SMCRP: A Secure Multicast Certificateless Routing Protocol for Network Security in WBAN

Abstract

In Wireless Body Area Networks (WBAN), key factors are important issue to be considered for confidential data transmission that includes data security and privacy in emergency medical response systems. Comparing to Sensor Ad hoc Networks (MANET), security is a major concern in WBAN. Hence in this research, a Secure Multicast Certificateless Routing Protocol (SMCRP) for withstanding attacks in body area networks. It consists of three phases. First, the secure cluster topology is constructed in the body sensor networks based on path reliability and trust recommendation of sensor nodes. Second, the signcryption and unsigncryption phases are performed together to verify the authenticity of sensor nodes. Third, the secure multicast group management is performed to avoid replay attacks and to keep network connectivity. Last the packet format of proposed protocol ensures high confidentiality between the sensor nodes located in body area networks. Based on the extensive theoretical and practical simulation results, the proposed protocol achieves better performance interms of computational cost, time, delay, packet drop, delivery ratio, end to end delay.
