In recent years, use of sensors to measure the biometrics and movements of human body have resulted in the design of wireless body area networks (WBAN). Although WBANs consist of resource constrained sensing devices just like other wireless sensor networks (WSN), they differ from WSNs in topology, scale and security requirements. Due to these differences,(More)
Wireless body area networks (WBAN) consist of resource constrained sensing devices just like other wireless sensor networks (WSN). However, they differ from WSN in topology, scale and security requirements. Due to these differences, key management schemes designed for WSN are inefficient and unnecessarily complex when applied to WBAN. Considering the key(More)
In many of the sensor network applications like natural habitat monitoring and international border monitoring, sensor networks are deployed in areas, where there is a high possibility of node capture and network level attacks. Specifically in such applications, the sensor nodes are severely limited in resources. We propose MUQAMI, a locally distributed key(More)
Bardram introduced a new concept of activity-based computing as a way of thinking about supporting human activities in ubiquitous environments. In such environments where users are using a multitude of heterogeneous computing devices, the need for supporting users at the activity level becomes essential. However, without considering basic security issues,(More)
