Privacy Preservation and Security Dilemma : Relationship proposition for IoT authentication

Internet of Things (IoT) authentication demands a complex approach to ensure all facets of security are taken care of. Security in IoT is not complete without looking at privacy protection especially if sensitive data is involved. Privacy of user credentials is critically important as that holds pieces of data that can compromise the whole security system. The need to emphasize on privacy preserving for authentication is on the basis that, we need to complete the security puzzle unequivocally. One of the security worries in IoT is user data privacy as a result of the unsupervised nature of IoT device’s interaction. Focusing on smart home environments and personal area networks to a large extent, this paper gives an overview on some of the existing solutions that employs privacy preserving attributes towards providing IoT authentication security solutions in the quest to try and provide the relationship between privacy and security.
