摘要 针对现有密钥管理方案抗俘获性差和占据存储空间大等缺点,提出了一种分层的密钥管理方案。簇头节点采用了Blom矩阵,有效提高了簇头节点抗击俘获的能力;簇内节点利用中国剩余定理,在将复杂计算转交给基站的同时,降低了组密钥的存储空间。通过对比分析,该方案较好地满足了WSNs密钥管理的相关指标,提高了安全性能。 Due to the bad resilience and large storage overhead of current schemes, this paper proposed a layered key management scheme for wireless sensor networks. Implementing the Blom-matrix in the cluster heads communication, it could effectively enhance the ability of the resilience. By means of the Chinese remainder theorem, it shifted the complexity to the base station lowering the storage consumption. Under comparative analysis, it meets the scenario of the WSNs key management and improves its security performance.
