The invention provides an attack identification method based on a K nearest neighbor algorithm, which comprises the following steps: if a normal database and an abnormal database after being attackedby a network are established, taking all classifications as reference sample groups to obtain a reference database; extracting real-time data from a message, and classifying the real-time data and thereference database through a K nearest neighbor algorithm to obtain the category of the data; sending an attack alarm and generating a log record for storage when the real-time data includes the dataclassified into a network attack category, and intercepting the data classified into the network attack category; meanwhile, forwarding the data classified into a normal category in the real-time data; and forwarding the real-time data when the real-time data does not include the data classified into the network attack category. The invention further provides a charging device. Compared with theprior art, the information safety and the operation reliability of the charging device are ensured, and the safety of a power grid is ensured.

    本发明提供了一种基于K最近邻算法攻击识别方法,包括如建立正常数据库以及被网络攻击后的异常数据库,将所有分类分别作为参考样本组得到参考数据库;提取报文中的实时的数据后将实时的数据与参考数据库通过K最近邻算法对实时的数据进行分类,得出数据的所述分类;当实时的数据中存在数据归入的分类为网络攻击类别时,发出攻击报警和生成日志记录进行保存,同时对归入网络攻击类的数据进行拦截;同时对实时数据中归入正常类的数据进行转发;当实时数据中不存在数据归入的分类为网络攻击类别时,则将实时数据进行转发。本发明还提供了一种充电装置。与现有技术相比,保证充电装置的信息安全性以及运行可靠性,保障电网的安全。
