摘要
对现有无线传感器网络的密钥管理方案研究,不难发现随机密钥管理方案比较适合现阶段无线传感器网络。该方案就是针对一种随机方案进行的改进。目前大多数的密钥管理方案都是一种混合机制,即结合多种密钥管理方案的优点。提出的改进方案是一种涉及部署,区域划分等的混合密钥管理方案,将其优点相结合的密钥管理方案。分析和仿真表明,该方案提高安全性的同时降低了节点存储和通信开销。
Study on the existing key management scheme for WSN （wireless sensor network） indicates that the random key management scheme is fairly suitable for the present wireless sensor network, and this scheme is a modified model of the random key management. Nowadays most schemes are hybrid systems integrated with the merits of many key management schemes. This proposed scheme is also a hibrid key management integrated with some merits of other key management and involves deployment and domain division. Analysis and simulation show that the proposed scheme could improve WSN security while reduce the memory and communication cost.
