Abstract: Because of the limitation of resources in Wireless Sensor Network(WSN).This paper presents a new key pre-distribution scheme based on plane grid.It not only reduces cost of storage and power,but also ensures that all neighbors’ nodes can establish pairwise keys directly.But the safety performance is poor.Then the scheme is extended to tridimensional grid.A novel key pre-distribution is proposed,which is called tridimensional grid key pre-distribution scheme.The results of analysis indicate that the scalability and resilience of the scheme is much better.

Key words: Wireless Sensor Network(WSN), key pre-distribution, plane grid, tridimensional grid

摘要: 针对无线传感器网络资源有限的特点,给出了一种基于平面格的密钥预分配方案,该方案存储开销与能量消耗较小,能确保所有邻近节点直接建立对偶密钥,但安全性能较差。然后将方案扩展到三维格上,提出了基于三维格的密钥预分配方案,分析结果表明方案具有较好的可扩展性与抵抗攻击的能力。
