Wireless Sensor Networks (WSN) security is an important issue which has been investigated by researchers for few years. The most fundamental security problem in WSN is key management that covers the establishment, distribution, renewing and revocation of cryptographic keys. Several key management protocols were proposed in the literature. Unfortunately, most of them are not resilient to nodes capture. This means that an attacker compromising a node can reuse the node’s key materials to populate any part of the network with cloned nodes and new injected nodes. In this article, we present a simple polynomial-based key management protocol using a group-based deployment model without any necessary predictable deployment location of nodes. That solution achieves high resilience to nodes compromising compared with other protocols.
