摘　　要：随着电网规模的发展,电网数据海量增加,但是当前电网数据安全传输系统由于应用的数据加密技术较为落后,对海量数据的处理效果较差,导致其抗攻击能力较低,故本文设计了基于混沌加密的电网数据安全传输系统。在硬件设计中,优化嵌入式控制器以及信息存储电路,为软件优化提供基础。在软件设计中,借助四维Chen离散处理技术以及混沌动力学理论设计电网数据加密模块,并采用加权残差检测数据交汇过程,构建电网数据网络攻击检测模块,完成电网数据安全传输系统设计。实验结果表明:本文所设计系统的抗攻击敏感度与加密耗时均优于当前系统,可将其应用到实际工作中。With the development of power grid scale,the power grid data increases massively.At present,due to the backward data encryption technology and poor processing effect of massive data,the power grid data security transmission system has low anti attack sensitivity.Therefore,a power grid data security transmission system based on chaotic encryption is designed.In the system hardware design,the embedded controller and information storage circuit are optimized to provide the basis for software optimization.In the software design,with the help of four-dimensional Chen discrete processing technology and chaotic dynamics theory,the power grid data encryption module is designed,and the weighted residual is used to detect the data intersection process,build the power grid data network attack detection module,and complete the design of power grid data security transmission system.The experiment results show that the anti attack sensitivity and encryption time of the system designed in this paper are better than the current system,and can be applied to practical work.
