— Broadcast authentication is a critical security service in wireless sensor networks (WSNs), as it allows the mobile users of WSNs to broadcast messages to multiple sensor nodes...
Intrusion or misbehaviour detection systems are an important and widely accepted security tool in computer and wireless sensor networks. Their aim is to detect misbehaving or faul...
In this paper, we analyze attacks on existing time synchronization protocols for wireless sensor networks. We propose a secure time synchronization toolbox to counter these attack...
Secure communication in wireless ad hoc sensor networks is a major research concern in the networking community. Especially the few available resources in terms of processing powe...
We will demonstrate a wireless sensor network system for the surveillance of critical areas and properties – e.g. borders. The system consists of up to 10 sensor nodes that moni...
