【摘要】:提出一種傳感器網(wǎng)絡(luò)多密鑰空間分層密鑰預(yù)分配方案。該方案把部署區(qū)域劃分為正六邊形網(wǎng)格,將節(jié)點(diǎn)分成不同的簇,密鑰空間劃分為與簇相對(duì)應(yīng)的子集;簇頭節(jié)點(diǎn)之間采用多密鑰空間隨機(jī)預(yù)分配方案進(jìn)行共享密鑰發(fā)現(xiàn),簇頭節(jié)點(diǎn)與普通節(jié)點(diǎn)間則采用單項(xiàng)散列計(jì)算的方式計(jì)算共享密鑰。性能分析和仿真結(jié)果表明,該方案在連通率及抗捕獲攻擊方面有較好的性能改善,通信和存儲(chǔ)開銷預(yù)算較合理。
[Abstract]:A multi-key space hierarchical key pre-distribution scheme for sensor networks is proposed. In this scheme, the deployment area is divided into hexagonal grid, nodes are divided into different clusters, and the key space is divided into corresponding subsets. The shared key is calculated by single hash between cluster head node and common node. The performance analysis and simulation results show that the proposed scheme has better performance improvement in connectivity and anti-capture attack, and the budget of communication and storage overhead is reasonable.
