Key management is the core of security protocol for wireless sensor networks deployed in the hostile environment. Due to the strict resource constraints, traditional asymmetric key cryptosystems, such as public/private key based schemes, are infeasible for the wireless sensor networks. The existing random key based key pre-distribution schemes only provide some level of network resilience, as the...
Establishment of pairwise keys in wireless sensor networks is a fundamental security service, which forms the basis of other security services such as authentication and encryption. However, due to the resource constraints on sensor nodes, establishing pairwise keys in wireless sensor networks is not a trivial task. For the existing key pre-distribution schemes, as the number of compromised nodes...
