Access Control Schemes for Machine to Machine Communication in IoT: Comparative Analysis and Discussion

摘要

The ubiquitous access to devices and resources brings revolution to our lifestyle. But at the same time, we are facing various challenges and issue due to weak security and access control policies. In this paper, we have studied various access control policies which are implemented in a wide variety of applications but these mechanisms are unable to fulfill the requirement of Internet of Things (IoT) services. In gap analysis, we have identified crucial factors like privacy, scalability, usability, trust, and heterogeneity and based on these factors we have done a comparative study of various access control methods. Furthermore, we have proposed a scalable framework for trust-based access control. The proposed mathematical model addresses the various aspects for the development of a trust management framework.
