Unique characteristics of wireless sensor networks have made node compromise a great security challenge. An adversary can use compromised nodes to inject false data to the network, thus deceiving the sink to make false decisions. Moreover, the false data will deplete precious energy resources of en-route nodes which forward the false data to the sink. To fight against such false data injection attacks,...
Self-healing key distribution enables users in a large and dynamic group to establish session keys for secure group communication over an unreliable network. The main property of self-healing key distribution is that the users are capable of recovering lost session keys on their own, without requesting additional transmissions from the group manager. In this paper, we propose a self-healing key distribution...
Dynamics of sensor networks make security one of the top issues we should pay attention to. Sensor networks can be deployed in hostile environments where their nodes are easy to be captured or re-programmed for deleterious use by an adversary. Therefore, it is necessary to protect communications between sensor nodes through cryptographic methods. To address this, symmetric key management in wireless...
