摘要:A large amount of data information will be generated during the construction and operation of the power system, and once these data are leaked, it will undoubtedly threaten the information security of power users, which will bring avoidable economic losses to power companies and users. Therefore, many electric power companies are paying more and more attention to data security, and data encryption technology solves this problem well. And this article has launched a detailed analysis on the application of data encryption technology in the construction of electric power information. At the same time, it has carried out an in-depth discussion with the practical application of the two-layer encryption method in the informationization of electric power enterprises. I hope the research results of this article It can provide a certain reference for the information security management of the power system.
