A Survey on IoT Privacy Issues and Mitigation Techniques

Abstract

Internet of Things (IoT) has emerged as a global network, which intelligently connects different devices or systems which are having self-configuring capabilities. The key idea is to bind or to connect miscellaneous devices or objects via wireless or wired connections along with unique addressing system and make omnipresent environment where an individual can communicate at any time with digital and physical word. It has conspicuous vulnerabilities because of increasing number of omnipresent devices. That is why for conveying data at application layer, resource constrained machines are supposed to exploit Constrained Application Protocol (CoAP) which was standardized by Internet Engineering Task Force (IETF). CoAP has previously accepted as the paradigm protocol for IoT systems. But, privacy of CoAP is yet an open Challenge. As it influences an individual's daily life it is indispensable to allow security services like authentication, confidentiality, authorization etc. This survey presents an overview of CoAP as well as current situation of security and privacy in Internet of Things that is required to be solved and discuss the further work.
