Abstract
Background/Objectives: Internet of Things (IoT) has made significant changes in the real world and penetrates all aspects of human life. The user acceptance of IoT is enormously high and its widespread usage is because of the availability of smart phones and tablets. Wide adoption of IoT in the applications of each field always collecting sensitive information and provide a larger surface for intruders. So privacy preserved authentication and access controls are big challenges in its research area. Methods/Statistical Analysis: In this paper we introduced a novel algorithm based on Zero Knowledge Protocol and Accumulated Hashing to provide secure authentication to sensor enabled mobile devices in IoT. Also for ensuring confidentiality in communication proposed a new method for key exchange using current time. Findings: The proposed method fulfills the requirements of resource and battery constrained mobile devices in IoT when compared with traditional authentication and access control mechanisms for other applications.
