— As the use of sensor networks increases, security in this domain becomes a very real concern. One fundamental aspect of providing confidentiality and authentication is key dis...
Distributed wireless sensor networks have problems on detecting and preventing malicious nodes, which always bring destructive threats and compromise multiple sensor nodes. Theref...
Abstract. We consider the problem of multihop broadcast over adaptively duty-cycled wireless sensor networks (WSNs) where neighborhood nodes are not simultaneously awake. We presen...
This paper presents a distributed user authentication scheme in wireless sensor networks. Our scheme is based on the self-certified keys cryptosystem (SCK), and we have modified i...
