The issue of digital identity is at the heart of many contemporary strategic innovations, covering crime, internal and external security, business models etc. The area of MANets (Mobile Ad-hoc Networks) is still in its infancy in the research community, but it plays a vital role surrounded by the growing trend of mobile technology for business, private and governmental uses. The emergent notion of...
In many applications of Wireless Sensor Networks a Sink is interested in aggregated data instead of exact values from all sensors. To send aggregated data, it is also helpful to reduce the amount of data to be transmitted and thereby conserve energy. Indeed current in-network aggregation schemes are helpful to conserve energy but they are designed without considering possible security issues related...
Key establishment and its management in wireless sensor networks is a challenging problem due to the limited resources and disordered structure of such networks. In this paper we propose a dynamic group-based key management technique. In our solution, a large-scale network is divided into small logical groups. Each group is assigned a unique master key that will be used to generate other distinct...
