摘要: 对偶密钥的建立是研究传感器网络安全的关键问题之一。该文采用超立方体模型的节点编码,结合网络节点的期望位置信息,提出了一种基于混合超立方体模型的多项式对偶密钥建立算法。实验结果显示该算法具有建立直接密钥概率较高、存储开销合理等良好性能。

Abstract: Pairwise key issue plays a key role in sensor networks security. An approach on pairwise key establishment based on location awareness is proposed. The algorithm encodes sensor nodes on a hybrid hypercube model with information of nodes’ expected location. Experimental results show that the algorithm has nice features such as higher probability of direct key establishment, reasonable storage cost and good scalability on network scales.

Key words: location awareness, pairwise key, sensor networks, hypercube
