Experiments with wireless sensor networks have shown that unidirectional communication links are quite common. What is even more, they have also shown that the range of a unidirect...
We consider group key agreement (GKA) protocols, used by a group of peers to establish a shared secret key for multicast communications. There has been much previous work to impro...
Introducing mobile data sinks into wireless sensor networks (WSNs) improves the energy efficiency and the network lifetime, and is demanded for many application scenarios, such a...
Finding flaws in security protocol implementations is hard. Finding flaws in the implementations of sensor network security protocols is even harder because they are designed to p...
The intent of this paper is to propose an energy-efficient routing protocol with data transmission security for wireless sensor networks. We create an energy and distance aware sin...
