Security is one of the inherent challenges in the area of Wireless Sensor Network (WSN). At present, majority of the security protocols involve massive iterations and complex steps of encryptions thereby giving rise to degradation of quality of service. Many WSN applications are based on secure group communication. In this paper, we have proposed a scheme for secure group key management with si...

Protocol and technology convergence, the core of near future communication, will soon be forming the interoperating heterogeneous networks. Attaining a strict secure authentication without risking the QoS performance and call success rates is a major concern when it comes to wireless heterogeneous networks. In order to achieve this, a generic, fast and secure, Authentication and Key Agreement p...
