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。
Research on the key management scheme of the existing wireless sensor network is not difficult to find that the random key management scheme is more suitable for the current wireless sensor network. The program is for a random program to improve. Most current key management schemes are a hybrid mechanism that combines the advantages of multiple key management schemes. The proposed improvement scheme is a key management scheme that combines the advantages of combining a hybrid key management scheme that involves deployment and zoning. Analysis and simulation show that this scheme can improve security and reduce node storage and communication overhead.
