The use of wireless sensor networks (WSNs) in any real-world application requires a certain level of security. To provide security of operations such as message exchange, key management schemes have to be well adapted to the particularities of WSNs. This paper proposes a novel key management scheme called SKM for sequence-based key management in WSNs. In(More)
Ensuring key management in Wireless Sensor Networks has a vital importance, especially when sensor nodes have to communicate in hostile environments. In this paper, we propose a new simple and resource-aware key management scheme. The scheme is based on the idea that the initial pre-distributed key is not pre-loaded in all nodes to improve its resilience to(More)
