WSNs中一种基于簇结构的密钥预分配方案

Key pre-distribution scheme based on cluster in WSNs

为了解决无线传感网络中簇结构的基础安全问题,提出一种二层二项式密钥预分配方案,它能够很好地完成两簇头间密钥对的生成,满足对节点极小的能量损耗、极少的通信负载和存储空间要求。它有效地解决了节点获取攻击问题,提高了网络恢复度,同时成功地解决了多项式密钥预分配方案中的"K-security"问题。

To solve the problem of basic security for clustering in WSNs, this paper proposed a new bivariate polynomial key pre-distribution scheme based on two-tier hierarchical network architecture in WSNs. The scheme established pairwise key between any two cluster heads and suitable for the limited battery power, memory storage, and data processing capacity condition. The scheme not only successfully improved the network resilience against node capture attacks, but also solved the ＂K- security＂ problem of polynomial-key pre-distribution schemes.
