摘要：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 feasible. So, most solutions rely on a symmetric cryptosystem. In this paper, we propose a new key mana-gement scheme based on symmetric cryptography which is well adapted to the specific properties of WSNs. The evalu-ation of our solution shows that it minimizes memory occupation, ensures scalability, and resists against the hardest attack: com-promised nodes.
