基于区块链的工业互联网安全平台

Industrial Internet Security Platform Based on Blockchain

在传统的工业互联网平台中,终端设备产生数据的安全和隐私问题是阻碍工业互联网发展的主要瓶颈.伴随着终端数据量几何式的增长,保护数据的安全性和完整性已经成为工业互联网的核心研究领域.本文首先设计了一种基于区块链的设备和数据管理的体系架构,提供了一个可靠的防篡改的数据库.然后,利用数字证书对平台采用权限访问控制机制,提高平台的准入的安全等级.其次,通过链码间接地对终端设备及其配置文件进行管理,避免了终端设备随意地接入对数据造成污染的问题.最后,通过终端设备自身的公私钥来对终端设备产生的数据进行打包加密处理,利用区块链的共识机制,存储在区块链上.通过实验表明,所提出的方案具有良好的稳定性、安全性和可操作性.

In the traditional industrial Internet platform, the security and privacy issues of data generated by terminal equipment are the main bottlenecks hindering the development of the industrial Internet. With the geometric growth of terminal data, protecting the security and integrity of data has become the core research area of the industrial Internet.This study first designs blockchain-based equipment and data management architecture, providing a reliable, tamper-proof database. Then, the digital certificate is employed to provide the authority access control mechanism for the platform to improve the security level of platform access. Secondly, the terminal equipment and its configuration files are managed indirectly through the chain code, which avoids the data pollution caused by the random access of the terminal equipment.Finally, the data generated by the terminal equipment is packaged and encrypted through the public and private keys of the equipment itself and then stored on the blockchain with the consensus mechanism of the blockchain. Experiments show that the proposed scheme has good stability, safety, and operability.
