摘要: 针对现有分簇式无线传感器网络密钥管理方案中存在的健壮性差、簇头节点抗俘获性差和可扩展性差等问题,结合组合设计和基于身份密码体制的思想,提出一种新的密钥管理方案。采用组合设计的方法构造每个簇的密钥池,使簇内节点均共享一个密钥。簇内节点使用椭圆曲线密码体制建立簇内对密钥,簇头节点使用基于身份密码体制建立簇头之间对密钥。该方案支持节点动态变化。性能分析表明,与现有的分簇式密钥管理方案相比,该方案具有良好的健壮性、簇头节点抗俘获性、可扩展性和较低的系统开销。

Abstract: The existing clustered key management scheme for Wireless Sensor Networks (WSN) has poor robustness, resilience of cluster head nodes and extensibility. This scheme took the composite design to construct the key subset of cluster in order to make all the nodes in the same cluster share a common key. The nodes in the same cluster took the Elliptic Curve Cryptography (ECC) to establish the pairwise key between the nodes, and the cluster head nodes of more energy took the identity-based encryption to establish the pairwise key between the cluster head nodes. In this scheme, the nodes could join and leave networks dynamically. The performance analysis shows that this scheme has good robustness, resilience of cluster head nodes and extensibility with lower communication overhead and storage cost.
