一种无线传感器网络的密钥管理机制

Key management scheme for wireless sensor networks

介绍了一种用于无线传感器网络(WSNs)的密钥预分配机制:多密钥空间哈希随机密钥预分配(HARPMS)机制。该机制针对group-based节点投放模型,将密钥空间划分成多个子空间,在密钥分配和建立时使用Hash链技术,以提高网络的抗节点俘获能力。分析表明:相比传统的用于group-based投放模型的随机密钥预分配机制,HARPMS获得了同等的连通性,但却有更好的抗节点俘获能力。

A key pre-distribution scheme for wireless sensor network （WSNs）：Hashed random key predistribution using multiple key spaces （ HARPMS ） is presented. In HARPMS, aimed at the group-based deployment model,the key space is partitioned into some subspaces ,and in key distribution and setup phases the Hash chain technology is used to improve the WSNs resilience against node capture. The analyses show that compared with the traditional random key pre-distribution scheme for group-based deployment model, the HARPMS has the same connectivity but better performance in resilience against node capture.
