Securing a wireless communication has generally a vital importance, particularly when this communication is in a hostile environment like in wireless sensor networks (WSNs). The problem is how to create cryptographic keys between sensor nodes to ensure secure communications. Limited resources of sensor nodes make a public key cryptosystem such as RSA not(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)
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)
