Wireless sensor networks (WSNs) have attracted a lot of interests over last years in security to ensure integrity, authenticity and data confidentiality. WSN applications are numerous, which range from smart home in indoor deployment offices to smart agriculture in outdoor deployments. Due to the deployment of nodes in remote areas, the solution brought to the wireless sensor network to increase the information security consists in protecting the messages exchanged between nodes. In the paper, modifications in the key management scheme are presented. Due to resource constraints in the sensor nodes, the proposed scheme ensures a distribution of the secured keys between nodes. New session keys transmitted between sensor nodes are defined during the discovery and path key phases. The experimental results prove that the proposed scheme is adapted to the WSN applications in terms of connectivity and resiliency.
