摘要
随着我国新基建战略的提出,大数据、人工智能和5G网络必将得到进一步的飞速发展,物联网作为其关键组成部分也越来越受到人们的广泛关注和深入研究.无线传感网络是物联网发展的重要组成部分,广泛应用于军事、交通、工业和日常生活.因此,无线传感网络的安全性显得尤为重要.由于受能量、存储和空间等资源的限制,现有的重量级安全认证方法并不适用于无线传感网络.基于区块链的设计思想,提出一个轻量级的无线传感网络安全认证模型解决无线传感器网络终端的数据安全问题.该模型将传感网络分为全局网络和本地网络两层,本地网络采用非对称加密进行集中式安全认证;全局网络采用有向非循环图(DAG)和Tangle(缠结)技术来构建账簿,并采用关键节点和随机游走方法进行一致性验证.
With the proposal of China's new infrastructure strategy,big data,artificial intelligence and 5G network will get further rapid development,and the Internet of Things(IoT),as a key component of it,has attracted more and more extensive attention and in-depth research.Wireless sensor network(WSN)is an important part of the development of IoT,which is widely used in military,transportation,industry and daily life.Therefore,WSN security is particularly important.Due to the limitation of energy,storage and space,the existing heavyweight security authentication methods are not suitable for WSN.Based on the design idea of blockchain,this paper proposes a lightweight WSN security authentication model to solve the data security problem of WSN terminal.In this model,the sensor network is divided into global network and local network.The local network uses asymmetric encryption for centralized security authentication;the global network uses directed acyclic graph(DAG)and tangle technology to build account books,and uses key nodes and random walk method to verify the consistency.
