摘要：Wireless sensor networks (WSN) usually consists of a large number of tiny sensors with limited computation capability, memory space and power resource. Sensor networks are widely used for applications such as environmental monitoring, airports safety, health care, etc. The communication of a wireless sensor network can be captured quite easily, thereby it requires security. To achieve security in wireless sensor network, key pre-distribution is essential. Many key pre-distribution techniques have been developed recently to establish pair wise keys between sensor nodes in WSN. In this paper, we have proposed improved pairwise key management scheme based on deployment knowledge of the wireless sensor networks. Compared with previous proposed key pre-distribution schemes, the proposed method could significantly improve the performance and energy efficiency of the sensor nodes. It is very suitable for the sensor nodes that are limited in power, computational capacities, and memory. The proposed scheme is substantially more resilient against sensor nodes capture [7].
