摘要
新型电力系统建设涉及多业务系统、多部门、多方主体间进行海量、异构数据的交互和共享,电力数据的内外部网络环境与安全形势日趋复杂化,数据流通的脆弱性风险加剧。首先,分析新型电力系统下数据流的类型与特性,概括电力数据流通安全防护面临的新形势;其次,基于专用数据处理器(DPU)的高性能流量编排和多功能安全网关能力,构建面向电力数据跨域流通安全增强的泛安全边界,凭借数据面可编程技术沟通网络安全与数据安全双维度安全能力,提出基于DPU的数据跨域流通协同防护技术应用方案;最后,阐释DPU在不同电力通信网络层次的部署方式、价值与关键技术,分析现阶段DPU在电力领域应用存在的挑战。
The construction of the new power system involves interaction and sharing of massive and heterogeneous data among multiple business systems,departments,and agents.The internal and external network environment and security situation of power data are becoming increasingly complex,and the vulnerability risk of data circulation increases.First,this paper analyzes the types and characteristics of data flow in the new power system,and summarizes the new situation faced by the security protection of power data circulation.Then,based on the high-performance traffic orchestration and multifunctional security gateway capabilities of the data processing unit(DPU),the ubiquitous security boundary is constructed to enhance the security of power data cross-domain circulation.With the help of data-plane programmable technology,the dual-dimension security capabilities of network security and data security are communicated,and a DPU-based application scheme of collaborative protection technology for the cross-domain data circulation is proposed.Finally,this paper explains the deployment methods,values,and key technologies of DPU at different levels of power communication networks,and analyzes the challenges of DPU application in the power industry at present.
