An Enhanced Optimal Fair Exchange Protocol for Enhancing Security and Authenticity in a Three-tier WBAN Architecture
Siva Bharathi K R and Venkateswari R
Wireless Body Area Networks, measured to be a subset of Wireless Sensor Network summonses the attention of various researchers to deal with countless medical applications in recent days. It is also observed that local servers and database servers are used in hospital to store such sensitive data collected from various sensors. There are chances of misinterpreting these sensitive data while it gets gathered, stored, preprocessed and finally accessed. Security is an important challenge being faced by wireless body area networks, instigating severe performance degradation in fetching and accessing patient’s sensitive data thereby compromising the authenticity of information. Thus, security and privacy become two key anxieties in the field of Wireless Body Area Network which are to be addressed with utmost care. This paper focuses on a replacement key management E-OFE (Enhanced Optimal Fair Exchange) Protocol for group- based communications in non-hierarchical body sensor networks (BSNs), applied on a recently proposed TPA-based multicast protocol. Confidentiality, integrity, and authentication are conventional, using exclusively symmetric-key-based procedures. Our proposed results show recently proposed TPA-based multicast protocol. Confidentiality, integrity, and authentication are conventional, using exclusively symmetric-key-based procedures. Our proposed results show that our proposed dealings have the potential to signiﬁcantly reduce the fraction of packets being dropped without affecting Routing for low-power and lossy networks (RPL’s) performance when there is no attack. We also evaluate the performance of our enhanced E-OFE using Cooja, the Contiki network simulator.
