This paper assesses the power consumption of a proposed algorithm for path key establishment for wireless sensor networks. This algorithm elects trusted common nodes called "Proxies" residing in an existing secure path linking two sensor nodes which can be used to transmit the new generated key. The generated key is divided into a number of parts depending on the number of elected proxies...
Wireless sensor networks are composed of large number of sensor nodes with limited communication and processing power. Key pre-distribution schemes using a shared large key pool have been proposed in order to overcome power and memory constraints. Establishing a secure link depends on the probability of sharing a key (secret) between two sensor nodes. In this paper, we propose a new approach for path...
Key management plays an essential role in achieving security in wireless sensor networks (WSNs). A range of new key distribution schemes have been suggested in an attempt to improve existing ones which are inappropriate for WSNs. However these schemes are still vulnerable when a certain number of sensor nodes are captured. The key distribution proposed in this paper makes use of coordinator sensor...
