Abstract
For security in Internet of Things, access control is achieved by using another method as compare to the old way. So, the main purpose of this paper is to survey the access control and authentication in IoT. Here we describe various type of access control models, framework and protocols, which are used in IoT. The need for security and privacy for IoT devices is illuminated here. Moreover, assessment of various schemes related to access control in IoT over the latest years is discussed. Lastly, we provide guesses for upcoming research in the field of access control in IoT. On the basis of shortcomings observed in the existing model, the proposed model is designed to protect IoT networks with context-aware access control scheme. The proposed model covers the access control policy for IoT networks with context awareness. This model simplifies the node recognition procedure by using the ontology, which will be used to describe the node identity, node's network performance and data transmission procedures.
