As Wireless Sensor Networks (WSNs) are usually deployed in remote or even hostile environment, the adoption of security mechanism is fundamental. To achieve secure communication between sensor nodes in WSNs, it is important to establish efficient key pre-distribution schemes. Unfortunately, key management scheme is a challenging issue for WSNs because of the resource limitations in the sensor nodes. In this paper, the authors propose an efficient key management scheme for WSNs, which assigns the key spaces to sensor nodes via combinatorial design.
