n-Tier Modelling of Robust Key management for Secure Data Aggregation in Wireless Sensor Network

Abstract

Security problems in Wireless Sensor Network (WSN) have been researched from more than a decade. There are various security approaches being evolving towards resisting various forms of attack using different methodologies. After reviewing the existing security approaches, it can be concluded that such security approaches are highly attack-specific and doesnt address various associated issues in WSN. It is essential for security approach to be computationally lightweight. Therefore, this paper presents a novel analytical modelling that is based on n-tier approach with a target to generate an optimized secret key that could ensure higher degree of security during the process of data aggregation in WSN. The study outcome shows that proposed system is computationally lightweight with good performance on reduced delay and reduced energy consumption. It also exhibits enhanced response time and good data delivery performance to balance the need of security and data forwarding performance in WSN.

A novel key exchange algorithm for security in internet of things

“…This resulted in producing syntactically correct messages that will help to deceive the attacker trying to decrypt a cipher text with incorrect keys [23]. N-tier modelling of robust key management and a cost-effective security paradigm with 2-tier model to safeguard cloud data with effective authentication are discussed in [24,25]. The above-mentioned research efforts majorly focused on survey of internet of things and its applications for identifying the research problems and its solutions.…”
