Due to the sensitive nature of the data gathered by many wireless sensor networks (WSNs) it is becoming critical that this data be protected. However, due to the constrained nature of the resources available on sensor nodes, traditional wireless networking security solutions are not viable because of their processing and memory requirements, power consumption, speed and communications overhead. In...
Key management is a decisive part for security in wireless sensor networks. Pre-distribution of secret keys for all pairs of nodes is not viable due to the large amount of memory used when the number of sensor node is huge. Recently, a random key pre-distribution scheme is proposed as an efficient solution for sharing keys among sensor nodes to reduce the length of shared key and avoid unnecessary...
