, application domain and IoT layers. Based on the finding, it can be observed that 'IoT architecture' and 'how the authentication is performed' criterion can play an important role for deciding the authentication scheme. This paper provides summary of wide range of authentication schemes with the help of showing their strengths and limitations. The paper introduced a conceptualisation process of authentication for IoT, which constitutes a footstep for researchers working under different application domain.
