Active power distribution network big data transmission method based on behavior marking and lightweight encryption

Abstract

The invention belongs to the field of power grid data security. The method is mainly used for solving safety and efficiency problems in data transmission. The invention particularly relates to an active power distribution network big data transmission method based on behavior marking and lightweight encryption. The method comprises the following steps: acquiring active power distribution network big data, and dividing the active power distribution network big data into real-time data, quasi-real-time data and non-real-time data by using a convolutional neural network to extract data set features and the probability that a Softmax function outputs a category to which the data set features belong; marking and encrypting the real-time data, the quasi-real-time data and the non-real-time data;and performing data compression under multi-objective constraints on the data of each sampling point based on a distributed Agent parallel technology, and finally performing secure transmission. According to the method provided by the invention, anti-theft and anti-tampering effects in data transmission are ensured according to a data marking and lightweight stream encryption method, and rapid identification and matching of a receiver are realized, so that safe and efficient transmission of power distribution network data is ensured.

Description

technical field [0001] The invention is an active distribution network big data transmission method based on behavior marking and light encryption, which is mainly used to solve the security and efficiency problems in data transmission, and belongs to the field of power grid data security. Background technique [0002] With the continuous development of active distribution network, the use of traditional communication methods such as GPRS / CDMA, ZigBee, Wi-Fi and dedicated optical fiber for power grid data transmission can no longer guarantee the security of data transmission. And the existing wireless transmission is essentially encrypted to ensure the security of the data during transmission, because in the active distribution network environment, a large amount of collected data needs to be transmitted to the controller and the master station system for processing At the same time, it is necessary to return the processed data to the controller for scheduling and control, s...
