Critical Security Mechanism Designed for Data Transmission in Wireless Sensor Networks using Hierarchical Cloud Server

Abstract

The rapid advancement of pervasive computing, IoT and wearable systems, given rise to low-power internet-based systems in elimination of distance complications by application of Wireless Sensor Networks, which consists of sensor, server and Cloud servers to sense various environmental readings and monitor the condition based on the data. Due to the association of vital data, and transferring it over an insecure and public communication channel, there is a critical prerequisite for sensor authentication, data integrity and data privacy. In this context many researchers had proposed various schemes for user authentication and secure data transmission over Cloud server. In this paper we proposed a three-factor user authentication and key agreement protocol for cloud server and claimed that the proposed protocol is efficient, secure and lightweight. The experimental analysis shows that the proposed scheme is resistance to well-known cryptographic attacks. Though the proposed scheme resists major cryptographic attacks, after in-depth analysis, we demonstrate that the scheme overcome many security pitfalls such as failure to resist replay attack, known session-specific temporary information attack, and failure to resist stolen-verifier attack.
