| 摘 要： | 无线传感器网络(Wireless Sensor Networks WSNs)是由资源有限的传感器节点构成的无线网络。在传感器节点间建立对偶密钥是实现网络安全通信的基础。在本文中,我们提出了一种新的对偶密钥建立方案。本方案以六边形结构进行网络域分簇,利用节点的部署信息和重叠密钥共享(overlap key sharingOKS)思想给每个传感器节点预分配密钥信息。通过分析,本方案具有较高的抗节点俘获能力,能够有效减少存储开销,并提供灵活的安全等级。

| Abstract: | Wireless Sensor Networks(WSNs) are wireless networks that include sensor nodes with limited resources. For secure sensor communication, pairwise key establishment between sensor nodes is essential. In this paper, we propose a new pairwise key establishment mechanism. we cluster the network field in hexagonal shape and preassign key information for each sensor using deployment knowledge, and using the overlap key sharing (OKS) concept in spirit. Our proposal has a better resilience against node capture, efficiently decreases the memory requirement and supplies flexible security level. |
