摘要
信息技术和网络技术在电力工业中得到广泛应用的同时也带来了负面影响。文章介绍了电力信息系统安全的现状,在总结现有网络安全措施的基础上提出采用基于分片–冗余–分散(Fragmentation-Redundancy-Scattering,FRS)技术的弹性文件保护模型实现电力信息网络的容入侵,论述了相关技术及各个功能模块。最后将弹性文件模型应用于电力调度自动化系统中,并对该模型进行了分析和评价。
Along with the wide application of information and network technologies in electric power industry,the negative effects brought about by these technologies are gradually revealed.After describing present situation of power information system security,on the basis of summarizing existing network security measures a resilient file protection model based on fragmentation-redundancy-scattering(FRS) technology is proposed to realize the intrusion tolerance of power information system,and the relevant technologie...
