摘要
在工业物联网的应用场景中,常规的隐私信息安全共享方法依赖于中心化的数据验证、存储和共享机制,这种结构存在单点故障风险。一旦中心服务器受到网络攻击,系统将面临大量、无序的请求挑战,共享机制会变得不稳定,进而引发共享抖动,严重威胁隐私信息的安全性。为此,提出一种基于区块链技术的工业物联网隐私信息安全共享方法。根据当前的测定需求及标准,先部署信息采集节点。利用区块链技术设置多个目标区块链,将节点采集的数据多目标地上链,增加数据上链的容错性,减少单点故障的影响。在实现多目标上链的基础上,建立起共享请求机制,有序可控地处理共享请求,以降低因无序请求导致的系统抖动。为了进一步保障隐私信息安全,利用区块链的去中心化、数据不可篡改等特性,构建一个去中心化的数据共享模型。在此模型中,设定严格的访问权限并启用共享追踪功能,能够及时发现和处理潜在的安全风险,确保数据共享的安全性和可控性。测试结果表明:应用所提方法进行物联网隐私信息共享,其抖动值均小于2.5 ms,表现优于对比方法,应用效果更佳。
In the application scenarios of the industrial Internet of Things,the conventional privacy information security shar⁃ing method relies on the centralized data verification,storage and sharing mechanism,which has a single point of failure risk.Once the central server is attacked by the network,the system will face a large number of disordered request challenges,the sharing mechanism will become unstable,and then cause the sharing jitter,seriously threatening the security of privacy information.To this end,a method of sharing industrial privacy information based on blockchain technology is proposed.Deployment information collec⁃tion nodes first according to current determination requirements and standards.The blockchain technology is used to set up mul⁃tiple target area blocks,and the data collected by nodes is multi⁃target above⁃ground chain,so as to increase the fault tolerance of the chain on the data,and reduce the impact of a single point of failure.On the basis of realizing the multi⁃objective upper chain,a sharing request mechanism is established to process the sharing requests in an orderly and controllable way,so as to reduce the sys⁃tem jitter caused by the disordered requests.In order to further guarantee the security of privacy information,a decentralized data sharing model is built by using the characteristics of decentralization and data imtamability of blockchain.In this model,strict ac⁃cess rights and shared tracking function are enabled,which can detect and handle potential security risks in time and ensure the se⁃curity and controllability of data sharing.The test results show that the proposed method is applied to share the privacy information of the Internet of Things,and the jitter value is less than 2.5 ms,which is better than the comparison method,and the application ef⁃fect is better.
