摘要: 针对现有异构传感器网络(HSN)密钥预分配方案的安全问题,提出一种基于部署知识和密钥链技术的对密钥建立方案。将部署区域划分成多个单元,整个HSN网络划分成簇。在部署区域中,相邻节点使用预分配密钥信息建立共享密钥。在节点部署完成后,当两相邻节点不能建立共享密钥时,通过其他高能节点为其分配共享密钥。理论分析和模拟结果表明,该方案的存储开销和计算开销小,局部连通率高,对抗节点俘获的弹性性能和安全性能好。

Abstract: Aiming at the security deficiency of the pre-distribution scheme for Heterogeneous Sensor Network(HSN), a security pairwise key establishment scheme based on key chain and deployment knowledge is proposed for HSN. The deployment area is divided into multiple cells, the HSN is divided into multiple clusters. Two nodes whose deployment cells are adjacent can establish a common key by using pre-distribution keys. After deployment, if two neighboring nodes can not establish a common key, the common key must be distributed by other high energy node. Theory analysis and simulation results show that the scheme makes much more improvement than the classical scheme for HSN on the memory overhead, the local connectivity rate, the resilience against node capture.

Key words: Heterogeneous Sensor Network(HSN), key chain, rabin scheme, local connectivity rate, shared key
